Instantly create two unique foot switchable potentiometer settings whether it be Volume, Gain, Delay, Tone, Ramp Modulation Speed or anything you can imagine.
Description
The 2 Knob Job is an incredibly useful and exciting Mod Board.
The board will allow you to use two (2) potentiometers (the Primary and an on-board trimmer) to instantly create two unique settings at the stomp of a switch whether it be Volume, Gain, Delay, Tone, Ramp Modulation Speed or anything you can imagine. All this using a very small footprint. Boutique your builds!
