pickup .vs. models huge volume difference

[Frankg111 0]

Team,

 

I have a problem where the pickups have  very low volume output .vs. the modeling.   I mean it's like pickups volume level 3 modeled volume level 10.

 

1. I have re-flash firmware with 2.23 no change

2. re-flashed 2.20 no change

3.  Left battery out for hour, put it back in no change

4. Tried VDI and 1/4 cable into Helix/PowerCab same issue

 

Any other ideas?

JTV-69S  thank you for the reminder.

 

I recently had the battery box replaced under warrantee 

[psarkissian 355]

I'll shift this to the correct category.

Either pick-up height adjustment or a short somewhere pulling down the line.

Break any strings lately?

 

[Frankg111 0]

I have not broken any strings.  I did try raising the bridge pickup quite a bit the other day.  Nothing rattling around either.   Can I look for the shot to do a bit of self-analysis?  Could the jack be futz up?  it was just all of a sudden there.    I did re-string a while ago but all the ball ends were there.  I would have gone hunting if one was gone. :)

 

Any other ideas?  I don't want it back in the shop again.

[psarkissian 355]

All accounted for ball ends,... good.

So at his point, sounds like set-up issue or some short pulling on the mag pick-up circuit.

 

Don't mess with it, leave to a pro. These are not the passive electronics of our grandfather's guitars.

It's a whole other cat, and you have to cuddle it under the chin in a different way.

ok  so off to the shop again?  Is that your suggestion?

[psarkissian 355]

Yes.

All too often, someone will go into one of these guitars, realize they got in too deep,... then it ends up on my bench.

Best to save time and trouble and get it done by an experienced Line 6 authorized tech right off.

Psarkissian,

 

Update to the story.  I decided to take a look around in the guitar last night. Maybe new strings, etc.  Just to see if there was anything obvious.  Bit of a rattle,  however I know there are no ball ends.  Took off the back cover plates,  nothing.  And yeppers millions of circuits and molex connectors, etc.   Just for fun, (Yes I know my way around computers and circuits -- static grounded myself btw) pulled the pickups molex, and re-seated it.  Boom all good. Pickup output back where it was.   

 

Me think that there was a bit of oxidation on the molex pins and receivers.   So back in action.  Very odd,  not sure why that would happen however it's something to put in you basket of tricks.

 

If that didn't work,  then it was off to the shop.

 

Thank you.

Connector was probably cocked just enough to make intermittent contact.

Sometimes it can look like it's in and lock when it isn't as fully inserted as it looks.

I see that every now and then. Fortunately, it not a common thing.

 

Back on track, rock-n-roll!

[Frankg111 0]

one thing,,,,  is that connector suppose to be locked in?   or is it just press fit and friction?   It pulled out of the connector with very little resistance,  like none!

 

If the connector secure clip is buggered,  it may worth getting it fixed. or coming up with a solution.

 

Thanks.

 

Still learning here.

[psarkissian 355]

Lock, but not a hard lock.

 

[Frankg111 0]

ok thank you.  I think it's ok then!

[psarkissian 355]

Psark,

 

The problem has reappear.  It's not the connector at this point.  Must be on the board.  I am not sure what to do so I am sending it off to an authorized service center that serviced another problem with the battery box.  Do I need to open a ticket with you all or should I just let the center manage the problem?

 

Thanks

[psarkissian 355]

Log a ticket. Something is odd there. I'll check with them on this.

Psakissian,

 

Follow up on chasing the bug.   So here is part of what I found.   The connectors seem to have oxidized a bit.   When I went to the authorized repairs shop we  pulled all the top board connectors.   There are only three on the top board. No disassembly just took off the cover.   Used Deoxit 100,  brushed a bit on lightly.   reset the connectors a few times.  Most of the problems seem to have disappeared. I suspect there are a few more connectors on the bottom of the board,  i just don't want to disassemble it.  

 

So for the last week there has been no difference in volume levels modeled or passive.   

 

Just wanted to follow up with you so you have some new info in your arsenal.

 

Thanks

Rare, but it can happen.

well, I guess I am just that Rare person!!!!   :)
