The pedal needs an overall gain knob -- you have the ability to separately control the amount of original signal, as well as individually for both octave one and two, but not an overall volume control... which means that hitting the pedal can produce a boost in your volume which you would have to control with an external volume pedal.4) It would be nice to be able to switch between lower and higher octaves.

Volume controls aren't great, basically just use it on max all the time

As for the "cheap" plastic housing, it's ABS and I highly doubt anyone will crack it unless you are sh@t-kicking the hell out of it with a steel toed boot
