Revolver 18

The Colorsound  Revolver 18 amplifier is based on an early 60's Marshall design - the famous Marshall (tm) 18 Watt amplifier.

It is a 1 channel amp with 2 inputs - 1 normal & 1 low.

Our modifications to the original design include:

  • Middle, Treble, Bass controls instead of a single Tone of the original design.
  • The addition of Reverb instead of the tremolo of the original design.
  • Output switch to cut the output in half so you can have 9W or 18W.
