Product Description ● Modified and built based on the circuit of the Fuzz Factory. ● Equipped with germanium transistors (the model number is different for each shipment as it is a designated transistor of our workshop, so it is not possible to know in advance which transistor will be used. We also sell a silicon version that is not affected by temperature differences. ● The toggle switch on the fuzz is an oscillation cut switch. This eliminates the FF-type problem of unwanted oscillation when the effect pedal is stepped on heavily and the stab knob is slightly misaligned. Furthermore, you can enjoy switching the oscillation by setting it to intentionally oscillate and clicking this toggle. ● Hand-wired on a universal board. ● 9V battery can be used. ● A 9V center-negative adapter can be used. ● Uses 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 only a reference build, so we do not use the exact same parts. Therefore, if you want to produce the exact same sound, we recommend purchasing the actual unit. ● EBK is a name used only for auctions. In our main business, we adjust, manufacture, and adjust guitar equipment such as amplifiers and effectors specializing in blues-related equipment. 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 information, so if a failure occurs during 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.
