Introduction to LiberaToe Pedal
Despite living in the era of technological evolution that even enable probes to land on Mars, one simply cannot give up analogue sound. In keeping the analogue based classic sound, we have incorporated the key advantages of digital technologies, such as flexibility and ease of control. Previously, achieving both was difficult because both the sound processing and the signal control were intended to be processed only in either fully analogue- or fully digital form.

LiberaToe combines these two qualities - previously were deemed mutually exclusive - boutique-level, high-quality audio and ease of operation thanks to the separation of the sound effects into analogue circuit and software-based signal control. As a result, LiberaToe maintains a decent sonic while achieving intuitive operability.

All of the LiberaToe pedals feature dual channels, which are rarely found in conventional pedals.

Some of them adopt heterogeneous dual channels which provide two different effects, the others feature homogeneous dual channels which have identical effect.

Dual Channels
In addition to the A / B selection function, some pedals in the series offer a variety of uses, such as A > B(serial) or A // B(parallel).

Guard Rail
Rail is fitted to protect the knob and toggle switch settings from foot movement.
True Bypass
It is equipped with a gold-clad relay to faithfully output the original sound as it is in bypass.
Double Power
Both 9V and 18V are available for each purpose. 18V, which is made by boosting the 9V input, is rated up to 500mA current, unlike ordinary low-cost step-up devices with a limit of 10mA.
Analogue Sound
According to each purpose, different technologies are adopted so that sound processing is handled by analogue circuitry and only the signal routing function is controlled by the embedded software in MCU.

How to switch Dual Channels of the LiberaToe Pedal
So how do you choose between two channels as well as bypass with a single foot switch? A short press on the foot switch turns the green channel on. Press it again to return to bypass. Long press instead of short press activates red channel. Short press in this red channel also returns to bypass and long press returns to green channel again. In this way, a single foot switch that supports two channels is the world's first feature, with embedded software for control that is completely separate from analogue sound processing.

Foot Switch Operation
Short-press for on/off and long-press for channel switching is factory default for foot switch action. It will be available later on paid repair to change the switch behavior into short-press for channel switching and long-press for on/off.
Press and release immediately to switch between on and bypass. Press more than 0.4 sec ti switch between green and red channels.

Features in Detail
Many guitar amplifiers have almost two or more channels built in, and their structure is high quality based on analogue circuitry. In the world of analogue effects, almost all products have supported only a single channel, for example of overdrive, only gain, tone, level. Though some products support two channels, separate channel select switch is added to incur inevitable increase of weight and volume.

This is because technically all processing and control has been implemented in analogue only or digitally only. As digital effectors process both sound and control in software, many functions can be implemented at a low cost. However, the unique ‘picking dynamics’ provided by analogue processing reproduces the feelings and technique of the performer as well, especially in the live scene. It is well known that digital devices are difficult to provide picking dynamics, are thus usually used in the recording.

The development of this new product was done by the global team with experts from a wide range of fields that required integrated technology, supported by hardware design while processing sound with analogue engineering and controlling signal routing with embedded software.

Internally, the embedded software, which is a digital technology, works, but the user experience is thoroughly pursued with analogues, so the intuitive usability of the knobs that are operated by hand and the familiar footing of the analogue devices that keep the tapping foot switch intact are also advantages in reducing fatigue as many things are going digitized.

Developers have dual channels in every effect they design to provide multichannel functionality like a tube amplifier, while adopting an analogue sound processing method that allows the px-layer to enjoy picking sensitivity. In case of overdrive, gain 1 + tone 1 + level 1 operates in the green channel and gain 2 + tone 2 + level 2 operates in the red channel. Or in overdrive with TMB tone stack, for the most important middle control, a channel with a middle knob that can be adjusted and another channel that middle is fully fixed on are implemented.

