I am trying to increase the sustain of my guitars as much as I can, but I'm not sure I know as many setup tricks as I might need. The main guitar I am concerned about is a string through guitar with a tune 'o matic bridge. I don't know what kinda of frets it has...What is the difference between scalloped and "normal", or are there any other kinds? I'll try any trick you guys can think of to get some more sustain outta this guitar, thanks a bunch. ~DJ Snoo~
