Second hand. Excellent condition. The RC Booster offers a super transparent 20db+ clean boost with an adjustable ±15dB two band active EQ that adds a wide range of harmonic content to your ideal sound. As a clean boost, it can enhance other pedals, such as "overdrive and distortion pedals," or you can crank the gain for a "crunch" sound. But, the RC Booster is so extremley transparent that many players find they leave it on all the time. It also features true bypass for eliminating any signal interference when switched off.
