A video that will answer the age old Tune-O-Matic questions: Which way should the intonation screws face? What direction do the saddles go? Wrap around tailpiece, good or bad? For reference; the nickel Tune-O-Matic is a Nashville, the rest are ABR-1 style bridges. I hope this is useful!
Cliffs Notes:
On the Gibson ABR-1 The intonation screws face the neck.
The Nashville Bridge the intonation screws face the rear, strap button end of the guitar.
The saddles are ‘generally’ with the low E and A strings; the flats face the rear, butt end of the guitar. The other 4 saddles, the flats are oriented towards the pickups/ neck of the guitar. In my experience Gibson used to orient the saddles w/ the 3 wound strings, the flats face the rear, the three treble strings, the flats face the pickups/ neck.
