Range Master Germanium Treble Boost
NEW VERSION IS AVAILABLE - This version has been retired.
The Dallas Range Master. Bedrock of so many classic tones. Beautiful germanium treble boost. The originals used OC44 transistors, but they're as rare as a coat on a night out in Newcastle, so we'll offer a selection of cans as and when we have them available. They'll all offer their own unique character to this little gem, so why not try a few to see which you prefer? Now also availalble with no transistor in case you've sourced your own little beauty.
PNP (positive ground supply):
- 2N404
- AC128
If you can source a NPN transistor with low enough leakage you can make yourself a negative-ground version, but here at FDHQ we're all out.
Board-mounted pot for minimal wiring and easy enclosure mounting.
Multimeter recommended for optimal biasing, but it can be done by ear.
Combine with a Power Pump kit if you want to power your PNP configuration on your standard polarity daisy chain.
If you want the PCB without parts there's a link for that at the bottom of the page.
Partial kit: PCB, all board-mounted components, pots.
Full kit: As above, plus footswitch and appropriate daughterboard/components for your selected bypass type (see Downloads section for details of those), jack sockets, DC socket, battery snap, hook-up wire, LED.
Enclosure (pre-drilled) is available as an option with full kits, and can take a battery if desired with footswitch positioned 22mm higher, closer to the controls. Knobs are not included.
