Fret Level and Wiring on Yamaha SA2100

Great semi acoustic in for a fret level. I doubt there’s another level in these frets but they came out nice and the guitar plays really well. The treble tone pot, which is push/push to activate the coil tap was noisy and couldn’t be repaired so I replaced it.

The bridge has collapsed and it might be an idea to replace it. If you look you can see it sinks in the middle, plus it sits at quite an odd angle. It is perfectly serviceable but I’m anal about these things
