I'm looking for a distortion pedal to be used with various instruments that produce frequencies anywhere in the spectrum of 20 hz - 12,000+ hz.
I have guitar fuzz pedals that produce strong high end and high-mid distortions, but are lacking outside of that. What are some distortion pedals that produce a very audible effect on the low and low-mid frequency ranges (e.g. below 5000 hz)? True bypass in the switch is also desirable, but not required.
