Hello, I need your opinion on the following mods im going to be doing on my MIM J-Bass. I also have a couple of questions. 1. Basslines SJB-2 - Hot Bass Pickups Will they fit in the pickup holes or will i have to go get them customized? 2. Chrome Ashtrays I already ordered them. 3. Black Pickguard Link - Fender® Accs. Jazz Bass Pickguard 3-Ply Will this fit my MIM JBASS. If not, where can I get one for a MIM, Any suggestions? Thank for your help!
