I certainly wouldnt be tempted to buy any signature guitar for the fact that they are "signature", but if the guitar is all nice, then i could oversee that its a signature, so signature is really just a "minus" (even bigger turnoff if i dislike the guitarist). Buying something just because your favourite artist uses seems silly to me, but on the other hand, i do think i could consider some kind of Tony Iommi Signature, but big part because i love SGs, his SGs are pretty awesome looking, so, why not?
But then again, i have a nice Gothic Warpig SG made by Feline on its way which fills that spot :grr: :guitar4: But it kinda depends on the features on it, if it has something really cool or unique i could be interested, like the Fender Yngwie Malmsteen signature that has a scalloped board all over, that would be fun to give a try, but wouldnt buy it just like that, i guess i might aswell get some other scalloped, but you get the point!
Usually sigs are way more expensive aswell, just because they are related to a famous artist :non:
