If he can figure which board, might be a really generic board.

I found GS cabs scooped in the upper mid, plenty of beefy midbass though, sounded massive when I was using a low A.

Probably need to solder that stuff, but you don't need to do whole seals just enough its all electrically connected, I usually do a smear of solder where three pieces meet.

Taking off the strings is the way. Something is wrong with the bass if this effects the action when you put them back as they were (or the strings are long past their best).
