well I'm only putting 2 bass strings on, and they're tuned very low, so I'm not really worried about the neck warping. and I've still got 3 guitar strings on there, so their's still proper tension on the tremolo and neck.

I'm doing this because I need a really guttural, distorted bass rhythm (in place of a rhythm guitar), but I still need the high end for bridges/solos. so I'm stringing my guitar with bass AND guitar strings so I don't have to add a third bass player.

really I'm doing more modifications to the strings than to the guitar. I might have to just break down and have it professionally done. I'm just worried about the cost :(
