I want to sell this guitar to a good friend. It has been my number #1 for many years, but I play other guitars right now. My friend really love this guitar. It's a '76 Telecaster, natural with original case. Non-original parts include pickguard, one pot (original in the case), pro refret, and the pickups are Fralins but the originals are in the case in great working condition. What would be a fair price for both of us?
