I play a Epiphone and frequently use the neck. But I never bend to much. Somtimes I bend the string behind the nut wich is the oposite to neck bend sound. Would be easyer to buy a guitar with a whammy but no way. Neck bend and behind nut bend work pretty fun but of course you can´t do Vai tricks ´cause it´s extremlly limited unless you bend too hard and than break the neck and get strings all over your face. Slash have at least protection, his huge hair.
