The Mustang is one of the most affordable (if not the most affordable) vintage Fender electrics you can buy. You'll see from that link that the price is surprisingly low for a Fender that old. It's not because the guitar has anything wrong with it other than a few minor cosmetic issues. Mustangs just don't command high prices.
Incredible Axe! Looks and sounds beautiful! It's been in my family for a long time, my father purchased it brand new in California back in 71! The heavy, solid body provides a warm thick sound that cannot be replicated. All parts are 100% original and genuine Fender! Body is great shape given the age and mileage, some small knicks (all pictured).
