I've now fitted my SX P bass with the Mighty Mite neck that I bought from Nick. I'm really pleased with the results. This is how I did it.
1. I took of the old neck and tried the MM one for size. Not a bad fit but with one crew in the existing 4 holes lined up perfectly however there was a 1/8' gap at the heel.
2. So I drilled out the neck screw holes with a 6mm bit and glued wooden dowels to fill the holes last week.
3. Today I sawed the dowels off and levelled the ends with a very sharp chisel.
4. I placed the neck in the body and making sure it was butted tight into the end of the socket marked the new screw holes with a 3mm bit and hand drill.
5. I drilled the screw holes with the neck, body and back plate in place, having marked the depth on the drill bit ( measurement taken from the old neck + body holes) with masking tape.
6. Rubbed a bit of candle wax on the screws and screwed the neck on checking all was lined up; It was !
7. Removed the Gotoh tuners from the old SX neck. Some of the screwheads had been buggered up by the person who fitted them originally so I had to cut slots with a mini hacksaw and use a flat blade screwdriver.
8. Fitted the lovely Gotoh '70s tuners. I had to re-drill the screw holes onto the MM neck. I'd have replaced the screws if I had spare but couldn't wait.
9. Restrung, adjusted the intonation, truss rod and action.
!0. All done. I now have an SX body Mighty Mite neck, Wizard Thumper, pickup, CTS pots and gotoh tuners P bass and it's lovely.
