i've had this pedal for ages now, and it has served me well until about a day ago.

the volume knob on the pedal shook a little bit loose, which originally i didn't think was going to be much of a problem, and as i was playing a bit tonight, i would adjust the volume of the pedal, and the ****er would just totally cut off sound for a few seconds. It's the last pedal in my chain, so that's a big problem.

espescially because i have a gig friday, and i play music heavily based on that pedal, and i really can't shell out another 100+ for a decent delay/hold mode

can anyone help me out?
