Have a pedal that can take an expression input, but don't want or have room for an expression pedal? Checkout our Expression Box! It's a simple potentiometer knob connected to a TRS jack, ready to plugin to your pedal and control <whatever is controlled by the expression jack>.
We use high quality Alpha potentiometers in our box, along with a metal knob with marking indicator and switchcraft TRS jacks.
Want different knob colors? No worry, these are 1/4″ smooth shaft pots and you can pickup your own knob colors from places like LoveMySwitches and GuitarPedalParts.
As of this writing (May 14th, 2023), we stock/use a linear-curve 10k POT for these builds as it's a pretty universal value, and the linear curve is what people expect. If you want or think you need something different, just reach out! We'll happily get other values coming or chat through what you're working with.
