Small update
The blend pot seems odd. Starting with the neck pickup on full and then gradually rolling the blend pot to half way between both pickups, ( there's an indent to know where halfway is ) there's no difference whatsoever in tone or volume. None
Its like the neck pickup is still on full. Its only when the blend is right back onto the bridge pickup, does all the vol and bottom end drop right off.
This is not how it was the day before, so i'm sort of leaning towards that as the problem. If it was that, i wouldn't know what to order, so its looking like guitar tech time
