At two height units, we have housed the preamp section of our legendary Special Edition head here. Each of the four channels (Clean, Crunch, Lead 1, Lead 2) can be operated in Classic and Modern mode, in addition there are two different gain structures per channel, making a total of 16 sounds! With Contour, Bright, Ultra Bright, Mid Edge and Mega Low Punch, you have more sound-shaping tools at your fingertips to make every sound imaginable. The spectrum ranges from crystal clear clean sounds, authentic blues crunch to classic rock and modern metal thunderstorms. As befits a neat rack preamp, the outputs and the effect loop are stereo-based, and you can store all your sound creations in 128 MIDI slots - the golden era of the racks sends their regards! Get ready for Rack’n’Roll!
