Product Description ● This is a self-made 2-in-1 effects unit, inspired by the fuzz factory circuit, with an added booster. ● Germanium transistors are used (the model number varies depending on the shipment as it is a designated transistor of our workshop, so you cannot specify it). 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 solves the FF-series problem of unwanted oscillation when the effect pedal is stepped on heavily and the stab knob shifts slightly. Furthermore, you can enjoy switching the oscillation by setting it to intentionally oscillate and clicking this toggle. ● The order is fuzz factory on the guitar side and booster on the amp side. ● Of course, the booster can also be used alone. ● It is handmade with hand wiring on a universal board. ● 9V battery can be used. ● A 9V center-negative adapter can be used. ● φ5mm high-brightness blue LED is used. ● True bypass. ● The size of the aluminum case is 92 x 119 x 34 (height) mm. ※ Returns are not accepted except for initial operational defects. ※ This is made only as a reference, so we do not use exactly the same parts. Therefore, if you want to get 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 check it against the shipping records and repair it free of charge within six months (however, you will be responsible for the shipping costs). ● Price includes shipping.
