i've often considered moving on my '63 Burns Vista-Sonic bass, probably the only "rare" bass that i have that i wouldn't feel a pit in my stomach if i sold it.
'6? (haven't even checked the serial# !) Fender Mustang Fretless...looks to be a factory fretless (dot markers on the maple neck) with a r/wood or perhaps ebony f/board. plays like a POS, intonation is a word you'll find in a dictionary, not on this bass!
but - 'twas my first bass guitar ever, so will never be sold (well, unless i need a new hip or something!
)
'89 Rickenbacker 4008 Redneck. picked this up for a song many years ago, but she's been shelved after i found out how rare (and potentially valuable) it is. still, i don't think i'd ever sell it outright - like others, i'd rather use it in a trade for something that moves me a little more...4005, 4002, 1999RM, '68 CB 4001, maybe a CS...
who can do honest/accurate appraisals via photographs/video?
It's a good thing I don't play the stock market!!) Selling my 79 4001 is another matter entirely, though, and would probably take significant financial crisis to put it on the market.
