used R2R Electric Two Knob Treble Booster OC44

6 position rotary tone knob

excellent condition w/original box and contents


Every R2R Electric unit is built with a combination of New Old Stock (NOS) & vintage components recycled from 1950’s & 1960’s audio gear 

Here are the specs:  

Original Dallas Rangemaster circuit with 6 position rotary tone selector switch  

1960's Philips black glass OC44 germanium transistor

Vintage CTS, Piher, Centralab or Stackpole potentiometers  

NOS Philips/ Sprague 50uf electrolytic capacitors  

NOS 1960's Gen Inst, Sprague Vitamin Q, West-Cap, Hopkins and Kemet paper in oil input capacitors  

1963 Sprague Black Beauty output capacitor

Allen-Bradley carbon comp resistors  

True Bypass footswitch  

Switchcraft jacks  

1950's Bakelite Chickenhead knobs


*Due to the nature of this circuit, these pedals work best placed first in your signal chain. If you are using any buffered bypass pedals (ie: Boss, MXR, etc..) this pedal need to be placed before it in the signal chain. Please feel free to contact me with any questions* 

**This pedal can be powered by 9v battery (included) or with a standard Boss/One Spot style 9v power supply**

***Please note that these pedals will not work in a power daisy chain with other pedals that use a standard negative center power supply like a Boss or One Spot. It will need its own isolated power source either it’s own separate power adapter or it works well with a Voodoo Labs or similar power brick***


Each of my pedals are made with high quality vintage components, either NOS (New Old Stock) or pulled from vintage audio equipment.  

Each component is tested and matched to each pedal for optimum tone.  

Every pedal is hand built in Los Angeles, CA
