I own one of these volume pedals and have noticed that with my active pickups when I play with the pedal half way up there is far less gain. Anyone know why this is or can explain this?
so i noticed... now how can I get it, or something to keep it from losing the gain but lower the volume for a swell that doesnt change the gain
put the pedal in the effects loop of your amp or if you are using a distortion pedal, put the volume pedal after the distortion pedal in your chain.

if you are using amp distortion and there is no effects loop then you are fresh out of luck.
