Tim Pierce: „It makes your amp sound like it just was re-tubed“

 

Dallas Rangemaster History

The main concept of the TrebleTool Junior© is based on the Dallas

Rangemaster, a germanium transistor based treble booster developed around 1965 in London, UK by a company called John E.

Dallas & Sons Limited. The Rangemaster was used to drive Tube

Amplifiers into saturation because (high) gain Tube Amplifiers were not available during the 60‘ties. Famous guitar players who created their unique sound with a treblebooster are: Rory Gallagher, Eric Clapton, Ritchie Blackmore, David Gilmour, Bryan May and Tony Iommi.

Technology concept

Like the original Rangemaster, the core of the TrebleTool Junior©

is a single stage transistor preamplifier based on a selected NOS

germanium transistor with the correct technical specifications

combined with a high pass filter. It creates a transparent dynamic

sound that will cut through the mix without being perceived as

over the hill. The TrebleTool Junior© is basically a Rangemaster

extended with features that increase operating flexibility and

solve short comings of the original design but do not change the

original Rangemaster sound character.
