Description
Fully functioning & in very good condition with some mild play wear.
Keeley Effects use the Texas Instruments RC4558P chip, just like early Ibanez TS808 Tube Screamers. Additional mods include replacing the carbon-composite output resistors with metal-film types that don't introduce noise to the signal and increasing the bass response for full low-end richness, and increasing the overdrive range. The result is a cleaner sound when turned down, twice the gain and drive when cranked, and stock TS808 sounds in between. The bypass circuitry was also improved, as well as the tone control circuit.
