ok, time to start my epicly long rant.
i have an rg2550z with an edge zero bridge. it has a problem. some of the frets (usually 1 on the B and 1 on the G string) have about 25% of the sustain of a normal fret and sometimes are just octave harmonics (eg. 15th fret B string sounds like 24th fret high E).
so i bought one of these guitars and was amazed with how good it was for a few months. then, when i was re-adjusting the intonation, i noticed a fret on the high E had the problem i described before. i kind of shrugged it off because it disappeared as i set my intonation. i also noticed occasionally the bridge would make funny noises and vibrations for no reason and would go back to normal if i fiddled with the fine tuner a bit.
so, a few weeks went on and the guitar was playing great. then all hell broke loose.
my 14th fret on the B string got this problem, like, really badly. the note basically didn't exist. and i tried to fix it, GOOD LORD i did every possible thing i could think of. basically, i knew moving the saddle back and forth (eg. setting intonation) moved the problem back and forth in accordance to the saddle. but that obviously isn't a good fix.
fiddling with the nut
fiddling with the headstock tuners
EVERY possible neck bow adjustment you can think of
whammy bar arm holder/edge zero intonation tool fiddled with
put tape on springs
swapped saddles around
checked saddles for burrs at contact point
tested problem with every part removed possible from bridge
different string gauges
ugh, basically EVERYTHING possible. so i took it to a luthier and this guy said it was the frequency of the wood of the guitar and so i was able to get another rg2550z. by this time, i had 2 frets with the problem.
to my utter and COMPLETE dismay, the new guitar has the EXACT. SAME. PROBLEM! and to my HORROR in the SAME GODDAMN AREA! the old guitar had the problem in the 13-14th fret on the B string and on the 14th-15th fret on the G string.
i take this new guitar home, set it up and to my sheer disbelief, i get owned again. so by now, i kinda suspected it was the bridge of the guitar and had resigned myself to the fact that i just had to live with it.
a week ago, i took it, as a last resort plan, to a different tech (the guys i first went to had no idea what i was talking about and couldn't even hear the problem). this guy i went to said he thought he could fix it, and free of charge too. so i gave the guitar to him for a week and yesterday i went in and he said he had improved it drastically and he had. i was astonished.
he shimmed the neck (i'm 90% sure, i haven't taken the neck off), added a washer to the intonation adjustment tool, gave it a complete fret dress and basically a really pro set up. i took it home, and every fret was sounding at 90-100% as it should and i was amazed.
however, i restrung the damn thing just then and the problem is BACK! i'm seriously, SERIOUSLY annoyed.
now, to the serious issues...i hope you've read this far...
i'm about 95% sure the problem has something to do with the bridge. my main reasoning is that; A) EVERY single thing you can imagine has been tested/adjusted except the whole bridge B) the bridge vibrates and resonates in a strange jarring way when you play the affected frets and ONLY the affected frets.
so what i was thinking is, i buy an edge pro and retrofit it onto this guitar. i've done some basic measurements and the only problem at this stage is (i think...) finding a way to screw the edge pro spring claw screws in. i did some measurements on an original edge equipped RG and found that, because of the spring tension adjustment knob on the EZ system, i need about 8mm or so extra wood to screw the spring claw for an EP in.
i know this is possible thanks to none other than mr. herman li. check out this vid and pause it around 2:27:
you can clearly see how a block of wood has been fitted in where the adjustment knob was and the EP claw now fits in there. you can also see the EP has miles of extra room in the route at the top of the guitar. also, i don't think you'd need a string retainer as the EZ top lok feature would still apply to the guitar. so, if you can figure out how to properly put an EP spring claw in there, it should just be a direct drop in.
but what worries and frustrates me the most is that there are probably thousands of EZ equipped guitars with this problem. i have played 4 (yes, FOUR) rg2550z guitars with this exact same problem and i don't see what is stopping all the other EZ RG's out there suffering from the same problem. i wonder if ibanez will realise this problem and smooth out the tolerances or something with future EZ's? i PM'ed an ibanez rep on the ibanez forum and he was helpful until i described my problem to him. i haven't received a response for over 5 months.
so, what do you think of all that? am i mad? it's such a shame because i love the edge zero to death! i love the stability of it.
