FleetingSpider

These are the various treble booster pedals that I built after doing an analysis of the Dallas Rangemaster circuit to make it capable of using modern pedal board power and to reduce the output noise.

This is an enhanced version of a germanium transistor treble booster based on the Dallas Rangemaster.


This version incorporates modifications to allow the operation from standard negative ground pedal board power supplies while minimising output noise. The design retains the original frequency response and tonal qualities but has selectable input capacitors to allow additional frequency responses if required.

This is another enhanced version of a germanium transistor treble booster based on the Dallas Rangemaster.


This version incorporates the same modifications as the one above but also includes an external bias control to allow s the distortion to be adjusted if required.
