...If you get a MHsig, and want to put a control plate on it, where would be the best place to get one to fit? Or would you buy a blank one and cut it yourself? Thanks for your replies!
I'm assuming you mean Mark Hoppus's bass

Umm you could use a standard jazz one and ignore the extra hole? If that's a problem, Fender might make custom ones for that bass/any other basses with that knob config i guess..

...and the bassist comes up to the EQ and moves all the sliders into the typical smiley face pattern and in a really thick Jamaican accent said "you can't have de bass without de smiley face"
