Built with a layered JFET overdrive design, a high-gain, low-noise custom op amp, and easy three-knob control layout, the Keeley 1962 Overdrive summons the sound and power of a '60s tweed amplifier in a stompbox. Designed with a throaty dual gain stage implemented with their coveted Katana clean boost circuitry, this overdrive's components are hand-soldered for the most faithful vintage sound replications and consistency in use after use.
