The Derringer Fuzz is based on the famous Univox Super-Fuzz circuit—an incredible, six-silicon transistor fuzzy beast of a pedal perfect for bass and guitar. This pedal was named after Derringer, a user on the FSB forum whose suggested modifications to the original Super-Fuzz circuit, helped craft the sound and tonal options of this classic fuzz.

In addition to the original’s controls—Balance and Expander—the Derringer includes a Tone knob which continuously pans between two filter settings, and a Brutal knob, which controls the amount of signal compression towards the end of the circuit, aided by a pair of soft-clipping, asymmetrical diodes. The Derringer also includes several filtering components at its input and output gain stages, which are responsible for shaping the frequency response of the signal, giving bassists tons of booming low-end. At high saturation levels, the octave-up capabilities for which the original Super-Fuzz is known become even more pronounced.

This pedal comes highly recommended to multi-instrumentalists who love the flexibility of using the same pedal to power their guitar, bass, or even synth. For those who absolutely love to maximize the tweakability of their sound, the Derringer Fuzz gives a wide range of ferocious, supersaturated, warm, and gnarly fuzz.

Each Carcharias Effects pedal is hand-made by one person in his home workshop who loves making music, and making things that make music. Every purchase you make enables me to continue making more pedals, so your support is very much appreciated. That said, I take responsibility for the build quality of every pedal I make comes, and offer a 24-month warranty on each one, not covering normal wear-and-tear or abuse.

All the PCBs that I sell on this site were designed personally by me, but the fabrication is outsourced to third-party PCB fabrication services. Once they are designed, I order them in relatively small batches. I personally test every batch that I receive; however, as I am a strong believer in minimizing waste, there are cases in which I may sell perfectly functioning PCBs that might have some design flaw. I take responsibility for these design flaws (if any) and will specify their fixes or workarounds in the product's specific build document.

If you should encounter any issues with your product, please feel free to reach out to me via the contact form on this website. As I am based in Israel, I understand the inconvenience added by international shipping, and so I will be happy to assist in troubleshooting with you any problems before resorting to international shipping in case a repair needs to be made.
