  1. Yes, Workbench can help. -Fresh string set, a 10-42 (or 46) gauge string set, for good string to piezo tension. -With a cotton swab, drip isopropyl alcohol onto the piezos, let it seep down onto the saddle. Then blow it out with canned air. Repeat as needed. This is to clear any gunk out from between the piezos and saddles, as the saddle acts as a chassis ground for the piezo circuit. Gunk in the saddles can make that an intermittent ground.
  2. There is a fix for that. A space cut just for that, or a replacement knob. A Line 6 authorized service center can take of that. https://line6.com/find/service_center/ If they have any questions they can find me through the usual service tech channel.
  3. Could be a guitar that's been acclimated to another region's climate (temperature and humidity) before ending up Down Under. Have that temperature and humidity issue with Stevic MacKay's JTV-89 and his Shuriken Variax guitars when he and Twelve Foot Ninja are in Los Angeles and I services his guitars. As I recall, he's from Melbourne. Sounds like that shim worked. Very Good.
  4. Line 6 Central is the current application for connecting with on the Downloads page. https://line6.com/software/
  5. No. Contacts, current draw and the power management circuit inside are different. So that would be a problem for the Variax and the battery charger. And there is something different about the circuit in the CS or Cameron-Sino batteries that claim to be Line 6 replacement compatible, but are not. I have had problems with those, damage to the Variax jack plate circuit, problems with the Line 6 battery chargers, and such. So those are not recommended, and advise against using those,... for now. --- If the situation changes with those, I'll let everyone know.
  6. A Line 6 VDI to USB interface device is needed to connect the Variax to the computer,... if you don't already have one. Line 6 Central works with Sequoia, but Workbench HD only goes up to Ventura. Un périphérique d'interface VDI vers USB Line 6 est nécessaire pour connecter le Variax à l'ordinateur,... si vous n'en avez pas déjà un. Line 6 Central fonctionne avec Sequoia, mais Workbench HD ne va que jusqu'à Ventura.
  7. From Google Translate,... I just bought a used JTV-69. I'm not really familiar with emulated guitars. Workbench HD is not supported by my Mac which runs on Sequoia 15.2. I downloaded Line 6 central but I can't do anything more. No interface appears allowing me to model my guitar, record open tunings. I'm a bit lost... what should I do? Thank you for your answer...
  8. Is a third party device not vetted by Line 6,... just so you are all aware.

  11. Reminder,... v1.71 and original Workbench will work, but v1.71 will not work with Workbench HD.
  12. No,... you would have to use original Workbench. And that runs on 32 bit machines (Mac and PC), not the 64-bit versions of the newer computer OS's. To run on Workbench HD, the v1.71 would have to be update to v2.00 or beyond. Would need an older computer or a board swap to a current version Main Board. A Line 6 authorized service center can do that.
  13. Loose internal connection would be the first suspect. Line 6 authorized service center is the best option to narrow it down. They will have the experience with the product.
  14. Spider IV line is much older than 5 years. And modeling products (whether L6 or others) are a different beast, being both an analog and digital hybrid. Most generic products can get generic 1st party or 3rd party spare parts. And that's hard to do generic 3rd party parts when the product has lots of patented and proprietary elements in it.
  15. Log a Support ticket in your account. There may be some battery compartment door parts still around.
  16. 1) "Do you think that a local repair centre (non Line 6) could check this out for me?", not a good idea, as they won't have access to service info including any tech bulletins there might be for it, parts and me (or Yamaha in Europe) for any further advice they might want. 2) That is an old product, long time out of production, so parts would be limited, so what is still available would be for authorized service centers and repair.
  17. Have a Line 6 authorized service center in your area check it out, there are five in Spain. https://line6.com/find/service_center/ The first suspect would be cold or oxidized solder points on the processor or DSP on the main board. And have them check tech bulletins for that. I would expect a couple of solder points to be oxidizing after this many years.
  18. 10 year old tubes,.... sounds like it's over due for a swap out of all of them, and a biasing of the power tubes. Have it done at a Line 6 authorized service center. https://line6.com/find/service_center/
  19. Spray was probably not a good idea. It is sounding more like it may be a a couple of solder points. Have a Line 6 authorized service center check it out. https://line6.com/find/service_center/
  20. MIDI timeout error. Memory buffer or an interface device may be involved in the error. Check connection and any interface devices. Put the amp portion of the unit into on,... but in Standby mode. Disconnect any USB hubs, connection must be direct to the computer through MIDI to USB interface,... and then try again.
  21. Workbench HD for JTV, Standards and Shurikens using firmware v2.00 or later. For original Workbench you will need an earlier computer or a 'look back' software application to use original Workbench, since it is out of date with current 64-bit processing of today's computer OS'.
  22. Take them to a Line 6 authorized service center in your area. They can check it out and have experience with Line 6 products. Self repair is not recommended and is ill advised. https://line6.com/find/service_center/
  23. "... could it be the Tubes?", maybe. Depends on the age of the tubes and playing time of the previous owner. Also depends on whether or not they are the specified tubes and bias. Review my posting on tubes in DT series amps. Review my posting on tubes in DT series amps.
