I have a Peavey Cirrus 4 that I'm going to string BEAD. What gauge strings should I use? My luthier is going to dremel the nut to accomodate a larger string but the bridge will be the limiting factor on how big a string we can use. Does anyone tune BEAD and do you use light 5's or heavy 4's? The lightest 5 sets have a .120 B, and the heaviest 4 sets seems to be about .110 on the big string.
