Hello. Iíve made this project today, works great, but iíve got a little humming issue while playing.

It happens when i touch the guitar strings (and playing of course :D), and goes away as soon as i release the strings. Iíve got active Pupís on my guitar and dont have any grounding problem with it, what should i do?

Also, if i close the volume knob all the way down, i can still hear a little sound from the pedal. I've used a B500 Potentiometer, is that the reason?
