Not sure how to proceed really.
I decided this afternoon prior to doing anything else, to give it a decent set up.
After a bit of tweeking it's actually very playable. I'm pleasantly surprised by the neck and fret work. I was expecting some dodgy fret work with sharp ends etc. but it all seems quite sound and no sharp bits.
Plugged in its a bit lame, but I intend to change the pups and drop in one of Kiojons wiring kits.
Anyway I will start a build thread, I know it's a bit old hat and the P bass thing has been done over and over, but I like to keep a record. Also if I detail the whole thing, mistakes and all it might at least prove useful to someone else, embarking on a similair project.
Thanks for the advice so far, see you in the build thread.
