Made with an original design Chinese-made printed circuit board, referencing the Jan Ray circuit. It's a slightly unusual enclosure compared to regular effectors. It's equipped with a Vintage OPAMP 4558CP (Fairchild? See photo, please let me know if you recognize it! Maybe a premium item??). When I tested it, I liked the clear sound, without the typical muffled feel of the 4558, so I decided to keep it. An 8-pin socket is installed. Please swap it out if you don't like it. If there are any imperfections in the construction, please understand that it's a handmade item. //Specifications// Circuit: OPamp non-inverting amplification Di clipping circuit Function: Overdrive Pots: GAIN x 1, VOL x 1, TREBLE x 1, BASS x 1 Bypass: True bypass Size: 95 x 130 x 35 (excluding knobs, switches, etc.) Power: DC9V (center negative) Type...
