My fx chain is bass->comp->od->Ibanez weeping demon wah->behringer BDI21->combo. Compression and BDI21 always on. The thing is, when I want to use the wah, i have to turn off the bdi21 'cos it makes the wah a lot weaker. I really like the bdi21 with the clean sound, but now i have to bypass it at every song if i wanna add a little wah in that song, even if the wah portion only last 15 seconds, since i don't have an extra foot to switch the bdi21 on and off. i thought this behringer stuff is supposed to be a copy of samsamp bddi, are you guys with the real samsamp thing experience some similar problem or it just i get what i paid for?
