It's less costly than the original Sans Amp, and it's even easier to set up. So the folks at Tech 21 must have compromised on sound quality, right? Not as far as we can tell! GT2 purrs and screams with the same kind of fat, warm, glowing-glass sounds heard in the original, but cost-effective manufacturing brought the price down. You select amp type, modification, and mic placement. Find the tone you want using high and low EQ, set your level, dial up distortion with the drive knob, then hit the "on" switch. A truckload of tube amps in a pedal!
