Fulltone Custom Shop Ranger | Treble Booster

N.O.S Military Germanium Treble Booster

The Dallas Rangemaster was a germanium transistor-powered pedal made in the mid 1960s that was heavily used by Brian May, Tony Iommi, Rory Gallagher and many others to achieve their signature sounds.  Although sold as a treble-booster, it actually boosed the mids as well, imparting an incredibly harmonic-laden distortion and pushing valve amps to further distort.  Nowadays they sell for thousands, so it's great that Fulltone have brought it back to life with 5-extra frequency rangers, true-bypass and in a super-compact enclosure.  Michael Fuller also devised a way to allow the pedal to remain PNP (positive ground) whilst still being powered by a standard NPN (negative ground) power supply.  The Fulltone Ranger contains NOS military germanium transistors culled from Michael's own stash and tested for noise, leakage and tonal qualities by himself.  100% hand-built in California.  Wow!

Is this the greatest Rangemaster treble booster clone ever?

Here's why we think it could be:

  • Proprietary Power supply design allows this PNP (Positive to ground) Germanium pedal to be powered by any standard NPN (Negative to Ground) power supply!
  • 6-position rotary switch, 6 different sounds, including Rangemaster 1 and Rangemaster 2.
  • Sexy amber light jewel.
  • Top-mounted jacks & DC port.
  • Adjustable Transistor Bias trimmer. Want it soft? Want is hard? Want more or less chime? Just turn it and adjust by ear, there is no wrong setting.
  • It's a TINY pedal (4.75" x 2.9") yet there's a battery in it too... grab'n'go.
  • 100% Hand-Made in Los Angeles using full-size components.
