1) Welcome to the forum family!!
2) Get in touch with customer service - they're the best in the business and issues like his are exactly what they are there for. Let them help you.
3) Wood moves with temperature and humidity changes. Thinner necks are more pone to this than thick necks. It's totally normal, it's one reason why we have adjustable truss rods and why Music Man have made their so easy to adjust.
4) Factory spec is John Petrucci's set up. That may not suit everyone's playing style and picking technique and some of us need more action or neck relief to bring fret buzz to an acceptable level.
5) unofficial forum rule - your guitar doesn't exist without pictures!![]()
Hello and welcome
If the frets were sharp when you bought your guitar, that means that the hydrometry of the shop was not so good (too dry). Now in your house the neck will adapt itself to its new environment. It can take time. Perhaps it's a good idea to wait a bit before sending it to CS.
Well I've had my JPX for 3 months now and I have to adjust the truss rod almost every time I play it.
My music room is in my basement and so the temperature gets pretty cool, when I get in there and heat it up then the temp gets adjusted again. But when I start playing and have to adjust the truss rod, it's before it warms up, so it must be the cooler temp that's doing it. I wonder if I should monitor it to see HOW cool it gets.
But yea, I adjust mine all the time, and I've seen several posts here where people are, and it seems it's the JPX more than the other JPs. I absolutely love the guitar though.
My JPX seems a little more sensitive too. Not as much as either of you describe.. but more so than my other guitars. It's strange.... But I love the guitar.. it's fantastic! For reference, I've had mine for a year and 3 months. Mine had an issues I did have to send it back to EBMM for. The nut was wearing away and was too deeply cut on the 3 bass-side strings. I attribute that to the fact that my JPX was a guitar center rescue. Most guitar I've rescued from there have some strange problems that come from all the hands touching them and abusing them.. and sometimes guitar center neglect.......![]()
KEEP IT IN YOUR CASE!!!!! Sorry for the caps but its an important message. I have had my JPXI7 for 6 months and use to adjust the truss every 2 weeks. I experimented a month ago and everytime Im done playing it I put it back in the case. I have not had to adjust my neck once. Hell, I havnt tuned a single string in a month (I dont use the bar). I play it every day. Some times a few hours, some times a few min....I also use a 32/64 ruler to measure and it literally has not moved.
Try it out, take detailed measurements and then case it when your done..........
I have not adjusted my truss rod in over a year. Is this bad?
I don't think it's bad at all. If your action stays the way you set it, then no need to. I too have ones that there is no need to adjust.
They are! But what can they do? Replace the neck? I think it's inherent in the design.Get in touch with customer service - they're the best in the business and issues like his are exactly what they are there for.
I don't think so, if anything it should add stability (i.e. denser wood?)I wonder of the ebony fretboard has anything to do with it.
Huh, well that's interesting. So the case either provides the temperature stability (were you exposing the guitar to any sort of temperature swings?), or structural stability (what I'd guess). Unfortunately this just won't work for me, my guitars are out -- I play them regularly. Plus, none of my other guitars do this, even my other two EBMMs (Axis & SM-Y2D).I experimented a month ago and everytime Im done playing it I put it back in the case. I have not had to adjust my neck once.
Well that's promising! Perhaps I'll revisit this topic in a year from now. There's hope!My JPX required constant tweaks the first few months I owned it. However I don't think I have had to touch the truss once in the past year or more.
So I haven't heard anyone mention string gauge? Can anyone interested in this topic post their string gauges?
I use Ernie Ball Hybrid Slinky 9's (9's on the top, 10's on the bottom)
(ahem, of course, but they really ARE the best string on the market IMHO).
