I use an Ernie Ball Jr. 25k version for my Sadowsky bass (active) and find that most of the volume adjustment happens in the last 10% of the pedal sweep. I would like to actually use the pedal for volume swells and for decrescendos (fade-outs) in orchestral music. Does anyone have experience with these pedals for that use? Is there a modification to improve the sweep rate? I'd rather not buy another one ($$) if the Jr. can be changed. I'll get a cramp in my foot if I have to use it as is. Thanks.
