About This Listing

Guitarsystems TrebleTool Junior s/n 026 in excellent condition. Thoroughly tested and in full working order.

Handcrafted by nerdy elfs in the Netherlands.

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‘s. 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.

NOS Germanium transistor - a New Old Stock Germanium transistor with the correct parameters for gain, leakage current and frequency

Gain control - adjust the effect output volume

Continuous variable range control (T.M.F.) - dial in the amount of low end with a specific guitar type or pickup combination

Tone control - adjust the amount of treble for a specific amplifier

The PaulSwitch ® - robust true bypass footswitch to switch effect on/off & to avoid tone sucking in bypass operation

External power supply - (noise reduced) providing the option to use an external power supply without inducing noise or changing the character of the sound.

Pre warning Battery low indication - giving the opportunity to changeover batteries before the effect stops working

Reverse and over voltage protection - to protect the sensitive germanium transistor and keeping the pedal running for many years to come

Radio Frequency Interference (RFI) suppression - avoiding radio signal reception when using high gain setting in combination with turning down guitar volume
