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, Brian May and Tony Iommi.
An original Dallas Rangemaster
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.
"The flexible Treble Booster"
FEATURES (* extra features compared with junior)
NOS Germanium transistor - a New Old Stock Germanium transistor with the correct parameters for gain, leakage current and frequency
* Impedance Conversion Interface (on/off) - converting an active input signal (EMG pickups, Wireless system) to a signal suited for the TrebleTool and thus retaining the character of the effect
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
