JMP79

The JMP79 is inspired by Lawrence Petross's own 1979 British stack, faithfully recreating the Marshall JMP preamp character in pedal format. The full amp-style control layout includes Preamp, Master, Bass, Middle, Treble, and Presence knobs.

A 3-position Bright cap switch lets you tweak the high-end bite to match your rig: from dark and thick to open and cutting. The classic Marshall preamp circuit delivers everything from warm crunch to full-on late-70s roar, responding dynamically to your playing.

Soft-touch true bypass with last-state memory. 9V DC, 20mA, center-negative. 4.5" x 2.375" x 2", 8 oz.