'Dual Channel' is not only implemented on homogeneous effects but also on heterogeneous effects. By the development team carefully considering the number of cases in which each effector is used, for example such as using a separation or a combination of 60's vintage fuzz and WahWah, you can use the two-stage or three-stage toggle to set the desired combination into two channels.

Therefore, in addition to selecting between A / B channels(by selection), some pedals provide various uses such as A to B (in series) or A & B (mix) in the LiberaToe dual channel pedal series.

In order to make such a variety of sounds, circuits requiring high voltages and high currents have been developed, instead of using a low-current 9V power. Unlike low-cost devices that typically only provide 5~10mA by boosting 9V to 18V, all LiberaToe pedals are designed to utilize up to 500mA enough current for both 9V and 18V power. (To do this, use a power adapter with sufficient current capacity)

The LiberaToe Pedal implements 'True Bypass' equipped with a high quality gold-clad relay to bypass the original sound faithfully.

In addition, due to the nature of the pedals equipped with the control knobs, toggle switch and foot switch together, a rail is installed to separate the control compartment from the foot switch to prevent the control knobs or toggle switch from being accidentally changed when the foot switch is pressed.

Combination Examples of Dual Channel Pedals
In general, when using one or more of overdrive, boost, and distortion, and using space-time effects such as delay and chorus, at least four pedals are configured, which normally requires extra equipment. Using only two pedals from the LiberaToe pedal family, MonkHawk, Luther or Blue Crow and Robofish, you can choose any combination between dry, boosted overdrive and/or distortion, in combination with chorus, tremolo and delay. The reason for this is that Robofish has a simple programmable loop that supports 3 loops and 2 channels. This configuration will cover almost all genres.
Instead of Luther and MonkHawk, you can replace the higheror lower-gain LiberaToe pedals or replace the multi-effector Robofish with individual space-time LiberaToe pedals to cover different genres (jazz, thrash metal, etc.). As another example of a combination, Gnavatar will be able to combine Baron Ashura with the ability to parallelize existing pedals while providing advanced noise reduction and compressor combination. You can also add ProudAnus with built-in fuzz and envelope filters to create funky tones.
The combination of Bass-specific Holy Belly equalizer/booster with Baron Ashura or ProudAnus on the front is great. And if you're using four of them with the addition of Gnavatar, bass-only overdrive Bentham, or BearAss with integrated fuzz and compressor, this analogue effects set will be the strongest combination for the bass.
On existing pedal boards, you can add Brever to the end of the effect chain if you want to have reverb effects and the entire sound mastering as like in the studio. The reverb-only dual channel selection gives you the option of light reverb and deeper spatial reverberation in live, plus a variety of options for mastering effects alone or in combination with reverb, so that you can enjoy the benefits as like being supported by a studio engineer.



T2. Alter Ego Delay

Alter Ego Delay is a perfect reincarnation of a Tape Echo's warm vintage delay. Two channels, Short Delay and Long Delay, allow you to select different delay times, repeats, and mix amounts in real time. Depending on the need, you can choose either the mutual tails between the two channels, or only the long delay channel.

In addition, the dual delay function allows you to mix repeating sounds into long and short channels to create unique effects, and to adjust the delay in real time using the Tap Tempo function which is run by dedicated tap tempo switch box to be released soon. These features are a paradigm shift from conventional classic analogue delay products. The Tap Tempo is also adjustable using foot switches in the LiberaToe platform product range.

If you want a warm vintage delay tone of tape echo based on a transparent bypass with less coloration, but want to play with two channels with different delay times, repeat counts, and mix amounts, and want to sometimes use a long delay time over the tape echo? For those who need it, Alter Ego Delay is recommended also for those who want to create a variety of tones on a small pedal board using a full pedal with dual channel and tails as well as tap tempo.

* When external momentary switch cable is plugged in the round jack on the top, Delay 2 time can be adjusted by its tap action.
* When Platform tap toggle is up, Delay 2 time can be also dialled by Tap Tempo foot switch in the LiberaToe platforms.
This feature is only supported by the module type units found in the LiberaToe platforms, such as LiberaToe-6, LiberaToe-4.
* Alter Ego Delay matches well with a buffer in its immediate front or rear position, or an input buffer-equipped effector.

