These Stratocasters from the 70’s had very thin fretboards that are just veneers laid over the neck, meaning they are very thin which can cause problems when doing refrets as you need to level the board before you put the new frets in.
This guitar had a twist which meant it needed a little more levelling than usual and luckily there was just enough wood to get it level. The finished guitar had all the metal work cleaned wiring checked and a full setup.
