for Destruction (1987) and a modded JCM800 on the subsequent albums. It can be heard on some of the Velvet Revolver material though. The Jubilee amplifiers also featured a "pull out" knob that activated a diode clipping circuit (similar to boosting the amp's input with an overdrive pedal). Other notable Jubilee users include the Black Crowes, John Frusciante (Red Hot Chili Peppers) and Alex Lifeson (Rush), who used it extensively in the recording of Rush's Clockwork Angels (2012) album. After the Jubilee year, production of the 25xx series amplifiers continued for one more year (with no internal changes), but reverted to a standard Marshall livery of black and gold. These are sometimes referred to as the JCM800 Custom amplifiers. Mid-1980s and 1990s models Competition from American amplifier companies Marshall began to see more competition from American amplifier companies such as Mesa Boogie and Soldano. Marshall then updated the JCM800 range with additional models and new features such as "channel switching", which meant that players could switch between clean and distorted tones with the push of a foot-operated switch. This feature debuted in the 2205 (50 watt) and 2210 (100 watt) series and these amplifiers contained more preamplifier gain than ever thanks to a new innovation; diode clipping. This meant a solid-state diode added additional distortion to the signal path, akin to adding a distortion pedal. As such the split channel JCM800s were the highest gain Marshalls yet built – "When they were first released, many players were shocked (some were even put off) by its bright, intense distortion – far more than any other amp of the day." While hotly criticised today among valve purists, these amps were more popular than ever, finding mass acceptance within the hard rock community and still in use today by many. The split-channel JCM800s are still used by Tom Morello (Rage Against the Machine, Audioslave) and were played exclusively by Michael Schenker (UFO) for many years. Marshall around this time began further experiments with solid-state amplifiers, which were increasingly improving in quality due to technological innovations but were still considered beginner level equipment. Regardless, solid-state product lines with the Marshall name on them were and still are a wild (if critically discounted) success for the company, allowing entry level guitarists to play the same brand of amplifier as their heroes. One particularly successful entry-level solid-state Marshall was the Lead 12/Reverb 12 combo series, which
