65Amps Colour Boost Rangemaster



Classic '60s and '70s Germanium voice without all the wildness and noise of those old pedals.

The Colour Boost by 65Amps is a fantastic evolution of one of our favorite pedals from the 1960s - the Germanium Treble Booster. The Colour Boost recreates the Holy Grail tones of '60s Germanium pedals but with enhancements derived from 65amps diligent, decade long research into components, build quality and endless pursuit of improvement.

The Colour Boost will surprise you with its modern attention to build quality, noise floors and sensitivity, all the while delivering the classic sounds you’ve sought for decades. This classic treble booster design offers two distinct features – classic Germanium distortion when pushed and the elusive “Ticket to Ride” clean tone when your guitar volume is rolled back. There’s no better way to the British Invasion super chime that is so hard to nail - The Colour Boost hits it perfectly. In addition to the original treble booster design, 65 has added a four-position voicing knob that utilizes the premium coupling capacitors from SoZo that 65 uses in all their amps.

Made with Premium Germanium transistors and amp parts, not pedal parts, the Colour Boost is a step forward in the modernization and improvement of classic designs. Utilizing the same amp parts used in all 65amps, instead of pedal parts, adds elements of tone, dynamics and quality that makes the Colour Boost a typically overbuilt 65 product.
