MakeItShredNo1 Posted August 14, 2015 Share Posted August 14, 2015 I have a chance to score a JTV69 for a steal, but the model knob is "broke." According to the seller, it seems "stuck in the on position" - I imagine he really means that it's stuck non-depressed, but I can't be sure, as I will not be able to play the instrument before purchasing it and having it shipped to me. I've seen a couple of topics on common problems, but let's say worst case scenario - how much is it gonna cost to fix this if it is the worst possible problem? And if I can't do it myself, what's a ballpark on the labor (which will of course vary from tech to tech - just a round-about number of what I could expect to pay)? I'm curious if this will end up being a good deal that the guy just doesn't want to mess with, or if I should just buy a like-new one.

stevekc Posted August 14, 2015 Share Posted August 14, 2015 Very typical issue - even "new" JTV-69's suffer from this - fixed by gently lifting "up on the Model knob - to allow proper up/down travel for the "push"push" switch action Quote Link to comment Share on other sites More sharing options...
psarkissian Posted August 14, 2015 Share Posted August 14, 2015 stevekc suggestion is a good place to start. He knows his stuff. One of five people in the Americas (north or south) I trust to do a mod on a JTV, ... without messing it up. Work on one of his Bigsby JTV-59's,... ... nice. If it's in the "on" position, chances are it's just an alignment thing. If the volume of tone control knobs are loose, then it's just a matter of pulling off the knobs, testing the knob excursion for each position is good, then tightening the nuts down. There is also a spacer fix for that. A Line 6 authorized service center could deal with that or get a knob with the in it. Being an authorized service center, they would check out all the other things as well, as they would have access to service info and service manuals. Both of the above mentioned are simple and straight forward. If the encoder is jammed underneath, the pick-guard would have to come and that is a bit more involved. There could be a couple of reasons for that, including a failed encoder. In any case, it should be looked at by someone who knows the product. At this point giving a ballpark idea would not be possible until a better idea is regarding the above mentioned possibilities. They are just too wide and varied. BTW, what's the serial number of the JTV-69? Quote Link to comment Share on other sites More sharing options...
MakeItShredNo1 Posted August 15, 2015 Author Share Posted August 15, 2015 I got the owner to reply - he said not only does it seem "stuck on" but that the model select knob doesn't turn at all. I'm not sure if he means that it's difficult to turn, or impossible to turn. He also says that the model selection is functional when connected to a HD500 - the knob doesn't work, but the actual modeling is functional. I don't suppose that narrows down the diagnosis? Assuming I can handle the simple repairs myself - like wedging paper underneath the knob, like I've seen mentioned on this forum - is it now possible to ballpark me a "worst case scenario"? Or still too many variables? Quote Link to comment Share on other sites More sharing options...
Charlie_Watt Posted August 15, 2015 Share Posted August 15, 2015 Sounds like the knob is damaged rather than just not working. Worst case you can replace it. Not that big a deal if you can steal it. Quote Link to comment Share on other sites More sharing options...

MakeItShredNo1 Posted August 19, 2015 Author Share Posted August 19, 2015 Thanks for all your help guys. I think unfortunately I'm going to end up passing because there are too many variables, and ultimately I'm G.A.S.ing harder for a Helix with only so much money to go around. If it was surely a simple and cheap fix I'd have to consider it, but I've been burned by used gear a few times lately and don't feel like the headache right now. Plus, the only certified Line 6 technician in town is super overpriced, so if it did need a repair I can't handle, I'd be out serious money.

marnott Posted January 8, 2018 Share Posted January 8, 2018 Hi, I'm having difficulty with my JTV 69. I'm trying to tighten the tone control knob. It seems impossible to take off the front of the pick guard like on a regular stratocaster? I've removed the pick guard to reveal underneath? However I'm still unable to see any means of tightening? The tone control is not functioning properly. Does anyone have any ideas on how to replace or repair this? I've been performing full time with this for about the last 2 years. It's a great guitar. Wouldn't use anything else. Only recently I've been experiencing these issues. Cheers Matti Quote Link to comment Share on other sites More sharing options...
