Expression Knob

The Expression Knob is the smallest expression “pedal”. It allows you to control a pedal’s expression without losing space on the pedalboard.

Usage examples:

  • In CBA pedals for example, with the expression knob you can change multiple parameters via the dip-switches.
  • In Blooper, you can set a modifier knob to a low value and then all the expression knob range will be the narrow range selected, adding more precision or limiting the expression knob to the desired range. Check the Blooper video for examples.

Knob is made of CNC-machined aluminum. The rest of the body is 3D-printed with resin.
