DrSexBob Posted January 5, 2016 Share Posted January 5, 2016 Hey guys, Just got my JTV-69 and I've been playing with it constantly for the past 2 weeks! unfortunately I had a weird issue with my tone knob, no sound would come out of my Variax, rocked the knob back and forth had a bit of a crackle.... and now it works again! However! Now I've noticed that I cant control the volume of the guitar when in standard pickups via 1/4, yet volume works with modeling and works with VDI for Magnetic/Modeling. Any ideas that I can try will I just have to follow Line6 up! Any Reply would be great, Thanks! Quote Link to comment Share on other sites More sharing options...
psarkissian Posted January 5, 2016 Share Posted January 5, 2016 Intermittent contact internally to the circuitry. Rocking the knob back and forth will just loosen the chassis ground contact, adding to the intermittent and crackling. It could be as simple as a loose retainer nut under the control knobs, or something more deep in the circuitry that has to be troubleshooted by an Line 6 authorized technician in your area. Go into your Line 6 account, make sure your device is registered and log a ticket. Quote Link to comment Share on other sites More sharing options...

Or its just a dirty pot... 0.47 seconds and 4.2 cents worth of plastic-safe contact cleaner could easily solve the problem. It's worth a shot, and is exceedingly unlikely to make anything worse. http://www.amazon.com/CRC-Plastic-Contact-Cleaner-Aerosol/dp/B000BXKZVA%3FSubscriptionId%3DAKIAILSHYYTFIVPWUY6Q%26tag%3Dduckduckgo-d-20%26linkCode%3Dxm2%26camp%3D2025%26creative%3D165953%26creativeASIN%3DB000BXKZVA Quote Link to comment Share on other sites More sharing options...
psarkissian Posted January 5, 2016 Share Posted January 5, 2016 cruisinon2,... normally I would agree with you. But in this case, if he is able to rock it back and forth, then there is something else going on that contact cleaner won't fix. Sounds like loose hardware contributing to an intermittent chassis ground. I've seen this malady and dealt with it before, that's why I know. Otherwise,... good call, would've been might first suspicion too. Quote Link to comment Share on other sites More sharing options...
psarkissian Posted January 5, 2016 Share Posted January 5, 2016 Oh, and plastic safe contact cleaner,.... couldn't hurt. Carefully pull the Volume and Tone control knobs up and off, put some plastic safe contact cleaner on a cotton swab, let a drop or two drip go down the shaft into the inner workings. Turn the pots back and forth a few times to work it in. Couple drops to each shaft is all it needs. Quote Link to comment Share on other sites More sharing options...
DrSexBob Posted April 27, 2016 Author Share Posted April 27, 2016 Thanks for the replies guys! In the end I've just left it for now I did as suggested psarkissian however I think it may be a solder job! I use VDI %80 of the time and magnetic Volume control works however! If i started using 1/4 jack more though than I would action it however, living in Australia leaves me wanting to wait it off until the Line6/Yamaha thing as settled, I've noticed heaps of retailers how changed stock levels etc and that could also mean the repair centers will change but alas!
