JTV89F selection switch

[malriley]

I just discovered that my JTV89F's model position selector switch had the same model selected for position 2 that position 1 had stored and so the model that was stored in 2 did not work. The same was for position 4 and 5, model stored in 5 was mirrored in 4. When I first got the guitar I tested the various model sounds in all the banks and positions and I think they worked fine. I never really did that again, and always assumed they worked. I did the latest firmware update using the Monkey, and never thought I should test them. I think this happened from that update. I realized it when I was making a new model in the Workbench HD, and noticed that when I moved the 5 way position switch on the guitar, only 1, 3, and 5 would only make the bank models 1, 3, and 5 highlight and change the model tone, but 2 and 4 would not select. I could double click on the 2 and 4 rectangles in the WB bank, and the guitar sound would change to what they were labeled as (OEM models) regardless of the position I had the switch in, but if I moved the switch from say, 4 to 5 and back after doing this, 4 in WB would not be selected. It was like it was a 1,3,5 switch. I think others may have the same results from the 2.23 update, but may not have found this out yet. I submitted a support ticket and wait for an answer.

 I don't seem to have any other issues with the guitar, like low volume on some strings, or funny sounds using some models. The selector switch seems to work fine with the alnico pickups, and I get 5 different neck and bridge tones so the switch could not be bad. Maybe check your guitar and see if you have the same issues. Any models that are stored in positions 2 and 4 are not available in each model bank and mirror those in 1 and 5 respectively.

Flash it again. make certain the LED's on the interface device are green throughout the entire update cycle.

If it starts blinking red near the end of the cycle, wait for it to finish, unplug, plug in again to reinitialize,... then Flash it again.

I have tried reflashing it, and the process works fine. I have tried older firmware versions and the switch still still does not select the 2 and 4 position models. I think it is something to do with the position switch assembly even though it works when the modeling is off and it just switches the coils in the pickups. All 5 positions work and have a unique sound when modeling is off. I believe the guitar was always like this since it was new, and I just never tested all the models to see if they were all accessible through all the switch positions. Line 6 support wants me to take it in to a local service business.
  Can you or anyone check your JTV-89 or 89F to see if your position switch functions as it should by trying the models in all 5 positions and see if they are different and what they should be when the model knob switch is ON?

Go to the pull-down heading for guitar servicing locations.

 

Sounds like it needs to be checked out by the Line 6 authorized service center in your area.

There are about four different things that can do that, so it needs to be check by a service center that knows the product.

I am sending it in to Line 6 rather than taking it to the local places. I think it is a selector switch assembly issue and has always been that way, but I never knew it. The guitar works fine and the models that I made and downloaded work fine as long as they are not stored in the locations selected by position 2 or 4. Those models work when selected through HD Workbench, just not through the position selector switch.

Check the top left corner in Workbench HD to see what the guitar label is, to be certain it is

correctly programmed for the guitar you have.

I ordered a replacement switch assembly that included the little pc board and replaced it myself (Line 6 service is closed) using my great technician skills. After testing it for different models tones in all 5 positions and checking that it did switch to all 5 using Workbench HD, I can say that the problem is resolved. The guitar works fine now. Part was ordered from fullcompass.com . I think the guitar always had this problem and I never tested it in all 5 selector positions to see if it changed tones. It wasn't until I used WB HD that I did not use much, I discovered I had a problem. There are two parts to the switch, one is for the magnetic pickups used when modeling is off, and one is for when it is on. The part used for modeling puts out different voltage levels for each position. Mine put out only three unique levels for position 1, 3 and 5. 4 was the same as 5 and 2 was the same a 1 when I measured the output voltages after installing the new switch I measured 5 different voltages. Glad it is fixed and working as it should.
