Reviving an old thread. I just got an FT-135 in ex+ shape, except for high-ish action. Everything is solid and I want to keep it that way. Here's the plan.
1. Reinforce the neck block with the extra glue blocks.
2. Install threaded inserts in the neck; make a new, metal neck plate, install long ss machine screws through the neck plate/top/block/neck (Strat style), in effect making a solid sandwich so the string tension won't be trying to pull the block away from the back.
3. Use a 1 degree StewMac shim to change the angle of the neck to correct the high action.
4. Replace the entire adjustable saddle system with a Tusq saddle and rosewood spacers in the saddle slot. Not glued, just a friction fit.
I'm half-way though and should be done soon. I'll try and post pics.
