Spaceman Rumblefuzz II
Spaceman · pedal
The Spaceman Rumblefuzz II is a boutique fuzz built for bass and baritone guitar, delivering full, round low end with a distinctive bite that cuts through a mix, and a wide range from transparent, amp-like overdrive to a thick, sustain-laden wall of fuzz. The Rumble control tailors bass response from tight overdrive tones to incredibly fat, heavy fuzz, while the Bite control governs gain across an overdrive-to-distortion-to-fuzz range, and a three-position voicing toggle shifts bias, compression, and presence for distinct tonal characters. Version II adds 10dB of extra output volume, a third toggle position, and an expanded tonal range on the Rumble control over the original 2009 circuit. It responds dynamically and naturally to playing intensity and instrument controls, acting like a true extension of the instrument. It suits bass and baritone players wanting a genuinely versatile, characterful fuzz with real low-end authority.
