I did a few fairly cheap add ons to my Bernie, which make it much better to live with and use.
It was a UK limited run of 50 which has the usa 53/10 pickups, but I swapped out the nut to a black USA widefat, and the tuners to Gotoh locking tuners.
(The nut it came with was binding on the high E string and I prefer locking tuners)
Then I recently added the amber lampshade knobs, which are much more tactile and look better too.
Nut, tuners and knobs were all a simple drop-in, and I think all in it cost me ~120quid to do the mods.
This guitar is staying in the home for life, love it.
