Description

The JCM900 4100 was the next evolutionary step on from the JCM800™ Series. This is a precise re-issue of the JCM900 4100, first launched in the early 1990s. This high gain, dual Reverb, all-valve 100 Watt head is still a players’ favourite. Known for its tone and workhorse roadworthiness, the JCM900 4100 has many fans due to its feature set and versatility.

Channel A is voiced to be sparklingly clean on lower gain settings, building to a raunchy crunch when driven harder. Channel B takes the gain higher producing tones from silky smooth distortion to searing, saturated scream.

The JCM900 4100 is equipped with a series FX Loop with its own Level control for use with rack FX or stomp boxes.

Reverb

A reverb pedal is like the rich sauce that ties every flavour on the plate into one smooth experience. It adds depth, warmth, and atmosphere — the sonic equivalent of a perfectly reduced glaze that lingers on the tongue. Whether you’re after the subtle ambience of a cosy café (spring or plate reverb) or the grand echoes of a cathedral (hall or shimmer reverb), this is where your tone breathes and expands. A touch of reverb can turn a dry sound into something lush and inviting — but pour on too much, and it’s all you can taste. Used with finesse, it’s the finishing touch that transforms your tone from plain to unforgettable.
