The DSL100H has two gain channels to produce that legendary Marshall sound with rich functionality for those who require flexibility and unquestionable quality. The amp can move between two sounds within each gain channel, so that players can create and release their personality through sound. There are two master volume functions so you can bring your solo to the forefront. The DSL100 can be easily taken from the bedroom, to the studio onto a gig using the five available speaker outputs, it also has the ability to record and a standby function for silent recording. Using the individual reverb for the two footswitchable gain channels, FX loop and tone shift controls you can experiment with your style. The DSL100 can be used in many environments with confidence as the power can be reduced from 100w to 50w without affecting the quality. For those more demanding players, the amps features can be controlled using any MIDI equipment, so you can play this amp and different MIDI equipment at any one time.
