Sorry for the delay between replies, been away and busy with work unfortunately. Hopefully will get some time soon to progress with this.
Waz, Stan, thanks for the advice, I will PM Pablo and see what he says.
Stan, best I could do was a 20% discount off the body, which worked out at $9.95 US, or about $13 AUD. Actually that reminds me, I don't think they've paid it back yet.
Simon, yes thought of doing that as well, but not sure how it would look. Still haven't ordered the neck, will try to get that done this week. Probably best to wait and see when the neck arrives.
Wokka, here's a photo of my '98 US Jazz Deluxe, see the metal plate - most P-basses don't have this, but other Fenders do, J-bass being one, Jaguar another. Not sure why they do it for those models and not others, or what function it has other than being metal to ground the pot bodies to. It looks ok, so that's what I was figuring for this bitza/parts-caster bass. But as I said, haven't done much metal work so dunno if I could get it looking as good as this.
Will update when I hear some more. Thanks for all the advice.
