The Marshall DSL100HR is 100 watts of pure tube power! Driven by four EL34 power tubes and four ECC8s preamp tubes, this amp delivers that classic Marshall tone. The power can be reduced to down to 50 watts for practice or smaller venues. There are two channels - Ultra gain and Classic gain - and a single EQ section for voicing. Each channel has its own reverb level control. There are two separate Master volume controls so you can have one set for rhythm and a the other set for solo volumes. There are plenty of inputs and outputs, a 1/4" input plus a 3.5mm Aux in and MIDI input. The included footswitch has a channel switch and FX loop switch. If you're looking for further control, a 6-button footswitch is available(separately) for controlling each channel independently, switching between the Master volumes and turning the FX loop on/off.
