Marshall PEDL-10024 JH-1 Jackhammer (Ultra Gain Overdrive)

Switch between open Overdrive (classic Marshall crunch) and saturated Distortion (intense lead gain), then sculpt your tone with Gain, Volume, Bass, Treble, plus a powerful Contour section featuring Scooping and Frequency controls. Built in a rugged metal chassis with passive bypass, it offers authentic valve-stack aggression and sustain.
