The Uncle 125 Bass Overdrive (or simply “The Uncle”) is Carcharias Effects’ boomier take on the classic op-amp gain topology—specially modified with bassists in mind. Its features and modes provide a wide range of tonal options, giving you everything from crunchy distortion, to subtle overdrive, to dirty boost.
With the clipping diode switch, you can select between Germanium diodes or LEDs. Guitarists and bassists alike can enjoy the sizzling overdrive of the Germanium diodes. The boomier, bassier, LED-driven overdrive gives the bass an undeniable presence, with crispy and brittle highs perfect for pick attacks. Turn up the gain (but beware of the output volume!) and take your bass to Russian muff-like overdrive territory.
The Blend knob allows you to control how much of the distorted Uncle signal is mixed in with your dry signal, letting bassists preserve their clean signal while dialing in the dirt (great for Germanium diode mode). The Uncle is also excellent in gain-stacking setups, e.g., into a Rat, or a Model T.
Each pedal in this first run of Uncles was entirely hand-made—so each one of them is unique! This means that each circuit board was soldered and tested, each enclosure hand-sanded, polished, and finished, and each bolt was meticulously fastened by one person in his home workshop, in his free time.

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.
