I tried a set of GHS A-270 mando strings. They use a 16 for the A string--all the other strings match the J74 set I've been using since day one. I just like that heavier A string, and the other strings seem to give pretty much the same kind of tone as the J74s. They cost alittle more than the J74s, but not if you're throwing out the 15 A and replacing it with a 16.
Anybody had any trouble with GHS strings? Anybody else use them?
