I bought a brand new Holy Grail Plus reverb pedal about a month and a half ago. Only a few weeks later, though, it stopped powering on consistently and sometimes when I do get it to turn on, there’s no reverb. Is there anything I can do? It’s a great sounding pedal, but it’s been a constant source of frustration, especially since I got it partially to avoid the problems that the original grail is known to have.
