Marshall JCM800 50W MKII Head from Indigo Ranch! (Vintage)
The head was recently serviced here in the shop. This JCM sounds every bit like it should that crunchy 80’s Marshall tone with an incredible history while it was a Richard Kaplans Indigo Ranch in Malibu CA. When we received the collection the head had the LA Metal Mod. We didn’t find it very useful. The gain attenuator added considerable noise so we elected to remove it and put the amp back to stock. It improved the tone considerably.
About the Amp:
This is an original Marshall JCM800 50W MKII Model 2204 with Master Volume. Its an original USA model with 6550 power tubes.
The JCM 800 series was introduced in 1981. Although models 2203 and 2204 had been in production since 1975, they were reintroduced as JCM800 amplifiers in ’81. The JCM800 amplifiers became a staple of 1980s hard rock and heavy metal bands.
These were the second series of Marshalls equipped with a master volume, which allowed for more distortion at lower volumes. The JCM800 is considered a “hot” amplifier because it has more gain stages than comparable amplifiers, and in “lead” mode, in the “high” input, an extra triode provides extra gain to the pre-amplifier, which really added to the highly driven rock sound.
