Hiya - you may recall my horror after knocking over my bass and snapping one of the tuners in half.
I tried to get a single one and bought one from USA - wrong size - I subsequently had to buy a set of 4 used ones, again from the USA. Thankfully - one now fits.
My bass is restored to its former glory but I now have one brand new, unfitted smaller one and 3 larger, used but perfect nick larger ones going spare.
£32 each inc UK postage. Less than I paid.
