Keeley · pedal
The Keeley KTM-B Time Machine Boost is a clean boost pedal from Keeley Electronics designed to provide transparent, high-quality signal level increase without coloring the guitar's natural tone or the amp's character. The JFET-based circuit delivers clean, transparent boost with minimal noise and signal degradation, suited to pushing tube amplifiers into natural breakup or raising solo levels without changing the underlying tone. One of Keeley's foundational utility pedal designs.
