The Carl Martin Crunch Drive is a 9V-battery-powered pedal designed to emulate that “hard to get” crunchy blues tone from a good tube amp. The Attack (mid) and Edge (treble) controls give access to a variety of flavors within this type of distortion style without compromising sonic quality. If subtle crunch is your thing, you’ll find plenty of cool chord and light solo options here which – regardless of EQ – always sound crisp and lively perfect for jangly chords and light blues soloing. The Carl Martin Crunch Drive is true bypass and features an AC adapter jack.
