Hi there,

I have a Holier Grail pedal – after about 5 minutes or so of being plugged in, it starts buzzing and the signal is cut – however when I put the pedal in bypass mode, it seems to work fine (i.e. the clean signal is fine).

Would this more likely be a problem with the power supply, or the pedal itself? Once I unplug the power supply and then plug it in again, the pedal works fine, but then after a couple of minutes the problem reoccurs.

Many thanks for your help in advance.
