This is a handmade pedal built point-to-point, based on the circuit of the EarthQuaker Devices Tone Job. It's an active circuit equalizer and booster. It features a 3-band EQ with a Baxandall tone circuit using a JFET input op-amp, with the addition of a Mid control. This type of circuit (though with different component values) is also incorporated in the company's Talons and JHS Charlie Brown. Compared to the Talons, the Mid control is more refined and easier to use, and it seems to be favored by bassists as well as guitarists. It supports input voltages up to 18V. 125B size (approx.) 122mm x 66mm x 39.5mm All potentiometers are fitted with caps to prevent dust from entering. Please use a DC 9V-18V center-negative power supply or a 9V battery. There may be scratches or paint unevenness due to the manufacturing or use process. Also, please be aware that continuous contact with rubber materials may cause the paint film to dissolve. True bypass. If there are any critical initial defects, such as the power not turning on, please notify us within one week. #HandmadeEffectsPedal #Equalizer
