jdm_tonemaster_blackDec 1st, 2016 – the Tonemaster now has a sexy black finish with white silkscreened graphics. Ooh-la-la!

New Features

The JDM “Tonemaster” now has a “pregain cut” switch. This reduces the intense gain of the Tonebender Fuzz side without having to roll back your guitar volume. The pregain cut also makes the tone more like an overdrive; somewhat smoother, but with the Tonebender character through and through. With the pregain cut off, you have the full gain and fuzzier texture as demonstrated in the video.

About The JDM Tonemaster

The “Tonemaster” is our flagship guitar pedal; a combination Rangemaster-style treble booster and Tonebender-style fuzz. The combination of the two offers an impressive palette of sounds. You can create everything from a mild and creamy boost/overdrive tones to sizzling tonebender fuzz, and on into stupid-ill fuzz/octave/alien ESP reception mayhem. Simply put, you will love the tones you can create with this beast.

We assemble the “Tonemaster” by hand, using vintage European and Russian Germanium transistors. Even though we use vintage PNP transistors, it is powered by a standard negative ground PSU, which means it can share a power supply with all your other pedals. Battery power is possible with a standard 9v battery (clip inside).

A set of boutique quality Rangemaster and Tonebender pedals will normally set you back $300-400, therefore, at $159.00; this is a a seriously sweet deal for two killer effects in one pedal. We cut no corners, either. By designing the circuits to fit together in one case, we have fused two killer sounding classic tones into one pedal at an awesome price.


We ship worldwide and shipping included in the order price.
Our pedals are handmade, tuned, and each pedal is tested and tweaked for optimal tone (transistor selection is key).
The “JDM Fuzz – Boost” Features:

  • True bypass switching
  • “Rangemaster” and “Tonebender” circuits separately switchable
  • “Rangemaster” circuit includes Boost and EQ knobs – EQ knob allows you to dial in a classic treble boost, a full-range boost, and varying degrees in between.
  • “Tonebender” circuit includes Fuzz, Bias, and Volume (Output) for an incredible range of fuzz sounds from mild and creamy to just plain rude. Remember to lower your guitar volume a tad for maximum “fuzz” reactivity! Classic tones from searing fuzz to tight overdrive and chunky distortion.
  • All Germanium transistors – A combination of selected Russian Military and Vintage European transistors is selected for each unit. No cutting corners – every unit is fine tuned by ear.
  • The pedal can be powered by 9v battery or standard center-negative power supply (not included).

Reviews of the JDM “Tonemaster”

We’ve shipped many of these pedals, and almost everyone raves about not only the tone, but the variety of tones. Two customers have bought a second one because they feared having it stolen or losing it and being without their new favorite tone. But don’t only take our word for it – here’s some feedback from eBay and Reverb.com:

Some More Information

In this video, Sasha runs through some tones on a few of our fuzz pedals – he has a light touch and great phrasing – our pedals do doom and stoner as well as blues and soul!

      Hey Guy!
      I had a friend do a new design, but the old face is still peeking around in the shop! If you’d like one just order up and send me a note that you want the old face,
