Dream Rig Power Interruption

Hello Folks,

New to the forum.

This week I finally completed my Dream Rig with a JTV-69, Awesome guitar and the whole setup is just what I needed as I play in a church worship team which kinda works out as a cover band so all the Dream Rig options are perfect for my application.

I did have a problem this sunday though that concerns me.

First let me say that I was using the JTV without the battery using the supplied VDI cable to the HD 500 and L6 link to my DT25

During performance the power on my JTV flickered a couple times .

The real problem was that I was in a virtual capo mode and when it came back it defaulted to standard tuning. Catastrophic to say the least!

I have seen some hints of power supply issues on the web when using the HD500 to power the JTV but nothing concrete.

This did happen to me at home but I thought i bumped the cable or something and never in an alternate tuning so it didn't concern me. Now it does.

Any help or info would be appreciated.

 

Thanks

    Re: Dream Rig Power Interruption

    Heres an update to this issue.

    Since no one has chimed in I contacted Line 6.

    According to the person I spoke to this is not a common problem and was somewhat stumped by my description.

    He did say that Line 6 does not recommend that the included VDI cable be used in a live setting. It is only intended for programming. seems a bit bogus but whatever! I do have the upgraded cable on order but will not receive it for a few days due to backorder at sweetwater. in the meantime I am to use the 1/4" cable connection.

    Also I am to closely monitor if there are any more power interuptions using the battery and also once I get the new cable.

    so for now its a wait and see.

      I have the cable for the 'live' setting and it is a lot sturdier, almost too heavy duty. Never had any problem with the included VDI cable for about a year of home use though, but I never used alternate tunings. You mentioned that you use the JTV w/o the battery. Maybe that makes it more suceptible to short power glitches. I always have the battery in the guitar compartment, empty or not. Maybe worth a try. Also, you may have a faulty 'programming' VDI cable. It should not cause a short independent of movement or position unless its broke, obviously it can break more easily as its not built for abuse. Just a couple more ideas to check out. Hope you get over the disappointment that it failed you during performance. Bummer.

      Martin

        Thanks for the info Martin,

        I do suspect that the included cable should not be a problem and thanks to your input I was correct. I will follow their advise to the letter just to help pinpoint the issue .

        I actually thought about putting in the battery with the VDI but I was under the impression that the battery is not activated unless the 1/4 jack is used thus not active with the VDI, maybe someone can confirm this.

        With the lack of any other signs of this problem anywhere else I am really concerned that there is a problem with my unit. Luckily I have an awesome dealer in Sweetwater and they will make it right

        No way I'm giving up on this platform, it is too awesome to throw in the towel. either way I do have my situation documented at Line 6 and at Sweetwater, so if all else fails Ill get a new guitar.

          You should not use the included cable for anything other than updating the Variax or tweaking with Workbench. There is no protective shell around the connector that goes into the guitar, and in a short amount of time you will ruin the jack in the guitar. A very expensive repair... Only use a real VDI cable, you can find them online if you don't want the heavy Line 6 version.  The shell makes sure that the plug doesn't wiggle around in the guitar's receptical breaking the small contact wires. I believe that's why you were having dropouts. It's in the manual...

    Update,

    Well fellow riggers, unless I am celebrating too soon, I have found my problem.

    To my embarrassment it seems to have been a bad update on the JTV.

    Let me explain: during the last week the guitar seemed to work for the most part but did have a couple drop outs.

    Then on saturday I went to hook it up with the 1/4" cable and the guitar went crazy. Turning on and off, the lights on the switches were flashing, Just freaking out. I went back on line to do some research and came across the document on how to properly update the firmware on the JTV using the included USB converter.

    This is not how I done it when I first got the guitar. I had the guitar hooked up through the HD500 and when I ran Monkey it did show that the latest firmware was not installed so I let monkey do its thing and performed the update.

    So after the meltdown I decided to perform the update again following the documented procedure.

    Walla! the guitar has been a different animal. Solid and no drop outs with either the VDI or the 1/4".

    I used the guitar in Sundays Service without a problem

    In summary, I pray that this is it and no further problems creep up and just a note to anyone from Line 6 that the "Proper procedure" should have been more obvious or somehow not able to be performed through the HD500.
