Vax 300 Piezo (or Other) Issue - Anyone Experienced This One?

Recommended Posts

Hi fellow vax users,

 

in buying my second variax (a 300 intended for a xplant) I found it to have an issue (no signal output from the 1/4" output) which I figured to be a jackplate problem. When playing live, I connect to my HD500 using a variax cable, and use the 1/4" out to go to Vocalist Live 3 for (ahem) assisting my vocal accuracy. My main vax is a 600, so the 300 remained on it's guitar stand unused (apart from the rare string breakage moment) for ages, while I awaited a replacement jackplate. This took 3 months via my line 6 service agent in Sydney.

 

I finally replaced that, and now I have an intermittent problem with output signal, even when I can tune it using my pod HD500, on selecting a patch from my gig set-list, I have no audible signal on the first E and B strings. I have connected it to workbench, and it SEEMS to wake up the signal failure problem and it corrects itself. Sometimes this takes a couple of connection and software start-ups, as there still seems to be a connectivity issue even with the new jackplate - workbench mentions switching off and re-connecting, as the connection has been interrupted. This seems to happen regardless of which of lead I use (I have three good ones).

 

After replacing the jackplate, I also ordered 3 replacement piezos (one as a spare), as this issue reared it's ugly head. As I was going to change the piezos over, I noticed the E piezo had come free from it's solder, so I just re-soldered it. I looked at the B string solder which appeared ok, but I re-soldered that also, thinking it COULD be a bad joint. I guess the next step is to install those piezos and see if that fixes the issue, but these ones onboard DO work - just not straight away. Also to my ears, the 300 doesn't appear to sound the same as the 600 - it just seems to be lacking something, like lower output or whatever.

 

On Saturday I connected to workbench and did a firmware re-installation, which appears to have done nothing to correct my problem.

 

So I just can't figure why it shows signal in the HD500 and allows me to tune those two strings, yet I have no audible output when a patch is selected. Whether it's the workbench connection, or I have the 300 connected long enough for the problem to adjust it's fly in order to feel comfortable with being seen AND heard in public - I'm a wee bit flummoxed here.

 

So has ANYONE experience this oddity and had it sorted?

 

Maybe I'll be ordering those Graph-tech saddles and doing a transplant, but if there are underlying issues with the main-board, or something else, maybe I'll be wasting my time and money....

A lot of us experience piezo malfunction. They were poorly designed and die over time because of how they sit in the saddles.

A ghost system would be a good idea if you want a permanent fix.

 

I believe the JTVs addressed this problem so they should be void of random piezo malfunctions.

I've seen plenty of piezo issues on the forums... but i've had the originals on my 600 since it first came out....(something like 8 years ago?)

and it was my go to guitar for years.... no issues.  i guess i just got lucky, or you just didn't :) probably lots of people in between.

I got mine in January, the guy said it was in great condition.

By the time I got it, it was fine until I tried to adjusted the intonation which sent my piezo into a road of flickering in and out of being quiet and buzzy.

 

I tried to fix the grounding by stuffing copper wire between the piezo and the saddle, which worked until I moved something on it.

 

During that time I had a new piezo but tried to use the old one as I was afraid it would sound different from the others (I ordered mine from LR baggs because I heard a rumor that Line 6 is ceasing stocking Variax parts).

 

I accidentally broke the old one's wire off when I tried to push it out as the copper wire jammed it in there really hard.

 

A few days back I finally soldered in the new piezo and it's perfect now.

Thanks to everyone for the helpful info....

 

@clay-man:

glad to hear the new piezo did the trick for you - I should be able to make time tomorrow to do the same (fingers crossed it'll do the trick).

I WOULD seriously consider the JTV, but the only one which I find remotely desirable (looks wise) is the 59, but I am a Fender fan and can't imagine the neck would be to my liking. The others just look positively ugly (IMHO), so the only option for me is a transplant into a strat clone body (SX Traditional Series - alder body, a tweakable neck complete with traditional slotted tuning keys). I plan to build a sexy reliced Fiesta Red as my main guitar.

 

By "ghost system", do you mean the graph-techs?

 

@TheRealZap:

My 600 still works like the first time I got it too, though the frets are needing attention. I figure I'll just use the neck from the 300 and shape it closer to my real Strat's neck like I did with the 600, and swap em over when it's time. By that time it'll be my backup anyway.

I agree. I think the JTV guitars are pretty visually unappealing as well. I love how my 600 looks, even if it is missing pickups. The 69's body is ok but the neck and headstock really push me away. I'd maybe get a 59, but as much as I'd love a LP style guitar, I'd think the 3 way switch would get annoying. In the end, I wish there was a tele JTV.

 

By Ghost I do mean Graph tech, yes. Graph Tech's ghost system piezo saddles.

They make an immense improvement in build quality AND sound.

I believe they're very close to the quality of the JTV piezos, which is why people say the JTVs and ghosts on a V1 Variax sound better. 

Ghost saddles also get rid of the unwanted quack of when you pick hard on most of the single coil and acoustic models.
