Freakishly Flexible Fuzz
**UPDATE: Feb5th, 2025 – The Union Fuzz now has switches for both Q1 (first transistor) and Q2 (second transistor) as well as a hi/lo gain switch.
Silicon and germanium transistors create different shades of harmonically rich fuzz, and the Union Fuzz takes the classic “Fuzzface” circuit to another level of flexibility and reactivity.
Select between silicon or germanium transistors for both positions (“Q1” and “Q2”) as well as a “hi/lo” gain switch for a lower classic fuzz gain structure, 60’s style, or a higher gain 70’s style response.
In a two-transistor fuzz, the first stage provides the “drive” to the second transistor, but also affects the way your guitar interacts with the pedal. Silicon in “Q1” will drive the “Q2” transistor harder for a fuzzier tone, and is also brighter. Germanium Q1 creates a warmer tone that also cleans up even better with the guitar’s volume knob. In the Q2 position, go for a bright, cutting silicon character, or a thick and gooey germanium response. Each of the four possible combinations will be sure to inspire new ideas and fit into the mix in unique ways.
Additionally, the “bias” control dials in the harmonic content and sustain character. Lower settings are both more gated/sticky sounding, as well as adding more harmonics. Increase the bias control shapes a smoother, more overdrive-like tone.
Under The Hood
The JDM Union Fuzz features:
– Powder coated and UV-printed finish
– Lumberg Jacks, Alpha Potentiometers, and Dailywell heavy duty 100,000 cycle switches
– Modern low-noise silicon and carefully selected vintage germanium transistors.
– The pedal functions on Standard +9vDC, center negative power supplies (aka Boss Style) or a standard 9v block battery. We use a very low power red LED to help extend battery life, and disconnecting the input jack also fully disconnects the battery.
If you have requests for customizing the pedal to your taste, just let us know – we take custom orders all the time, and customers have been thrilled with our custom pedals. “Like” us on Facebook and check out our other pedals, custom designs, and the monthly “Guitar Journal” guitar lessons, too.
Return Policy
If you’re not satisfied with any JDM Pedal, you can return within 14 days for a refund (minus shipping and payment processing costs, which Paypal does not refund to us 🙁 If you encounter any functional problems with a pedal at any time just contact us! Since we use vintage transistors, it is possible that a transistor can fail, as rare as that is, and we’ll always do what it takes to get your beloved fuzz machine growling again.
