Dunable Baphomets. I had a local luthier do the custom routing and wiring. I wanted pickups that were fairly hot and just something different as I'm not really too much into P pickups personally. Dunable do make Jazz and P pickups though and from their demos they do sound really nice.
Yep, was refinished by MJT. They are very, very good. Their turnaround is pretty quick and they are in contact with you through the whole process and will do anything as far as color and detail. Mine was their light relic in a dark Charcoal Frost Metallic. Highly recommend them if its in your budget - they do charge extra for poly stripping though which does add a bit. But they did exactly what I wanted. And as far as worth it, yes, to me - I like my guitars beat up as I'm already pretty rough with them to begin with. But I did opt to get a darker version of their stock color and only a light relic as I'm bound to add a lot more just through regular wear and how I play (and sweat lol). But the nitro finish is very durable and professionally done. It's definitely putting a lot of money into something that's just a finish but if you really like your bass' body and its a keeper, then its worth it.
Interesting about the neck, seems like you scored a really nice one! And that red body does look really nice with the aluminum!
