I've got an RG2027X that I love to death. She's a rare bird--a fantastic playing and sounding 7-string.

However, the knife edges have taken a real beating over the years. Both knives are dented pretty badly after years of string pull and abuse, and it's a real chore to keep the Double Edge in tune now. I also can't intonate the low B anymore. The saddle has been moved back as far as physically possible, and the string is still sharp. I suspect it's because the knife edges are so dented, the whole tremolo is now sitting too far forward (toward the headstock).

I've read Rich's "Sharpening Knife Edges" tech article, but I'm not sure if that's appropriate in my situation. If my suspicion about the dented knives causing my low B intonation issue is correct, filing out those dent's won't help that particular problem.

What are my options here? I used to love playing this guitar, but because of the tuning and intonation issues, it now just sits unplayed.

Blocking the trem would solve the tuning problems, but not the intonation problem.

I'd want to see close ups of the edges.

Will do. Might be a couple weeks before I get to it, but I'll post some closeups here asap.

Okay, time was on my side today. Here's the knife edge pron...

That's about as bad as I've ever seen. Can't hurt trying to file them but you may have to swap all the piezo over to a different baseplate.

I do have an LPE 7 here that's in mint condition, but it's one of the old black models, not cosmo.

I'll keep trying to locate a cosmo baseplate, but I'm pretty sure I'll have to just use this black one and live with the mismatched hardware. Not preferable, but I'm more concerned with making this guitar playable again.

Changing neck to body angle by shim, will ask for higher bridge and bring back range for intonating low B.

Interesting. I didn't think shimming a neck added much, if any, string length. But, I'm willing to give it a try since it's a pretty easy thing to do.

Back to Rich's suggestion about swapping just the baseplate...

I figured this would be somewhat complicated, but straightforward enough that I could pull it off with my moderate skills.

Now, I'm not so sure.

I spent about an hour last night trying to get a good look at how the Double Edge is put together (without actually dismantling it). Hard to do since the piezo wire is short enough that you can't really get the trem out of the body very far without unsoldering it from the circuit board, which I don't want to do yet. Also, you can't get a clear view of what Ibanez has done with the 7 piezo saddle wires on the trem itself because they hold everything secure by wrapping black plastic around the sustain block (with all the wires underneath).

Regardless, I was able to see enough to know that I may be in over my head.

Man, those piezo wires coming off the saddles are so thin and delicate, and Ibanez has weaved each one through the back of the baseplate. Then, there's the stuff hiding under that black tape--which I won't know unless I unsolder the main piezo lead from the circuit board, pull the trem, and cut off the tape.

Just thinking about it makes me sweat.

Not counting myself out just yet, but I definitely need to think about whether I'm ready to tackle this. Once I do, there's no turning back.

 

[Rich]

I never said it was going to be easy

All the wires go to one buss line IIRC.

Remember shotgunn mods, used to do all the piezo work on these, converted edge pro's etc. If you're over your head I'd reach out to him to do the job.

Can you change only blades taken from other baseplate? They should go out by using some good pliers.

 

[Rich]

You can usually work the curved one out, good luck with the flat one.

Funny you mention Shotgunn. He actually did a piezo mod on an Edge Pro 7 for me about 6 years ago... and I was able to find this photo from that mod. Probably a good indication of what I'll find under that black tape...

That actually doesn't look too bad. I'm a little less scared now, and might try to tackle this over the weekend.

I should be okay as long as I take a boatload of photos while I'm disassembling and desoldering the Double Edge, and as long as my other LPE baseplate doesn't require any kind of metal work (e.g. drilling holes). Best I can tell, the individual piezo wires are just threaded through the back spaces, where the fine tuners are. Can't see any extra holes or anything, but I won't know for sure until I dive in and start taking things apart.

please, how are the piezo wires simply threaded into the backs?

Blocking the trem would solve the tuning problems, but not the intonation problem.

will request higher scaffold and bring back range for intonating low B and how are the piezo wires just strung into the backs?

Necro-update (because I recently got a message asking for an update).

I never got around to fixing this issue (only option was a complete baseplate swap), so I sold the guitar. I got lucky, actually, and someone found me via Instagram and was not only in love with the guitar, they were 100% okay with these issues. Buyer said he was confident he could fix it (and he did).

It was tough letting this guitar go, but I was really happy it went to someone who would appreciate it, fix it, and then actually play it. He was someone who'd owned a 2027X but sold it, and had regretted the decision for years. He was pretty ecstatic to get the guitar...chewed-up knife edges and all.

now those are some schnappsed knife edges. the bar side is supposed to be curved and the other side is supposed to be straight. looks like this thing has had some hard use or poorly mounted.
