Line 6 Original based on a Hot-rodded Marshall® JCM® 800.


line 6 original amp

Hot rodding would usually entail internal modifications to the amplifier.
This could just be changing the odd resistor/pot/cap value to change drive levels, tone etc…

Or it could actually be a change to the signal path itself, such as adding and extra gain stage or wiring two different inputs in parallel on older Marshall amps. Marshall with extra gain mod.

The original intent of the term “modded Marshall’ was to achieve the added gain without resorting to a pedal. For instance GnR album Appetite for Destruction, was recorded with a Hot Rodded JCM 800.

Brit 2204

Based on the Marshall® JCM-800



As Marshall amplifiers evolved through the course of the ’80s, the JCM-800 (1981-’90) came to stand out as the new flagship of the range. While the 2210 version—previously modeled by Line 6—was enjoyed by many for its 100 watts of power and two foot switchable channels, the 2204 50-watt EL34 came to be known as the flag-bearer of classic Marshall tone.

With its one, dual-input channel, added versatility of its Pre-Amp Volume and Marshall’s new Master Volume control, the JCM-800 2204 was otherwise not a stone’s throw from the hallowed “plexi” and “metal” panel 1987 Lead Models of the late ’60s and early ’70s, although its front-end gain could be tapped more easily without blowing your head off.

Cranked through a closed-back 4×12” with Celestion® G12T-75 speakers, this is the pure sound of ’80s rock, the amp that propelled countless hits from that decade and beyond.

Turn to this Amp Model to conjure up tones of the coveted JCM 800, one of Marshall’s most universally acclaimed modern amps. This updated version of the Plexi continued Marshall’s heritage with added gain and edge for a new generation of rock guitarists. One of the biggest differences here is that the tone controls are located after the preamp tubes.

Turn up Master Volume. Try with a low-gain TS808 or Tube Drive.
The real amp is too bright, you can adjust the various tone controls and parameters to reduce the brightness to your tastes presence normally way down. They are designed to be run loud and the brightness decreases as the MV is increased. Designed to get their character from power amp distortion. If you don’t push the power amp all you are hearing is the preamp which is voiced to be trebly. The power amp then compresses the highs and the sound gets fatter, but MV too high and will get muddy.
The sound of 80’s hair metal, treble boosting amplifies the upper frequencies, however, that treble boosting helps the sound cut.
