I have a couple more questions about guitar bodies. One is what advantage is there to a one piece solid body electric guitar? Is there any tone difference? Also since the company I am ordering from (warmoth) does not have H-S-H setup in stock like I want I have to rear route (or so they tell me). I dont mind the slight difference in price (though can someone explain rear routing to me as well?) but I would like to have a tremolo bar for my guitar but I cannot find this option for rear routing. Is a tremolo bar with rear routing impossible or am I jut blind?

Thanks,
Jimmy
