i've got the stormy neck (a2) in a les paul (tokai) and it is indeed gorgeous tonally if your into cleans aka goerge benson, larry carlton etc.it would be different in a semi but i don't see how it could sound bad.
on another note i thought the stock pups on the tokai where poor, especially for cleans but i bought it knowing
i could bk it and still be miles under the price of a gibbo despite the tokai being a higher end model.they're 11k (mk2paf) and possibly the same on the one your after.
i'd be a little worried changing the pups in an es however, it looks like a ball ache, in fact does anyone know how to go about it.( i too have 335 gas after andy's ngd, but it'll be jap.)
