An updated version of Guyatone's popular CB-3, the CBm5 Cool Booster offers a wide variety of useful boost functions in an extremely compact footprint.

The Level and Boost controls allow the user to adjust the degree of level boost and distortion to exacting degrees. You can boost solo passages, or distort an input signal while maintaining unity gain with the bypassed sound. The CBm5's dual mode switch alternates between clean and dirty boost sounds, the latter of which can be further tailored using the unit's Input Attenuator control. The CBm5's versatile Low-Boost/Hi-Boost Tone circuit allows the CBm5 to work equally well with Guitar or Bass.

Based on Guyatone's award-winning Micro Series effects, the Mighty Micros offer professional-grade features and exceptional sound quality in an ultra-compact, lightweight chassis that is 33% smaller and 50% lighter than your average stompbox.

The Guyatone Mighty Micros offer many improvements and additional features that Guyatone users have demanded, all packed into a rugged enclosure that retains the same-sized footprint as the original Micro Series effects.

Designed for the professional, working musician, Guyatone Mighty Micros feature superior-grade component selection for improved sound quality. Adjustable internal Input Attenuators allow use with a variety of instrument or input signals. All Guyatone Mighty Micros are covered by a 3-year parts and labor warranty through the manufacturer.
