Expression Box Switched

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 TS jack, ready to plugin to your pedal and control <whatever is controlled by the expression jack>. This new switched version ALSO contains a switched TS jack for you to plug an expression pedal into! If you plugin an expression pedal, that will be used; If you do NOT plug anything into that input, the knob will be used.

We use high quality Alpha potentiometers in our box, along with a metal knob with marking indicator and switchcraft TRS jacks.  The knob color will basically be whatever I have in-stock/available at the moment, although you are welcome to put a note at checkout specifying any colors in order of preference and I'll try to use one of them.

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.
