ship all of their used gear overseas including to South Africa ?
Ive looked through the catalogue and they have some really great stock which changes from day to day.
You can pick up great bargains from there like Custom Shop Fenders for R14000 as well as Gibson Custom shops as well ?
Its listed per condition and they state exactly what is wrong with the instrument(scratches, dents etc)
Shipping for a guitar is around about $210 and since its used there should be minimal or no import tax.
I shipped a Bogner Uberschall and I paid exactly zero Rands import duties ?
Go have a look ???
