I don't know if there has already been a thread about this. I couldn't find one with the search function. Criteria: Price not an issue Can be head or combo Three or more channels/modes available via footswitch Must be able to get nice and clean, provide good rhythm crunch and a nice higher gain lead tone. Post why you think it's the best No pissing wars. Everyone is entitled to their opinions I'll start off with ones I've owned and liked: Hughes & Kettner Duotone: Two channels but it had two separate master volumes foot switchable and also a foot switchable overdrive boost on the dirty channel. So you actually had 2 different clean levels, two different dirty levels and two different levels of gain for a total of 6 different sounds. Clean was nice and warm and the distortion channel had a voice that mic'd up real well in a live situation. Hughes and Kettner Triamp: All the same things I liked about the Duotone but the 6 modes you had were far more tweakable. Mesa V-twin preamp w/just about any power section: Awesome piece of back-up gear for gigging. Sounded pretty darn good just about any way I ran it. Direct, in front of a power amp, in to the return in the loop of a good tube head, as an overdrive pedal in front of a good tube head. ADA MP1: My first foray into multi-channel setups so it has a place in my heart. The secret to that thing for me was to use the tube clean channel for my rhythm tone and just crank it. Nice and brown. Then use the Tube Dist. setting for lead tones. It also had a VERY nice chorus for the clean stuff. Bogner Ecstasy 101b: I currently own this one and it's just mind boggling how many great tones are in this thing. Mine has an attenuator loop and cabinet switching capabilities. Neither of which I have explored. But I think you can have two cabs and assign each channel to which ever cab you want AND ALSO assign the attenuator to any of the three amp/cab setups you have. See? Mind boggling. Also, the blue channel in Plexi mode is really something to behold. CAE/Suhr OD-100SH: I currently also own this one. Mine is the EL34 w/Plexi OT version. Has the Power Amp Feedback and Boost dials on the back. Also a two channel amp but the foot switchable boost gives you a third mode. Right now it's edging out the Bogner for my affections but that could just be because it was the last one of the two I played. I'll probably flop back to the Bogner next week. One thing this amp has over every other one that I've owned is the clean channel. It's just the balls. Also, this amp takes pedals like none other that I've ever owned. At bedroom volumes this amp is just sick. Cranked it's even sicker!!
