Edge Pro Problem (not pulling up properly)

valcian · #1 03-09-2009, 09:48 AM

Hi, just wondering if anyone can help me with this, it's happened before but I had a tech fix it and now that it's happened again I figure I'd like to know how to sort it myself.

When I pull up on the bar on my Edge Pro (in an rg1570) the pitch raises (as it should) but the block of the trem hits the body / edge of the cavity before the bottom edge of the trem can hit the foam lined cavity where it's supposed to go.

I've looked at my trem angle and it seems okay, and raising the action doesn't seem to help.

Pulling up from the open low E I get about 8 semitones of pitch increase (equivalent to the 8th fret pitch).

If anyone knows what to do about this I'd very much appreciate it.

Thanks in advance,

Valcian

...and you haven't enough yet!?! man, stop there, don't go further. anyway, it's not necessary for the bottom edge of the trem to hit the foam pad. also, raising the action will raise bottom of the trem even far from the pad. if you want the tail to touch the pad, you have to lower the action, instead. but really, you're going already too far with that pull-up, pal.

When I wrote it I did think "yeah, that's actually quite alot of pull up". But I've just had another look and although the low E pitch raises by around 8 semitones, the high E only raises by 3 (3 frets) which really isn't much at all.. hmm..

I've lowered the action back down, but that doesn't help at all..

that's even too much for a high-E. don't ask too much from your guitar.

it doesn't help because it's not the action height that guarantees you a wider pull range. because no matter whether the trem is set high or low, it will always be the same distance from the cavity, as it moves (the trem, that is) vertically, not horizontally. i told you if you want the bottom of the trem tail to hit the foam pad, then lower the action until it does. but it makes no sense actually, because you're limitating the pull range even more. the "problem" is the trem block hitting the cavity during pull-ups. you "should" route the cavity out of a few millimeters, so that the spring block wont hit it when pull the bar any longer.

but really, 8 semitones on the low-E is even too much. live with it.

Well the trem always used to hit the foam lined cavity, suggesting something is out of whack now, I also used to get more than 3 frets pitch raise from the high E, the strings used to fret out before the trem hit the foam lined cavity.

I wouldn't call it asking too much, I'd call it wanting things back as they were :P

Although i am kinda with Nuno on the fact that, you have PLENTY of travel, if you used to get more and now you dont, your studs have shifted, as the trem route wont have moved, neither will the trem block have distorted, only result i can think of, is trem studs moving/shifting forwards. if thats the case, it'll get worse and you'll have a hefty repair bill.

Oh, i just thought, are you using a higher gauge string set? the only other variable is you "thought" it raised more.

I'm using d'addario 9s as always, idk 3 frets worth of pitch raise on the high E just doesn't strike me as alot.. The edge of the trem used to hit the foam lined cavity and now it doesn't, that's the real problem here, the idea of the posts shifting worried me though :P

honestly, it's all i can think of

Not good

As I said, it's happened before and a tech fixed it, but didn't really tell me what was wrong, other than "the posts had dropped into the body a bit" the rg1570 doesn't have locking studs so idk if it's something to do with that.. I'm just hoping whatever it is it's not serious :P

Jem7RB MK · #10 03-09-2009, 01:18 PM

are you able to take some pics of the posts ? non locking studs maybe the key ?

The only way you hit the pad first is if the action is very low. The arm holder hitting in the cavity is the limit of travel on an EP. If your arm holder is loose and has turned and now the spring is hitting first might be the reason, if your arm holder isn't loose, it isn't.

valcian · #12 03-09-2009, 01:21 PM

Yeah, I'll take some pics in a minute, I'll do pics of the trem from the side, back (with the rear plate off) and show where it's pulling up to, just for the sake of completeness :P.

Noo, my post count isn't high enough to post images or links.. I'll pm you the links Rob

valcian · #14 03-09-2009, 02:43 PM

sent you them aswell rich, just to be sure :P

Jem7RB MK · #15 03-09-2009, 03:53 PM

hmmm, i looked and see nothing majorly wrong tbh, i'll let Rich comment (he'll be far better and diagnosing the prob) but he might take a few hours, he's normally really busy even when not selling stock

It just looks like the end of it's travel
