Hello world. New here, hope this thread lands in the right place. So I have been messing around for awhile now with different string gauges for my baritone in GGCFAD tuning. I have an ESP LTD MHB-400, 27" scale length. My problem is the low G string. I have tried different gauges, from 56 all the way up to 68 and just recently fitted it with Ernie Ball 13-72 baritone slinky's. The remaining five strings are a-okay, I'd even say a bit too tight now, with the 72 set, but no matter the gauge, that low G always goes sharp, when tuned to pitch. So when I pick, it goes about 20 to 30 cents sharp and then slowly comes back to pitch into G. I have seen a little bit of improvement with the 72, doesn't go AS sharp anymore, but it's still there. For the time being, I'm tuning the sixth string a little bit lower, based on the strength of my right hand attack, so it actually goes sharp INTO G from like -20 cents, right between F# and G. This only works for faster licks n riffs however, where the string doesn't ring out for longer than a second or so. Playing anything else, where the G rings out for a longer period of time, the string gradually sways back down to somewhere between F# and G. I HAVE also adjusted the neck profile, bridge/action and intonationf or each set of strings I've experimented with, so everything has always been set up correctly for the different gauges. Any helpful information on what else to consider, any modifications I can do, etc. would be greatly appreciated! In love with this tuning, especially on a baritone, so hoping to get this to stay MORE in tune. I do also realize, that there's just an inherent point, where getting a perfectly in tune instrument at such low pitches isn't feasible anymore, but I'm sure there are things I could try. Thanks in advance and looking forward to your thoughts on this!
