Very cool - always love the tele-style headstock and it looks good w/the jag-esk body. I'm going to want to hear your opinion of the JAX's as I'm also using them on my recent build Custom Performer/Supersonic bass
What colour are you doing? Will the headstock face match? Also, if the extra neck pu route won't be used, then are we talkin' pick-guard? Looking forward to seeing it develop!
