I'm looking for an excuse to begin pickup swapping, which will surely be a mess of buying and re-buying, after having the same pups for nearly 20 years...
I was playing a practice with the band, and when I hit an E chord the sound faded out like a slow volume pedal was being pressed. It came back, and a minute later it happened again. It was near the end of the night. Marshall JCM900, last tube change in the mid 90's. (It's been a hiatus for this amp).
I changed the batteries in my on-board preamp within the last 6 months - they usually last at least a year, but that could be a culprit. But the preamp is a mid boost, not a volume control.
Another wierd thing was a non-squealing feedback when I played the d and g strings, Sounded cool, but there was no controllong the note. I just started moving my fingers all over and laughing as it became clear I wasn't making the cool sound...
Do I need new tubes, or are my pickups shot?
