Pump'd Up Rangemaster Plus - P.U.R.P.
Classic PNP Circuit / Neg.Tip Power Supply
This is our revision of a vintage favorite! We have studied many versions of this classic circuit, and gave it the royal GuitarPCB.com treatment. Included in this version is a charge pump, which allows you to use a vintage Germanium PNP transistor and still share power with your other standard negative-ground pedals, or combine this with another circuit in the same enclosure and share a power source.
The original Rangemaster was a treble booster. This build incorporates (3) different tonal selections. The first will give you classic Rangemaster treble boost. The second setting boosts highs and mids. The third setting boosts the full tonal tonal range of a guitar, or “band pass” setting. With size in mind, the circuit board was designed to fit in a small, 1590A enclosure. The (3) tonal selections are made with a small SPDT On-Off-On switch, again, with the 1590A enclosure in mind for those who like tiny pedals.

Here is a Photo essay I did in PDF format to give you some ideas on how to work with both sides of circuit boards to allow for fitting your populated board into tighter spaces.
Some ideas will apply to other builds such as the P.U.R.P. or the SHO 'Nuff etc...
Always remember orientation and more importantly you are only limited by your own imagination!
Circuit will fit a 1590A Enclosure.
Must Have Accessories
Please note your build version located on the board.
If it is a new Version 2.1c you will need the new Build Document.
All that is new is that the board was changed so that PNP transistors will not require you to bend the leg for appropriate orientation. No difference otherwise.
If you have the previouse Version 2, then download the Build Document in the first thread.

See our Home Page for all Guides!
Check the Layout Gallery section of the Forum and find your project before building.
Troubleshoot threads must have pictures and voltages.
All builds are 100% verified. Be sure to use Genuine Transistors and IC's
Any serious builder should have an Audio Probe to diagnose problems quickly.
