Sound bleed through even When volume is down
« on: December 12, 2010, 10:38:44 AM »
Even when the volume is down I can still hear the magnetic pickups when I play, vaguely. Any clue what this could be?

You mean you have it on blend, turn the magnetics down all the way, and still hear them?  Are you running stereo or through the same amp?  Have you tapped the pole pieces with a piece of metal to see how loud  that comes through to make sure it isn't just some weird artifact with your piezo?  Simplest answer is throw that switch over and go piezo only.
Well...  THAT happened...

I'm only using the magnetic pickups(not blending), one amp, and I use a mono cable. The guitar in only 2 years old and I've noticed the 1st fret starting to lift also. A 2yo $3500 guitar needing a fret job and having electronic problems?!? I love Parker guitars but this is ridiculous! FYI... The battery has less than 20 hours on it. Should I call USM quality control?

Yes. The pot maybe damaged

I've had that happen to me lately. In my case, I think it's due to a floating ground issue. I was getting a shock from my in-ear monitor pack last night (it's not wireless and it was touching my skin). They are doing bad stuff like lifting grounds on things to try and get rid of noise, but it's creating other problems.

Anyway, do you have anything similar going on in your scenario?

OK, it was just a thought. Are the grounds in your guitar hard wired, or do some of the grounds rely on the cavity shielding for ground? My volume pot is not loose and it's hard wired to ground, but it's been doing that occassionally lately. But it's only for this show that I am doing where I know for a fact they have all kinds of floating ground going on. In fact the other guitarist's Guild Starfire III was acting funny yesterday as well. I think in our case, it's gotta be because of all these floating grounds we have going on. And I know that my pot is not bad, either. It works 100% as expected every time except lately at this show I'm doing until next Sunday.

I don't know what else to suggest in your case. You could try replacing the pot, maybe that's the culprit. Although, usually when a pot goes bad, it just gets really scratchy.

Maybe something you could try is some electronics cleaner on it. It might be a bit gunked up inside. Maybe I ought to try that, too...

My bad.  I assumed you meant bleeding through when you were playing piezo!  [:I]

So what are you playing with the humbuckers zeroed and no piezo?  Are you talking tuning between songs onstage?  How loud are we talking?  I mean loud enough that it could be mistaken for playing, or just loud enough that you notice it?

 I guess I'm wondering if it's enough of a problem to worry about.  If it's the tuning thing pick up a used TU2 for $30 bucks and with the bypass tuning, your problems solved for a lot less cash than having someone look at it.  

Or I guess my "switch to piezo only" advice still applies. Turn the volume down on that.  I mean every guitar has a quirk or two you have to deal with onstage.  This one doesn't seem huge unless there's a "Here's what you don't know" bombshell you're about to share.

Now the fret issue is a whole 'nother level[:(!] If you have to get that fixed, might as well get this looked at at the same time.
Well...  THAT happened...

I get the same issue - but only after playing thru my Bogner very loudly for a while - I think the sheer weight of tone it creates produces singularity and a wormhole   - so when I turn down my pickups - and indeed switch off the amp - I still get some amplified sound - presumably coming from the next universe along :-)

Seriously tho - sounds like  a pot - and is the 1st fret defintely lifting? or are you noticing glue underneath or maybe some spare by the side of it?

You may have a bad piezo/mag selector switch.  I just noticed a similar problem with my Artist... if I have the volume up on the piezo pot and my selector switch on Mag only and I hit the strings hard I am getting disortion... like the signal is "bleeding" through to the piezos.  If I turn down the piezo volume all the way, the problem goes away.  Or if I run it split or piezo only, it is fine.  If I flick the switch back and forth a few times, it goes away.  So must be my switch.  Sounds like this is similar to your problem maybe??

Parkers are notorious for terrible switches.  Squire Strat quality stuff [:(].  FYI I also had fret issues (frets lifting off board), and had to send my guitar in for a factory fretboard replacement and repair (and pickup selector switch fix).  The bright side of the story is the Parker folks did an AMAZING job fixing the guitar, really went above and beyond.  I was upset to have to send it in, but was happy with the result.  Now I am miffed my mag/piezo switch is going south, but figured it was just a matter of time since my pickup selector switch lasted only about 8 months.

I agree that problems like this should not happen!  Parkers are so brilliantly designed and constructed, but having crappy switches/pots/etc on such works of art is inexcusable!

That in theory can't happen because the switch is physically disconnecting the contacts, or at least it's supposed to. I replaced the switches in my guitar with a completely different types, and my mag pickup volume control occasionally will not turn down completely, and it only happens when I am a one specific "venue". It's absolutely not because of the piezo pickups, because they are switched off, and that switch is not in the middle position. It is physically impossible for it to happen with these types of switches.

Probably me and the OP have different causes for our problems, but I've identified the cause of mine. Don't really have a solution for it, though. And I don't get how it's happening, other than floating grounds are trying to find a path to ground somehow. Very weird stuff which I have not encountered before... [B)]

Interesting- thanks for the info, I am pretty ignorant when it comes to guitar electrical work.  Thing is, when I flick the selector switch (the piezo/mag switch) back and forth a few times it "fixes" the issue- like the switch is dirty or something. When it happens on my guitar, if I turn the Mag Volume all the way down (with the selector switch on Mag only) I still hear the guitar through the amp- faintly, and the timbre is that of the piezos- like a little bit of signal is "bleeding" through. Anyway, seems kinda related to the problem originally posed.  Hope you get it sorted out- and that Parker starts spec'ing better switches and pots.

Yeah, I don't know exactly what the deal is in your case. I sometimes get the same thing that you describe, but only at one location I play, and then it's not consistent 100% of the time while I'm there. Anyway, it sounds a bit like the piezo pickups because the treble bleed cap is still letting the highs through, but in an anemic sort of way that sounds yucky.

The problem for me with the stock switches is that they wouldn't reliably switch pickups 100% of the time and/or they would make scratching noises when you used them. [:(!]

Sorry Paul but the wiring doesn't disconnect the pickups in the switch. It grounds the pickups that are to be turned off but leaves them connected through to the preamp board. But that doesn't seem to be the issue here.

It sounds like the OP has bad pots which aren't fully grounding the signal.

Well, I meant disconnecting the pickups in the sense that it's grounding them out. But the stock switches do disconnect the "hot" path and switch them to ground instead. So it's physically impossible for both contacts to be "on" at the same time. Even if they were, you should get nothing, because it would be grounding the signal.

Anyway, yeah, it's probably a bad pot if the same thing happens every time no matter where he is physically.
