josh super mags can be braced at like 7 1/4" to about 8 1/4".Yeah I know thats a big spread 1" but I always try and start at 7 1/2 and then work up or down 1/4" on the sm's.They well generaly quiet down a little and not have so much hand shock in that range.I'll screw up here I bet but I was thinking the string was 44 1/2 for some odd reason.After you make one let me know the braced length of the string would you ?bd
