Product Description ● Modified and built based on the circuit of the Fuzz Factory. ● Equipped with silicon transistors (the model number varies with each shipment as it's a designated transistor from our workshop, so the specific transistor used is unknown beforehand. Germanium versions are also available. ● The toggle switch on the fuzz is an oscillation cut switch. This solves the FF-type problem of unwanted oscillation when stomping on the effect aggressively, even if you don't want it to oscillate because the stab knob has moved slightly. Furthermore, you can enjoy switching the oscillation by intentionally setting it to oscillate and toggling this switch. ● Hand-wired on a universal circuit board. ● 9V battery use is OK. ● A 9V center-negative adapter can be used. ● Uses a φ5mm high-brightness blue LED. ● True bypass. ● The aluminum case size is 60 x 112 x 31 (height) mm. ※ Returns are not accepted except for initial operational defects. ※ This is a product made for reference, and does not use the exact same parts. Therefore, if you want the exact same sound, we recommend purchasing the actual unit. ● EBK is a name used only for auctions. In our main business, we adjust, create, and adjust guitar equipment such as amplifiers and effectors specializing in blues-related gear. The number of units produced has exceeded 4000 (as of August 6, 2024), and many professional musicians use our products. ● Six-month warranty: We manage customer records, so if a failure occurs under normal use, we will compare it with the shipping records and repair it free of charge within six months. (However, you will be responsible for the shipping costs.) ● Price includes shipping.
