I'm thinking of drilling holes through the body of my Ibenez SGR 6. I saw someone who did this with a SGR 5 (b & e strings only) and he said it really helped out the sustain and tone. He kept the factory bridge and drilled the hole right through the metal. Does running strings through the body really help?? I'm seeing a lot of makers doing this, even Fender. I would think that once the string runs over the sadle the vibration is pretty dead, and running the string through won't do much more than the bridge itself..What do you folks think??
