Finding to this point from sitting for so long.
When I run it through the Line6, it appears the contacts in the PUP switch have gotten gumbed up or corroded. One minute they will be loud, crisp and clear then when switched it might get a bad connection and be distorted, low volume, or good. Never know until ya hit the strings. Dont think there is a good fix outside of replacing the switch.
Definitely will be cleaning the fret board up and treating it.
Love the tones and clean PUPS when the switch isnt acting up.
