Product Description ● This is a MOD pedal based on the Axis Fuzz circuit, with added features such as a bias knob. It's a 2-in-1 effects unit created by adding a booster. ● The center bias knob allows for adjustment from low-volume fuzz to clean fuzz. ● An internal trimmer is also included, allowing for adjustment of the "spluttering" sound. ● Hand-wired construction on a universal circuit board. ● The signal chain is fuzz on the guitar side and booster on the amp side. ● Of course, the booster can be used on its own. ● Operates on a 9V battery. ● Can be powered by a 9V center-negative adapter. ● Features a φ5mm high-brightness blue LED. ● True bypass. ● The aluminum case dimensions are 92 x 119 x 34 (height) mm. ● EBK is a name used only for auctions.
