A few years back I bought an ESP LTD-FM 418 with a 25.5 inch scale. The gauges are .10, .13, .17, .30, .42, .52, .64, .74. It sounds great in standard F# with lots of tension which I like but I prefer to tune a half step down to F. This being the 1st 8 string guitar I've owned I did not realize 25.5" flat out wasn't enough to accommodate the tension. I am looking into an Agile Septor 827 with a 27" scale and mahogany body for a tighter sound and more sustain. I would possibly consider a 28.625" scale but no more than that. I'm looking to have the same tension as I have in F# on my 25.5", in F on a 27" without any buzzing. I really like the 10-74 set I have now but I'm more than sure Ill have to find a new set with a new scale in a lower tuning. Any help with this and any suggestions regarding another scale length and gauges would be AWESOME!
