Detail 01
Jazz/Rock voicing switch
Jazz provides a smoother attack with reduced output; Rock increases gain and punch for a more aggressive response.

Independent shopping perspective
Bigger Bloom is an analog, preamp-style overdrive for moving an amp from articulate low gain into sustained lead drive. Its revised gain structure adds midrange presence and retains note definition at higher settings, while Drive, Accent, Tone, and Volume provide hands-on control of gain, presence, EQ response, and output. Switch between the softer, lower-output Jazz voice and the hotter Rock setting when the part needs more gain and punch. Top-mounted jacks help conserve pedalboard space.
