hey i have a jackson dk2m with ivoroid binding that travels up the entire neck im pretty sure that my fretboard has dried out severly because there is a gap from about the 7th fret to the 15th fret only on the bottom side of the neck its a decent little gap like a thin guitar pick can almost fit into it im curious to what i can do to rememdy this OTHER then taking off all the frets and taking off the binding and putting in new binding and refretting the guitar (that would cost almost as much as the guitar most likely) i just want to know if theres anything else guitar techs or luthiers do when theres a gap between the fretboard and binding do they fill it with a type of wooddust and glue? do they leave it and just bring the guitar back to life with a humidifier or is the only thing to be done is to take off the frets remove the binding and install a new binding..PLEASE HELP any information is appreciated
All you can do is try to bring the humidity up in the area the guitar is stored and hope for the best. Do not try to increase humidity by oiling the fretboard either.
Moving on.....
as mentioned above, try to humidify the guitar a little bit. do it very gently though, like having a humidifier on low in the same room the guitar is stored in type of deal. its pretty normal to get some fret-board shrinkage in during drier months (usually winter, if you live somewhere with real winter). my G&L has its fret ends stick out a little bit during really cold periods (probably not too dissimilar an amount of shrinkage).

you can't really fix the problem so much as you can minimize the cause though. don't apply anything to the guitar, and do not try and humidify it quickly. nothings broken, just humidify the guitar gently
