The Rumblefish is a warm transistor fuzz that is excellent for bass guitar. The present top end ensures you won't get buried in the mix, and the Rumble knob dials in the amount of low end, which shapes the character of the fuzz. The Bite knob adds in harmonics and brightness, and the Diode switch toggles silicone and germanium diodes for a different clipping texture. Not only is it a unique fuzz tone, but it also works great as a light overdrive and tone shaper.



Fuzz - Output volume level

Bite - Gain/saturation of the fuzz

Rumble - Low end response

Diode - Switches between germanium and silicone diodes


The pedal requires a 9V DC power supply (not included). The DC supply should be a standard Boss style connector, center negative polarity. The current draw is approximately 10 mA.


The Rumblefish has a true bypass switch.


Dimensions: 4.77" long x 2.6" wide
