I originally purchased it at the Fullerton factory in 1978. I've used the heck out of it. Yes, those are real wear marks, unlike the phony road worn stuff they've been putting out at Fender lately. Gibson also does a worn thing also. I was around 20 when I got my Mustang and now I'm 54. I wonder how old Kurt Cobain was back in 1978? I have ten guitars now. Stuff like 2 Strats, 2 Teles, one Gibson Les Paul Special SL 1998 I purchased new and it's still pretty mint as I type this. I have other guitars as well and mostly small tube amps, ranging in watts from 5 to 15. One solid state Sunn alpha 112r they don't make Sunn no more! I play my instruments but I baby them alot more these days! My Washburn D10N acoustic with the bone saddle I installed myself is probably the guitar I abuse the most these days, and I still try to baby it. When I was younger I was careless, these days I look before leaping! If you have any other questions. please feel free to ask.
