Do I need to take any precautions or special revisions with a rosewood fretboard?
Just clean/condition it with lemon oil once or twice a year.
Oh and how much should I expect to pay for a set of D'addario EXL120?
I'm embarrassed to say I don't know :-[. I buy by the box and get a good price for the whole box - I pay attention to the discount, rather than the end price. I'd guess about R70 a set is the going price - obviously more if you're paying someone to fit them too. Anyone?
