The Marshall DSL100H tube guitar amp head has footswitchable Classic Gain and Ultra channels, each boasting two modes - Clean/Crunch and Lead 1/Lead 2 respectively. These will take you from Plexi-style, pristine clean to JCM800 snarl, hot-rodded 2203, high gain lead and all points in-between. The flexibility of the shared 5-way EQ (Treble, Middle, Bass, Resonance and Presence) section is increased further by a Mid-Shift button - perfect for modern metal brutality. A series FX loop on the rear panel (bypassable via an on/off switch) adds to the DSL100H's professional flexibility, as does the Pentode (Full Power)/Triode (Half Power) switch which drops the power-amp's output to 50-Watts. It also changes the amp's tonal character as Triode mode produces a smoother, less aggressive sound.. Included accessories: Other(FOOT SWITCH).
