Home › Forums › Help/Technical Questions › Holy grail nano problem
My holy grail nano only passes dry signal (no effect). The reverb level knob lowers the dry signal so that full-right makes the pedal silent. Any chance I can find and replace the component that has failed?
Probably the output op-amp. I’ve seen that same problem on the big box units.
Thanks EH Man. Don’t suppose you have the part ID for the op amp at issue? I see a few It looks microscopic & surface mounted so I think it’ll test my soldering skills but I suppose I couldn’t make it worse than it is now. Thanks!
If it’s like the older units it would be LMV358.
