I just bought one for $650.
not much, they arent the classic fender people like
It really depends on the condition of the bass and which market you sell it in. I'd estimate over $10,000.
I paid $500 with original hard shell case on Ebay!
$300-$400
If you mean "Mint" and not just really nice, AND it is ALL original It's worth about $15000 to $18,000.
Whatever someone is willing to pay for it!
how much is a mexican fender telecaster custom guitar 2004/5 worth
The 1970s Fender guitars (including bass guitars) are highly desirable models, especially those in near mint, fully playable condition. At auction, a 1975 Jazz Bass in similar condition could bring $1200 to as much as $2000 or more, particular if it has a case and is as close to mint as possible. Expect a retailer to price a unit at the higher end of this range.
too much
Fender Jazz basses after the 1980's do not go for much higher than brand new Fender basses. I would estimate the price of your bass at around 1000, or if you are lucky 1500.
12 to 15 hundred, depending on how much the seller loves it!
This arrangement reduces hum - much like when both pickups on the jazz bass are turned on.
