I face this problem too. I play mostly soul & jazz (Plate option being a reason for buying this pedal) and I find it disappointing having to keep it always at minimum. Surely takes away the fun of searching for the sweet spot as the only option for me is moving the pot just a notch. I get it that some people like the ambient stuff but when I read Spring and Plate reverb I tend to expect the classic situations that these reverbs where used in the guitar world as many other people do. The fact is that the pedal gets to ambient territory very early, occupying a lot of knob range which could be reserved for the more subtle settings, which I believe is where the most accuracy is needed rather than the drenched settings.

So to answer the OP’s question, would replacing the potentiometer with one of different resistance (or even tapering) do any difference? If not, is there a way to reprogram it through the multipin?
