It is not even Christmas, but my Z-Best just started "jingling". This sound is most noticable on clean settings. On the KT-45 setting of my 6545 or when I set either SRZ I have to low gain, here comes this very distracting "jingling", on certain chords and many notes.
The sound is much like the sound when two good wine glasses are touching and a strong vibration hits them. In fact, when I started hearing the sound, I went through the cupboard moving wine glasses. Not long after I realized the sound was coming through the Z-Best. When I switched the same head and guitar on the same settings to the Rivera cab I have, the jingling was gone. So I'm sure it must be the cab.
I took the back off and checked the connections to the speakers and tightened them with needlenose pliers. I also tightened every screw in the cab. The ones holding the speakers on were not all that tight, so I made them tight. I also tightened the input jack.
Guess what? Still jingling just as much. Any thoughts?
(BTW, I was using my Dean V guitar, which has 2 Dimarzio super distortion humbuckers...jingling occurs no matter which pickup is selected and no matter how I set the tone on either the guitar or amp. Would like to try with another guitar, but my Strat got stolen on Saturday.)
Any advice appreciated!
Cheers, Blair

So my girlfriend listened to this and she prefers to call it "chirping". I can agree with that description, but it is not a quick sound, but rather one that remains constant while the chord/note rings.
Cheers, Blair

Is your amp on top of the cab? A microphonic valve might make a clinking sound. Maybe try putting your head on the floor and see if it stops.

Hi Neil, I did think of that, so I tried moving the amps off of and away from the cab. Didn't solve the problem. I also tried my Mesa 50/50 stereo amp with one side through the Rivera and the other side through the Z-Best. This amp is housed in a heavy rack case a few feet behind the Z-Best. In this test, the Rivera sounded fine, but the Z-Best still had that "jingle". I'm puzzled . Cheers, Blair

would almost have to be a speaker. try to distinguish wich speaker its coming from. also, i understand that you shouldn't tighten the nuts on your speakers more than finger tight. hope this is helpful.

1) take the head off the cab as suggested. 2) try one speaker at a time in the cab. 3) try the cab with a different amp. 4) take the cab to another room and play the setup. 5) if one of the speakers is dodgy, try it in another cabinet.
"jingling" and "chirping" is quite different to me but, oh, well. i've track some external noise down to the tube holder with 2 springs, the one with a metal circle that goes over the tube and 2 springs attached to it. it was used for the GZ34/5AR4 in one of my amps.
hope this helps...

If it's a speaker it's probably a dragging voice coil. This would be most noticeable as a low note fades out.

I have a problem with my Z-best (bought in 1998). It's one with the removable rear panel. It buzzes when you play near the "G" note on the low "E" string at the third fret. I tried all the above and eventually figured out that the frame with the grill cloth was buzzing! It's held in by drywall screws from the inside. I tried everything I could think of from installing weather stripping to felt to whatever, and couldn't stop it. I finally just left the screws out and have to remove the panel when I play loudly (which is all the time) PDW

Thanks to everyone for suggestions. I'll give them all a go and report back - hopefully with good news.
Cheers, Blair

Mudskipper, I have the same retainer (with the springs) on the tube rec in my KT-45 and I get an obnoxious rattle when I hit my strings (its more prevalent when played softly). Mine's a combo so the tubes hang downwards, and the tube socket for the rec is a bit loose. How did you fix yours?

Mine's a combo so the tubes hang downwards, and the tube socket for the rec is a bit loose. How did you fix yours? sometimes, simply applying a little more tension on the spring by shortening the length of them helps (this has worked for me). you can also wrap the ends (where the springs attach to the top and bottom mounting points) with heat shrink tubes. more drastic measures would be to either eliminate it all together or replace it with a clamp with teeth (like on Fender amps). hope this helps,

My Z-best I bought new earlier this year made an intermittent jingling rattle noise when I first got it. Two of the sheet rock screws where evidently stripped when they built it and fell out in shipping to me. One screw stuck to the magnet on the V-30 and the other wedged down in between the voice coil and frame of the speaker. By the time I tracked it down the speaker was ruined. I'd double check to make sure all screws are accounted for inside.

Hi there, It is actually present when the note/chord is first struck, remains constant for awhile, and then disappears as the note/chord loses power and fades out. Also, it is not audible at "apartment levels", but kicks in at a decent volume. Cheers, Blair

Then it's a mechanical mystery. Something loose somewhere. You're sure it's not something else in the room vibrating?

It is one of those paranormal that took place. Is there anything metalic stuck to the magnet ,may be ?

Well the mystery is solved (in part). The jingling was coming from the G12H speaker. Once I replaced that sucker, bingo - no more jingle bells. BUT...I have no idea what went wrong with this speaker. I'm no expert, but I've examined this thing quite closely and there's certainly nothing that shows itself to the naked eye. Nothing out of place, no metal stuck to the magnet...looks like a perfect speaker. So still a part mystery, I guess???
Cheers, Blair

Oh, i just thought of this while i was reading your above post..... check your center dome (also called the dust cover) of the offending G12h-30. examine carefully to see if any part of it has come apart from the cone. you'll have to gently try to lift the dome up. or you can carefully push down on the perimeter of the dome.