① Time1,2: echo faster clockwise
② Repeat1,2: more iteration clockwise
③ Mix1,2: louder repeat signals clockwise
Warning : Do not plug DC power cable into round jack on the top




T4. Brever Reverb

Brever Reverb reproduces the classic spring reverb band that was built into the 60s vintage tube amps, while offering dual channels as in the other products of the LiberaToe series. Each channel is equipped with two knobs, allowing you to adjust the amount of the reverb wet sound and overall volume. Using this function, you can match the volume level with other effects in the front.

At the same time, Reverb Channel 1 adds a Decay pot for adjusting the reverb time, a tone pot for adjusting the reverberation tone without changing original signal, and a last-level tone make-up to the amplifier, taking advantage of the reverb at the end of the signal chain.

This makes it possible to enjoy the semi mastering work on stage as if it was the final stage of studio recording, on the red channel. Depending on the selection of toggle switch in this heterogeneous effector, you can finally master the entire tone, either alone or behind the reverb. For those who want to create more precise analog reverb tones with the Decay and Tone knobs, which are not commonly found in the pedal type, for those who want to use two channels with different reverb settings, and for those who want a mastering function to tune the frequencies as a whole, and for those who want to create various sounds on a small pedal board using a pedal with two different functions, Brever Reverb is recommended as a heterogeneous dual channel effector.

① Reverb1,2: controls define how to mix dry and wet signals, more wet reverb clockwise, more dry signal counter-clockwise
② Decay1: control defines how long the wet signals stay on the green channel
③ Level1,2: louder clockwise
④ Tone1: more edge of wet signals clockwise on the green channel
⑤ High: amplify higher frequencies to let them sound lucid
⑥ Low: emphasize low frequencies to complement bass contents




G6. Blue Crow Overdrive & Distortion

Blue Crow Overdrive Distortion Combination is a twin channel effects that integrates classic overdrive and vintage distortion. It includes an overdrive that acts like a preamp inside a large tube amp head, and a distortion that acts like a power amp that produces a tenacious break-up through massive output. Blue Crow not only acts as an overdrive for the amp’s dirty channel, but also utilises its own crunch gain to faithfully reproduce the overdrive's inherent peaking dynamics and boost the built-in distortion behind it.

The mid-high gain vintage distortion perfectly expresses the rock spirit of the 70's and 80's, providing a wide range of driving sensations, from crisp to creamy tones thanks to the high headroom from 18V. On low and high presence setting for large amplifiers, or relatively high presence setting for small amplifiers, the tone can be balanced to produce a wider distortion in the British amplifier itself

When the toggle is turned up, the LEVEL and BOOSTED functions of the distortion can be set up independently, for example, each for the backing and lead volumes.

In other words, on the red channel, overdrive and distortion are stacked and used similarly to the overdrive input for an amplifier gain. This method is used to minimise the gain of the overdrive together with the appropriate DIST level, or to slightly reduce the DIST of the distortion and increase the gain of the overdrive.

Thus Blue Crow is a versatile analogue effects with 3 usages, boosted distortion, as well as overdrive and distortion, a revelatory improvement from the single effect, providing you with thick and powerful gain.

① Level of distortion (green channel)
② Level of distortion boosted by overdrive (red channel)
③ Presence of distortion
④ Tone of distortion
⑤ Dist: gain of distortion
⑥ Gain of overdrive
⑦ Edge: tone of overdrive
⑧ Volume of overdrive (red channel)




D4. BearAss Compressor & Fuzz

Bear Ass Compressor & Fuzz is a dual channel effects that integrates compressor and fuzz to an exceptional quality. The compressor unit is ambidextrous to provide a role of sustain & boost as well, whilst maintaining the attack and creating a natural compression. Therefore, while the compressor works on the green channel, the sustain & boost function operates on the red channel. The fuzz section covers a wide range of tones from sticky to a substantial amount of furry and outrageous tones, allowing you to make a wide range of adjustments just by using the fingers controlling the instrument’s volume knob.

