Sorry, had to pop out to pick up the kids!
Playability wise it's fantastic. I cannot fault it and it has a great "acoustic" sound and resonance. It's pretty lightweight too.
Plugged in, I don't think I've really found its sweet spot yet. When I got it I had the pots and cap upgraded (maybe I have the wrong cap for the bass). I've had Nordstands in it and currently have Lindy Fralin PUs in it and I'm still working it out. TBH I have nothing really to compare it to. My other Jazz is the all ash/maple JB75 reissue - that has Nordstrands and a John East preamp and sounds like a totally different beast - a very modern "Super Jazz" type tone.
I may experiment with a different cap and/or different brand of strings with the JB66.
I'm looking at it now. It sure is pretty.....
