Have a pedal that can take an expression input, but don't want or have room for an expression pedal? Checkout our new Expression Roller! 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>.
Perfect for compact foot-control of anything that accepts an expression input. The knob itself contains no markings, so you can mark/tape/paint/do-whatever you'd like
We 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.
*These knobs do not have any marking, and while we are working to find some with markings, markers/tape work perfectly well to mark it however you want!
Works well on a Boss DD200!
great product, way better than the last exp roller i had from a different manufacturer. very good quality for the price
Works great!
Works like a charm! Great build quality. FYI, I use this instead of an expression pedal to control the feedback (“intensity”) on the Boss RE-20 Space Echo.
