Thanks Gavin. I followed the guides and the wiring diagram. The action at the nut is very high, especially when compared to my strat, tele and les paul (not kits). The action appears standard down the length of the neck. Have just replaced strings with a higher gauge (10-46) and seems better, but will obviously need to adjust the nut height.
Would you recommend replacing the nut or deepening the string slots? Many thanks for your help
