Here is the 1978 Fender Musicmaster bass body including strap pins and bridge assembly:
Here is the 1978 Fender Musicmaster pickguard with original pickup, volume and tone pots, wiring, knobs and output jack (1978 serial number, 1977 date on the tone pot): SOLD
Body shows to have its original finish, and has the sort of wear you might expect from an original vintage 35 year old body. There are dings, scratches, and swirls all over. The pickguard also shows swirls, string wear, and scratches that one would expect on a 35 year old piece. The photos look just a little bit nicer than the pieces do in person but are fairly respresentative.
$175. for the body, $75. for the loaded pickguard, $235. for all. Prices include shipping in the conUS. Trade offers considered but cash is much preferred.
