UV70p's Edge-Zero II-7 bridge

Hi just coming from here http://www.jemsite.com/forums/f16/ib...fr-133058.html ,
Pulled the trigger for the UV70p Universe!
I read some negative online reviews about Edge-Zero II-7 bridge. How would you rate it? Will it be reliable and durable? I am no stranger to fixing, setting up floyds. I have set up and even repaired two of floyds of mine. Where are the weak points of this bridge? Maybe the knife edges ?

Re: UV70p's Edge-Zero II-7 bridge

The major problem with all the EZ's is there is no steel saddle lockdown plate and you can strip the treads in the baseplate setting intonation. That's bad, don't do it.

Thanx Rich,
You mean I will have to follow the one-finger rule when fastening those saddle bolts? Be more cautious than this? Or simply never touch them?

If this happens, Is there any remedy to this? except buying a new trem? Would a solution with e.g. Helicoil work?

Anyways, i haven't paid yet. Should I do it? Should I buy this?

Re: UV70p's Edge-Zero II-7 bridge

Just don't over-tighten the bolts and you won't have a problem.

Thanx bro, that means, just turn them with my right little finger, (cause the left one is stronger i guess )

Re: UV70p's Edge-Zero II-7 bridge

I've stripped 3 now and I don't overtighten anything.

Yes, helicoil is the answer if you can get somebody to do it, but if you strip one hole, don't touch any of the rest, they'll probably go too. I don't believe the metallurgy is equal with all the batches.

Thanx Rich,

Don't you think the helicoil repair (or a variation) would be doable if someone does some practice on a spare plate?

so for 880 EUR new, would you think this is a good deal to go for?
And if i buy it, should i "stress test" it in the first month (while in the 30 days return period) and return it if broken?
Or should i just be careful during the 3 years guarantee and then never touch any saddle intonation bolt again?

in short should i buy it or not?

Re: UV70p's Edge-Zero II-7 bridge

Alright guys, so if it breaks after the guarantee, is there any Gotoh/Floyd Rose direct fit replacement for this bridge? Or am i supposed to buy the whole thing for some 300 USD? (and hope it doesn't collapse again)

Re: UV70p's Edge-Zero II-7 bridge

Hey, looking at the bottom of the plate :


wouldn't be possible to just glue a steel plate with a matching template from below - or just an individual nut, and then use the same metric bolts, just a little longer to bite the extra steel/or nut beneath?

Re: UV70p's Edge-Zero II-7 bridge

A great idea! Would be quite a bit of work. You would also have to make sure you have enough clearance from the bottom of the baseplate to the body.

In any case, as Rich pointed out with the issues with the bridge, I got rid of all of my J Custom and Prestige guitars that I had with the EZ Bridge. I liked it a lot at first but then I started having issues with one of them after a few years. Then the next guitar went south on me. That was enough for me to move back to Edge Pro guitars. No issues since.

That is a great idea. You could use the unused intonation bores to screw a new steel plate to the bottom.

You would have to recess the area of the body between the anchors to accommodate the depth of the new plate and any fasteners used. This would be a great fix for a stripped plate, but I wouldn't do it until one of them WAS stripped.

Conversely, If you knew a machinist you could get a steel plate recessed into the base- then the original intonation screws would be fine.

Re: UV70p's Edge-Zero II-7 bridge

It's gotta be 2mm thick so that's a lot of height to overcome with neck angle, but it's doable. You can use an edge plate on a 6, but not a 7 unless all the screws were in the front holes, and the B saddle on a 7 will always be in the rear hole. Since a machine shop would have to make the plate to begin with, helicoil is the logical answer. Helicoil all the holes and you'll never have to worry about it.

Re: UV70p's Edge-Zero II-7 bridge

So, I suppose a better Ibanez MIJ tremolo or an after market tremolo e.g. OFR 7-string or FR 1000-7 string is out of the question?
Does it require serious mods/routing?

Re: UV70p's Edge-Zero II-7 bridge

Another solution maybe ? how about using rivets? drilling out the hole and attaching from below smth like a rivet :


with a tang strong enough to keep the saddle down.
