Range Master Germanium Treble Boost

Hot! Range Master Germanium Treble Boost

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 I'm offering a multitude of can options for you. They'll all offer their own unique character to this little gem, so why not try a few to see which you prefer? I'll throw in a socket in if you're buying a multi-can option for easy switching around. Now also availalble with no transistor in case you've sourced your own little beauty.

PNP (positive ground supply):

  • AC128
  • Russian 1T308B
  • Russian 1T308Б

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.

The Russian cans listed have especially low (almost zero) leakage. Sweet. In both cases they have a small paint dot on the lip of the case that indicates Emitter. Centre leg is Collector.

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.

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 only available with full kits, and will take a battery. Knobs are not included.

Difficulty: Easy

PCB size: 30 x 22mm

Knobs required: 1

Enclosure: 1590B

Direct-Connect compatible (4-way)

If you want the kit pre-built you must add the enclosure option below and select your knobs in the Components section. Check Specials for powder-coated enclosure availability.

Vintage mojo - you know you need one! 5 product stars
"Built one a while ago with an extra switch for choosing different input caps (4n7, 10nF, 27nF). This box transforms an otherwise clean-ish amp into a monster rock tone. Luckily I had an AC176 going spare, so it plays well with my daisy chain power supply. This one's a keeper. Cheers fuzzdog!" Ian - 29/10/2018
Easy build with incredible tone! 5 product stars
"I added the Charge Pumped Daugherboard for a PNP build. It was a easy build that took almost no time to put together. Like all Fuzzdog kits there is no noise. It has a great tone that is as good if not better then high priced boutique range masters." Rich S - 28/03/2017
Don't be put off by positive ground! 5 product stars
"I'll just begin by saying that this was my first positive ground effect, and I've built many effects over the years (some with pcb's from the Dog!). The normal "Boss" style of powering effects has became a habit, so this took a little thought, but it's simple really. This was my first full kit from Fuzzdog, although I've had pcb's and trannys from them in the past. The quality of everything is amazing. The sound? AWESOME! Feed it into a cooking amp, and it's probably the only pedal you will ever need! It just does SOMETHING to the notes, makes them sing! Thanks Fuzzdog!" Matt Lowe - 15/02/2017
Vintage awesomeness! 5 product stars
"Just amazing. I built this to brighten up my home made 5E3 Deluxe, which it does beautifully. Get the drive just right and it gets the first stage preamp tube (12AY7) singing like a bird. Simple and so effective. I did have a meltdown when first assembling, due to incorrect orientation of the PNP transistor. Fuzz dog HQ, were more that understanding and sent me a new set of components, which went together perfectly,me end though the fault was all mine. If you have an old valve amp and want to get it singing, this is the pedal you must have." Dave - 14/01/2017
great pedal, great support 5 product stars
"the pedal sounds great and fuzzdog's support is always faster than light! I've done many fuzzdog kits, all great kits. maybe the led-bezel could be better." giorgio - 22/10/2015
Awesome vintage sounds 5 product stars
"I just finished this pedal it sounds great. I has a real 70s vibe to it, it makes my guitar sound like Clapton's on the Rainbow Concert album." Big Dan - 07/05/2013
