My SLSMG is my main guitar. I've done alot of work on it (almost nothing is stock) and it plays beautifully with lighter strings (50-11 in D standard and lighter gauges for higher tunings). The problem is is that now I tune to C# standard and with heavier strings (This set DR Strings Electric Guitar Nickel Plated Round Core with Stringlife, .010 - .056, SAL-10) it gets all sorts of buzz on the first few frets in addition to not being able to keep tune that well.
The only things I'm not comfortable doing myself (tech wise) is fretwork and filing a new nut. I had a tech do a setup with the 50-11 about a half year ago and he gave a clean bill of health for the frets, said they were in great condition and all was level. So I'm presuming the problem is that I need a new nut cut for this gauge of strings. The problem now is that there are no techs in the jackson area (The tech i took it too was in bozeman when I was attending college there) and I don't want to ship it off because a)its my only guitar at the moment b)I don't want to pay that much to ship two ways and risk getting my guitar damaged in shipping.
I don't know alot about nuts but everyone says its best to have the actual guitar in their hands to install the nut and adjust from there. I don't really have the option of having a tech do that since I don't want to ship my guitar off. So I figured since that I would contact a shop online and get them to make me a custom nut for those gauges of strings and ship it to me, since I'm comfortable aligning the nut and gluing it in myself. It seems like there ate alot of shops that have slsmgs/jacksons in stock so maybe they could just take the measurements form one they have in stock and make me a custom nut. Would the end result of this be close to if they had the actual guitar in their hands at the time of nut making?
-What would be a good,reputable shop to do this? I'm willing to pay for high quality
-What material is the best for nuts on guitars like the SLSMG?
Before changing the nut, you might want to increase your relief until the buzz goes away, then try the playability - I'd be surprised if you really need a new nut. The seems more like a relief issue, since the lower-tunes strings need more room to vibrate.
