The DSL15H from Marshall Amplification is a 6-valve head amplifier for electric guitar, featuring two channels with separate volume and gain controls and a comprehensive equalization section. The Dual Super Lead (DSL) offers two channels, Classic Gain and Ultra Gain, to provide a wide tonal palette of classic Marshall tones.
Classic Gain takes you from a shimmering, harmonic-enhanced clean to a 1959-style crunch when the Gain control is cranked, while the Ultra Gain takes you into the world of modern, high-gain tone. Both channels share a passive three-band EQ with controls for bass, mid, and treble. The Tone-Shift button provides a mid-scoop that is synonymous with modern metal, especially when combined with higher gain settings.
The amp's power section features a control for Deep button, which adds a fixed, resonant bass boost without adding mud, while the Presence control adds high end sparkle. Additionally, the amp includes a Pentode/Triode switch, which halves the power from 15W to 7.5W. The DSL15H ships with a power cord and a footswitch for Classic Gain/Ultra Gain channel selection.
