Abby Active A/B/Y

Abby Active A/B/Y


ABBY is a powerful active A/B/Y switcher. It has a useful phase inverter toggle switch on Output B. When using 2 amps together that are out of phase a simple flick of the switch flips the phase of Output B 180°- problem solved. 

  • Product information

    This active A/B/Y pedal takes your input signal and splits it in 2 with a dedicated buffer for each channel. You can send the signals either one at a time (A/B mode) or both a the same time (Y mode). The phase on Output B can be inverted 180°, this means you can use 2 amps that are out of phase together. The circuit is active, so there's no loss in signal strength as it's not simply split in 2- each channel has its own buffer. This greatly reduces noise, crosstalk and problems with impedance or signal loading that can cause high end loss and overall tone loss. 
    This pedal can be the start of a wet/dry stereo pedalboard. It can also be useful to get a 2 channel setup on a single amp- on channel 1 (OUT A) you can put a distortion pedal or even a completely different pedalboard and on channel 2 (OUT B) have a different signal chain to switch between. 

  • Tech specs

    Current draw: Max 7mA at 9V
    Impedance: 1.1MΩ input impedance, OUT A and OUT B 150Ω
    Power: This pedal can be powered by a 9V battery or a 9V DC adapter (2.1mm center negative). Unplug the IN jack to preserve battery when not using pedal. When a DC jack is inserted into the DC plug the battery is disconnected from the circuit.
    Size, weight: (LxWxH) 7.1 x 11.3 x 5cm, 225g without battery

    Operation: A/B footswitch: changes between Output A and B. Y footswitch: both outputs are on at the same time. Phase switch: Invert phase on Output B.
