Any type of fender jazzmaster guitar with upgrades or modifications that enhances the already superb sound of a stock jazzmaster.
This is commonly done by changing the soapbar pickups with Telecaster Deluxe humbuckers. Originally created by Sonic Youth guitarist Lee Ranaldo around 1996. It was a 1966-1975 vintage sunburst jazzmaster, which was stolen in 1999. A new jazzblaster then had to be made.
A: Oh dude, Lee Ronaldo's jazzmaster sounds unreal. I've never...

B: Whoa dude, wait, first of all that not a jazzmaster. It's a jazzblaster.

A: Oh sh*t!
