Two independent analog amps with reverb, in a pedal-size box. The DSM & Humboldt Simplifier DLX is a zero-watt dual-channel stereo amplifier. Each channel has its own analog preamp with three amp types and three gain modes, followed by power amp and cabinet simulation and a multi-stage stereo reverb.
