A bad case of 'knob touch' - Page 2

The kife edge must be at a 90-degree angle with the pivot screws, paralell with the body.
That way, you cannot tighten/loosen the springs at the back, for you will influence negativelly the sustain, tone and playability of the guitar.

The problem here is that it's a little subjective! (ie as far as I can gather, it's not an exact science - since you can't see the bit that needs to be exactly 90 degrees!). Wouldn't you think they'd have a better way of informing when you're at 90 degrees exactly?

But in any case, making this adjustment in my situation must simply be correcting an already out of whack setup, as I can't believe Ibanez would design it where the trem arm hits the volume knob (albeit a rather tall knurled telecaster type knob as fitted by Ibanez)

That's what I thought.
It can't be a major design flaw! So... what the h*ll is happening here?

Any answers?... (No neck shims, please!)

Why the animosity towards the easy fix? It is not at all uncommon for Ibanezs to need a neck shim to allow the trem to sit at the right height. Personally, I don't see it as a design flaw, though I'd prefer it if the neck pockets were cut so this wasn't necessary.

As an experiment - just push the very rear of the trem down with your finger...it only needs to be pushed down about 2-3mm there for the trem arm to lift (away from the body) by about 1cm.

Therefore I reckon you're in the same situation as myself...presumably there's been a different gauge fitted since the trem's zero point was last set properly.

The guitar is perfectly set up. It's an Edge Pro, not a ZR nor Edge Zero.

I guess I'll give it a try with the neck shim... not that I'm very pleased to do so... but...

If the bar is hitting the fully seated stock volume knob and the trem is level.... you must have very limited pull up range on that guitar.

Mine is a double edge pro (an edge pro with piezos in the saddles)

No! As a matter of fact, the pull-up range goes all the way until the trem arm almost touches the rear of the body!!!
I have never had a guitar with such a low profile! The bridge is sitting really low into the body. Reminds me of a FGM.

This page helped me greatly...

The sixth photo down in particular. My viewable 'slither' of metal was at an angle - as soon as I got it parallel, my trem arm is about 1cm clear of the volume knob (as it passes over it)...so no more knob touch here!

Man... it is paralell! (I mean, I do know how to setup a FR and an Edge trem!!!)

>> (I mean, I do know how to setup a FR and an Edge trem!!!)

Like I would know that?

I was just trying to be helpful, but since you're getting arsey ......if you are so good with guitar setups, then why are you asking how to sort one out via a forum?

To the point, if your trem *is* really setup perfectly, & yet the trem arm is still hitting the volume knob - then there can only be one of three possibilities....

The trem arm is bent out of whack (towards the body)

The volume knob is set too high.

The hole in which the trem arm mates with is too deep (or the bit of the trem arm that's goes in the trem unit hole is too short!)

I guess there is a fourth possibility...Ibanez have designed a guitar where the trem arm is meant to hit the volume knob!

Crazy_Guitar · #28 06-23-2008, 08:34 AM

I have replaced the original trem arm with a Lo-Pro Edge and it still touches.
I wonder if the the Edge Pro has a deeper hole than the Lo-Pro Edge...

The volume knob is 0,5mm from the body. However, the volume knob is really high! (Tough it's the original one...)

I just tightened the trem springs slightly when the arm of my RG20th trem touched the vol knob. I cetainly wouldn't go shimming the neck because of it. Just tighten the springs a tiny bit.

That's exactly what I said...just be prepared to be told that the trem unit is setup perfectly, it's parallel & he knows what he's doing.
