Marshall 

2000 JCM900 – 4100 Dual Reverb Hi Gain - 240v

Fully Serviced

Serial Number: M-2000-04-0492-A

This 2000 JCM900 Model 4100 delivers the unmistakable Marshall roar, offering everything from punchy cleans to saturated high-gain tones that defined countless rock and metal recordings throughout the 1990s and beyond.

This example has been upgraded with a Belton Digi-Log reverb module, replacing the original spring reverb tank. The result is a quieter, more reliable reverb circuit with a smooth, spacious ambience while retaining the character of the original design.

The amplifier is fitted with a matched quartet of Russian-made SOVTEK 5881/6L6WGC output valves, providing excellent reliability, strong low-end response, and the tight, focused attack that many players favour in JCM900 amplifiers. The dual-channel layout, series effects loop, presence control and footswitchable gain structure make it an incredibly versatile workhorse for both stage and studio use.

The amp is in very good condition for its age with some minor snags/scuffs to the tolex and has been fully tested and serviced where required to ensure dependable performance.

A great opportunity to own a sought-after UK-built Marshall that combines classic JCM900 aggression with a worthwhile reverb upgrade and quality Russian valve set.
