LiberaToe Pedal & Module
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 a single channel as like, for example of overdrive, only gain, tone,and level. Though some products support two channels, a channel selection switch is added to incur the increase of weight and volume.
This is because technically effect and control have been implemented in analogue only or digitally only. As digital effects process both sound and control in software, many functions can be implemented at a low cost. However, the unique picking dynamics provided by analogue circuitry reproduces the feeling and technique of the performer, especially in the live scene. It is well known that digital devices are difficult to provide picking dynamics.
The development of this new product required integrated technology supported by global team with experts from a wide range of fields, analogue sound engineering, signal routing control with embedded software, and precise hardware design.
Internally, the embedded software, which is a digital technology, works, but the user experience is thoroughly pursued with analogue, so the intuitive usability of the knobs that can be tweaked immediately and the familiar footing of the analogue devices that keep the pushing foot switch intact are also advantages in reducing fatigue as many things are going digitized.
LiberaToe developers have installed dual channel in every effect they design to provide multichannel functionality as like a tube amplifier, while adopting an analogue circuits that allow the players to enjoy picking sensitivity. In case of overdrive, a set of gain 1 + tone 1 + level 1 operates on the green channel and the other set of gain 2 + tone 2 + level 2 operates on the red channel. In case of overdrive having TMB tone stack, for the most important middle control, a channel with a middle knob that can be adjusted and the other channel that middle is fully fixed were adopted.
Dual Channel is not only implemented on homogeneous effects but also on heterogeneous effects. By carefully considering the number of cases in which each effect is used, for example such as using a separation or a combination of 60's vintage Fuzz and Envelope Filter, you can use the two-stage or three-stage toggle to convert the desired combination into two channels.
Therefore, in addition to the selection between A / B channels, some pedals provide functions of A-> B (in series), or A // B (in parallel).
In order to make such a variety of sounds, circuits requiring high voltages and high currents have been developed, instead of low-current 9V power. Unlike low-cost devices that typically provide 5~10mA current 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).
A foot switch is enough for handling both on/off and channel switching since the switching mechanism has been implemented by combination of relay and micro control unit. With the embedded software, the dual channel pedal takes advantage of having a few pushing behaviors. In stock mode, you turn on or off(bypass) the effect by pushing and release the foot switch immediately as usual while you can change the channel by holding the foot switch for 0.4 sec. As players may want to immediately toggle between the channels sometimes, channel mode has been prepared. Channel mode behaves oppositely, so you can change the channel by immediate short push while turn on or off with holding for 0.4sec.
The LiberaToe Pedal implements True Bypass equipped with a high quality gold-clad relay to bypass the original sound signal faithfully.
In addition, due to the nature of the pedals equipped with the control knobs, toggle switches and foot switch together, a rail has been mounted to separate the control compartment from the foot switch to prevent the control knobs or toggle switches from being unintentionally changed when the foot switch is pushed.
