Sully? Ken? Dave(budman), Ace, Any tech/luthier?
I need help with an intonation problem. I've been doing setups for years and I have never come across this one.
I just got a 99 Custom Shop Arch Top Dinky. It's 24-3/4 scale. This guitar is perfect in every way, it plays great, great action, nice slinky feel due to the shorter scale, the typical Jackson. After it came (yesterday) I decided to throw a set of strings on, but not go full bore for a complete setup yet. It seemed fine in every way so why go nuts? I don't know what was on it, but I threw a set of D'Addario 10-46's on it. Every thing was cool until I went to adjust the fine tuners on the OFR so that they were around the middle of their travel. I noticed that the E,A and G string saddles would were bottoming out against the back of the baseplate. The reason? they were adjust all the way back to the 3rd screw hole. No big deal. It's probably just that the intonation needs to be set. So I plug into my old faithful Peterson Strobe tuner. According to the tuner (and I double checked it with my Yamaha and POD tuners) The saddle needed to go back even further. Wierd! It was back as far as it could go. I measured first from the nut to the center of the 12th fret. Perfect at 12-3/8". The I measure from the center of the 12th to the Floyd. 12-3/8" falls short of the saddles by quite a bit. I know it's not going to be dead on, but I've always experienced it falling within the general area. I checked the posts and figured that maybe it's pushing Towards the neck. I've seen this before, but they were dead straight up. Check out the pic belowof the scale length from the 12th to the Floyd.
I can't believe that this guitar went through QC at Jackson like this. Besides, it doesn't make sense to me any way. Am I missing something?
Am I crazy? If the string is to pitch and the 12th fret fretted is sharp, you move the saddle back until it's to pitch. If it's flat, you move the saddle up until it's to pitch. Correct?
Other than this one thing, this guitar is perfect and drop dead gorgeous.
