Last night I had a guy bring in a tube pre pedal my meters sky rocketed even With a pad engaged and the pedal volume very low, the gain all the way down on my pre it was still overloading my Tone Beasts DI. We switched the pedal out and the problem persisted. This morning my Pre wont even turn on. Im not very happy about this. What can I do? Im a Newbie. Ive made a HB1176 and a few OpAmps. Anyone know what may be a fix to my problem? Willing to send her off for repair if it needs to be!
