Am using a newly bought 2017 Standard T in an orchestral setting and need it to be in tune, really in tune all the time. I noticed the b string going sharp toward the end of each act, also the g string sharp in general. I asked that it be set up for 10s when I bought it. That was problem #1, they put 10s on it but didn't file the nut accordingly. Since the nut is milled for 09, 11, and 16, the 10 gauge ddario strings didn't fit the slots, so hence the the sharpness as time passed, so brought it to a tech who filed the correct gauges on the nut. Regarding the g string, I noticed while intonating that the g string was sharp so dialed the back but ran out of room and it still was sharp, so turned the saddle around, faced the flat side toward the back which gave me a little more room for adjustment. Finally, I always use lubricant in the nut and saddlle but it's most important on LP, because of the angle that the g and d strings come off the nut, plus the angle of the headstock. Result; instrument is in tune across the board.
