Controllable effect units
This is a list of effects pedals and devices that have an expression jack, sometimes called a control port or foot controller port. An effect unit may allow expression control over a single parameter or multiple parameters. Where expression control is over a single parameter, the parameter is listed. Where expression control is over most or all effects parameters as is true with many multi-effect units, the parameter is listed as 'Multi' or "All parameters".
