there is a gain control for each channel, there are only 2 channels and a gain knob at each channel, so no brainer...it has gain controls for each channel

^wrong

Channels 1 and 2 share pre-amp eq knobs (including gain) and channels 3 and 4 share theirs. Each channel has it's own volume, and then there's a Master A and Master B volume with global presence and depth knobs

The main problem is the presence and depth controls. You can get a wicked dirty sound on channels 3 and 4, but then your clean and crunch suffer a bit or vice versa. I've found a nice balance where I like the way all of it sounds (I don't use channel 4) by using the MXR-10 band. But if you're really picky, it might piss you off. I know a few people on this board have complained about it a lot more than I have.

i've never had any problem with the pb's shared eq, i dont think anyone really should if they'd take the time to dial it in.

I find that at bedroom volumes it's not so noticable but at gigging volumes, the presence and depth really come into play and fuck with you
