Any opinions on the newer Dr. Swamp? I simply cannot live without mine. My drive pedal journey started with the MXR Distortion III (too muddy), the Marshall Jackhammer (muddy again and too much faff).... I saw an ad for the Mean Machine and discovered the dual drive thing, but it was waaaaay out of my price ranged at £200 .... but that same day I saw a Dr Swamp on sale for £50 and snapped it up. I love it and it hasn't left my board. I've compared it with xCotic BB+, zen drive, JHS thunder bird and Wampler Dual Drive and the Swamp is still my favourite and better to my ears. I even bought a Bogner Ecstasy Red as they are meant to be one of the very best (they are) and the Swamp still rules. The flip flop switching is great when I'm gigging a bit drunk as many of the others I mentioned are drive and boost, and some even change direction!!
