Two designs and two versions to choose from!

Expression Pedal [$39]:

Plug this into any other pedal with an expression jack to get remote control of that pedal. 

Volume Control / Expression Combo [$59]: 

The combo version of this can be used as either an expression or a volume pedal (not simultaneously).

Use the slider in your series effect loop to get fully-cranked tube amp sounds at polite volumes. Or put it in your pedal chain to knock off a few dB. This is like the popular little black Amp Box.
