I recently finished building the Pepperspray board. I like the overall sound, but.... Its a bit thin sounding. It also has a hiss or hum sound when you turn the pickups all the way down. If you turn them up you don't hear it. I swapped the transistors out with different ones (sockets), but the sound and the thinness persist. I have to turn my amp up to really hear the pedal too. Anyone had this?
