The ProCo RAT 2 is a classic hard-clipping distortion pedal whose circuit dates to the late 1970s, built around an LM308 op-amp and silicon diode clipping. Its three controls are Distortion, Filter, and Volume, with the distinctive Filter knob acting as a reversed tone control that runs from bright and cutting to dark and warm. Capable of far more than its name suggests, it spans gritty low-gain overdrive, thick midrange distortion, and nearly fuzz-like saturation while keeping notes present and clear even at high gain. It is a staple of punk, grunge, garage, stoner, doom, and alternative rock, and has been used by players from Jeff Beck and Thom Yorke to countless heavy and experimental guitarists. Dynamic and harmonically rich, it cleans up with guitar volume and stays articulate rather than overly compressed.
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.
