I usually stay far away from this section in order to keep my bank accounts intact. Anyway, I have a couple of new amps, and I find myself in need of a boost pedal for my pedalboard. The amps are a Peavey Classic 50, and a Rivera Knucklehead. I dig the tones of both of those amps' dirty channel, but believe it or not, I don't quite get the 'sustain forever' while doing leads. They are both high gain, but not like metal amps, so it's not infinite gain. I've used an MXR micro amp in the past and liked it, but I'd like to add a pedal with a tad bit of gain to put my solos over the top and get some nice sustain going into feedback sort of thing. It may be because I try to keep a civil stage volume, and I don't quite push these amps where they need to go. Second question would be, is it okay to run such a pedal into the FX loop, or is it best before the amp? I also planned on getting a looper so I could switch the boost and delay in at the same time for soloing. I'm not sure if I could do this if one pedal is in front and the other is in the loop. Any suggestions would be greatly appreciated.
