Is this a fair trade? Warwick FNA Jazzman for Warwick Thumb

[Tomis17]

A guy is offering his Thumb bass for my FNA Jazzman. Is that a fair trade? I am a rocker and the Jazzman just doesn't do it for me. The guy making the offer is a funk player and the Thumb just doesn't do it for him. What I'm wondering is are the values of the basses about the same? Am I going to get completely ripped off if I go ahead with the trade?

I answered under the other tread.
It's pretty much an even swap, if the Thumb is a BO. If It's Neck Thru, it's a steal.
