Inside this pocket-size device is everything necessary for treating your tone to that classic Manhattan-style compression, with a simple 2-knob layout to dial in your ideal settings. By blending your dry signal with the compressed signal, the Compressor Mini enhances clarity and note definition while beefing up your sound. An increased sustain range and Keeley's new-and-improved transient release time only sweeten the pot — it's guaranteed to make humbucker and single-coil pickups sound their absolute best.
