Cheers for the suggestions guys. I played a Gibbo SG at lunchtime today, and didn't really get on with it. Nothing i can really put my finger on, but I just didn't vibe with it. I also have a feeling i'd end up replacing the pickups with Nailbombs or something simliar.
As far as the custom idea goes, it's something I'm definitely open to in the future, but when I 've got enough money to really do it properly - if I did it on this budget I'd end up skimping on something and it'd annoy me! However, the pic of that Wez V guitar above made me think of the Fernandes Ravelle, so after a look on their website, that's on the list to look at.
