The Fuzzhausen is a limited-edition fuzz pedal from Oneder Effects. The maker describes it as a fuzz with two footswitches and no knobs, and this one comes in a limited edition Black Sparkle enclosure1.
Controls and layout
The Fuzzhausen keeps its front panel deliberately bare: two footswitches and no knobs1. There are no potentiometers to set, so the pedal is operated entirely by switching. The jacks are top-mounted, which helps the pedal sit close to its neighbors on a crowded board1.
Circuit and relation to the Heckboy
The Fuzzhausen's layout is unusual among fuzz pedals: Oneder Effects specifies two footswitches and no knobs, so the player switches between settings rather than adjusting them by hand1. The pedal ships in a limited edition Black Sparkle enclosure1.
The Fuzzhausen is limited to 25 units. Once the run is gone, Oneder Effects gives no indication of another production run1.
Power requirements
The Fuzzhausen is strict about power. Oneder Effects states that the pedal only accepts 9V center negative isolated power, and that no battery can be used. A power supply is not included, so you will need to supply your own1.
The maker is direct about why the supply matters: "Cheap wall-warts will lead to unwanted noise." An isolated supply, where each output feeds one pedal separately, is what Oneder Effects asks for here1.