When the toggle switch is down, the compressor (front) and fuzz (rear) work together to create a relatively soft tone on the green channel. This means that in the fuzz you can set two different sounds for each of the green and red channels to choose between the two fuzz tones according to your purpose. Unlike typical fuzz, this fuzz can be placed anywhere in the effect chain. This effect can also be used for the bass.

① Boost: control overall volume of sustaining effect (red channel)
② Level: control overall volume of compression effect (green channel)
③ Sust: adjust compression ratio while keeping attack alive (red channel)
④ Comp: adjust compreession ratio (green channel)
⑤ Volume: adjust overall volume of fuzz effect
⑥ Tone: adjust tone of fuzz effect
⑦ Fuzz: control the amount of adbrasiveness and hairiness
⑧ Voice: control the amount of brightness of compressor and sustainer




T5. Robofish Multi-effects

Robofish multi-effector is the world's smallest analogue multi-effector, featuring delay, tremolo, and chorus in a tiny programmable loop. Three frequently used spatial-temporal analogue effects can be set on / bypass and assigned to green or red channels, respectively, as required.

Therefore, two pre-sets among seven cases - with the exception of the bypass - can be used simultaneously, and a combination of 49 branches is possible. In these pre-sets, the delay tails feature is activated, tremolo achieves a fairly high speed, and the chorus has a wide range of application, from vibrato to deep throb chorus, depending on the Rate and Depth knob settings.

In addition, very extreme tones can be produced if set after 4 o'clock. Pre-sets are intuitively designed for simple operation, by turning up corresponding bars on the two DIP switch units used for green and red respectively. For those who want to use three types of effects such as delay, chorus, and tremolo in an analog pedal, and those who want to easily set various combinations of two channels, and those who want the tails of delay in this pedal, Robofish multi-effector is recommended.

① Rate-C: going faster chorus clockwise
② Depth-C: getting deeper chorus clockwise
③ Speed-T: going faster tremolo clockwise
④ Depth-T: getting deeper tremolo clockwise
⑤ Volume-T: louder tremolo clockwise
⑥ Time-D: faster delay clockwise
⑦ Repeat-D: more iteration of delay clockwise
⑧ Mix-D: louder repeat signals clockwise




G7. Darwin Overdrive

Darwin Overdrive is a top touch-sensitive overdrive. Like other products of the LiberaToe series, dual channels are provided, each of which is fitted with gain and level. The middle knob on the green channel allows you to vary the tone of middle range. The Treble knob delivers strong impression in the high-pitch range, unlike the fragile high notes of conventional pedal-type overdrive or distortion. Additionally, the DeFAT knob can be used to create muscular gain so as to eliminate the fuzzy sound-like side effect in the bottom frequencies. As a result, together with Presence knob, you have two additional fine-tune methods, both high- and low end.

① Middle 1: adjust decibel of mid range on green channel (mid level fixed internally on red channel)
② DeFAT: adjust bass contents, more bass in counter-clockwise, low cut in clockwise
③ Level 1,2: control overall volume of each channel
④ Gain 1,2: control gain of each channel
⑤ Treble: adjust decibel of high frequencies on both channels
⑥ Bass: adjust decibel of low frequencies on both channels
⑦ Presence: adjust brightness depending on amp's character


Thanks to the ample headroom created by the internal 18V power supply, the solidity of the gain is nearly identical to that produced by a legendary tube amplifier, loved by stripped-guitar-ist, even when it is used to a typical clean channel amplifier. Together with its dual channel capability, you can now enjoy a performance which is as good as a specialised high-gain amplifier.
