That shit said, it really comes down to feel.. Although they can be just as good, USA guitars don't feel anything like CS guitars.. At least, not to me. Their necks are bigger while being shaped differently as well. They have different top carves, different hardware, different frets, different everything.
Lastly, they sound about a million times better out of the box than anything USA makes... That's not to say you can't make a USA sound great, but again, it's easier with the CS. They tend to have a more organic, open tone whereas USAs are usually a bit brighter and focused.
Would it be worth it to lose two USAs for one Historic? That all depends on those USAs and which Historic.

Tell me about the two you have.
