I've recently started a descent into madness finding the perfect overdrive pedal and I've landed on a couple of TB favorites that have been infuriating interesting to work with. These two pedals, the One Control Blackberry and the SolidGold FX Beta DLX have controls that are quite a bit different from other pedals I have used in the past, where for example turning a knob a few degrees does not just add more or less of a parameter like gain or volume but introduce a whole new sound from the last one you had dialed in. Both these pedals can go from "Oh wow, this is IT!!" to elephant farts and amplified static without any apparent rhyme or reason from how the switches and knobs are labeled. I found myself having to take photos of the knob positions when I land on something good. What are some other pedals that can go from sublime to utter crap with just a simple tweak of the controls?
