String Slide Mystery

I had my '97 360-12 with a 12-saddle bridge in storage for a few months. Today I got it out and the strings will not stay on the saddles. They slip as I try to tune it and won't stay put. I've never seen anything like this on any guitar. Any ideas about what went wrong and how to fix it?

Mystery Solved!
The R Tailpiece broke. I've heard of the dreaded "Exploding R Tailpiece" but never thought it would happen to me. (I never had a problem with my '66 when I owned it in the '70's...)
Are exploding R tailpieces covered under warrenty, or do I need to buy another one?

What strings did you have on your guitar?

I can see right now where this line of questioning is headed! :mrgreen: :mrgreen:

Not likely to have made a huge difference. R tailpieces are made with cheap pot metal and are inherently weaker than, say, a trapeze tailpiece.

No Paul, my line of questoning is definitely not headed in the direction of strings. That issue has been resolved. Obviously strings are not the problem.

Not true.

Looks like a fine time to bring back these old classics! :lol: :lol:

Color me skeptical, but I believe die cast from zinc alloy IS pot metal.

However, if someone would like to test it, it'd be really easy to do so. "Pot metal" usually has a much lower melting point than you'd expect from a higher quality alloy, so if someone has a broken R-tailpiece, it's simple enough to find at what temperature the remains melt, and compare it to the value of a high quality alloy (Handbook of Physics and Chemistry should have the value)

The failure rate is infintessimal. There's tens of thousands of these out there in perfect condition. Some do break but it's a very small number overall. Keys, pickguards, and pickups fail a thousand times more often.
I agree with this 100%, the number of R-tailpiece breaking is a drop in a huge bucket. I think the reason people make a big fuss about it is due to the fact the piece in question is under pressure (12 strings in this case) so there's a danger aspect, not to mention it being one of the flagship design elements of said guitars.

I take it "R's" are made of Zamak?

If the 'R' tails were really made of 'pot metal' (really just slang for cheap, low-temperature casts), they'd deteriorate and break on way more guitars than we've seen.

If I were CEO of RIC, I'd replace them for free after shipment of the broken one, but that's just me.

I've been using a custom SOB (Snake Oil Brand) 12 string set in gauges close to stock Rickenbacker strings. FWIW.

Temperature and quality aren't always at odds.

Zamak is a high quality alloy used for casting, with a low melting point, which allows it to be used on small intricate designs (like the R, which is why I suspect it as the material in question)

As you can see, there is more to Zamak than meets the eye...and "cheap" is not one of the words I'd use, judging from the above Wiki article.

The exploding R tailpiece just happened to my Carl Wilson 360/12.

I hadn't played it in awhile, and I took it out of the case and all the strings were WAY out of tune. I didn't recall detuning purposely so I was puzzled.. I started tuning it up and nothing would stay in tune.. I looked the guitar all over and wondered if the neck was screwed up etc.. I kept at it and all of a sudden BAM! the entire tailpiece flew off the face of the guitar and the strings with it. I was a shocking episode. I thought the neck snapped off. As soon as I realized what happened, I looked over the entire guitar and luckily no scratches or cracks. It couldn't be good for the neck for that to happen though.

Anyway, I contacted RIC and their response was basically send us the broken tailpiece along with $110 money order or certified check and we'll send you another one. The guitar out of warranty. And no comment about whether they've improved reliability of the part. I personally think it is really shoddy not to stand behind their product, and it's shocking, none the less, to not expect critical metal parts of the guitar to last indefinitely. It's outrageous. But there's no choice but to take their terms to get my 360/12 CW working again. The guitar was new in 2000...so the tailpiece lasted 18 years..
