I got one of these today. The low gain setting is very useful for me - haven’t taken it to a gig, but I think it’ll work fine.
The high gain setting (even dialed back as much as you can with the internal trim pot) is, however, completely useless to me. The possibility that that sound could erupt due to a foot stomping error (the switches are very close together, and I have big wide feet) means that the pedal, out of the box, is a liability that I can’t use.
So…. I’ve hot wired mine so the high gain mode is not accessible - a non functioning switch is far better than one that turns on a godawful (to my ears) mode.
