When Fender announced they were making a MIM Cobain Jaguar I was pretty excited about it. My only issue is/was I don't really like Jaguars or Mustangs. I want to like them, but so far I just don't. I like Telecasters and Jazzmasters best. (And contoured Jag-Stangs which seem to be the only short scales I bond with.)
I have had this Sunburst Blacktop Jazzmaster for awhile.

I did enjoy it stock but I ended up trying to sell it. I didn't get any takers so I decided to modify it. I have two Jazzmasters with standard pickups and such and I have one I am building with WRHB's I have. I was going to put those in the guitar, but ended up getting a Black Blacktop Jazzmaster I am going with. Since I had routed it for WRHB I thought I should put humbuckers in it and make a Jazzblaster for a different Jazzmaster option. I thought on what pickups to use and though "I want to try a Super Distortion." Then it hit me, why not try to make a Jazzmaster look like a Jaguar?" Then I though, "I could try to make it look like Kurt's Jaguar!" I don't dig Jaguar switches, so a toggle would be better. I don't use rollers much in my Jazzy's so I figured I could just screw it down to the wood with black tape under it to give the appearence of something under it. I checked bodies, and it looks doable. Tony at Pickguardian.com does great pickguard work, so I am excited to see how it looks when the guard he is making me comes in.

The funny thing is the Blacktop Jazzmaster logo looks very similar to the strange decal that was on Kurt's Jaguar.
