Reloading the firmware is a temporary fix. On the 300 & 600, the circuit board is encased in a metal cage. With the fluctuation in temperature, humidity, etc., the circuit board being this close to the cage is causing the problems. The fix is, to take the Variax apart, shield the cage (black electrical tape, non-conductive paint, what have you), reassemble and string. Your problem will be solved. Look up discussions on the Dreaded Coffin Shielding or such. Good luck!

thanks a million mate!!!
I opened the chasis, and actually just tape sheielded uder the main circuit board and the corners of the model selector knob.
I did not disassemble the whole unit. But in the past 3 days I have not had that annoying problem any more!!!:-)
there were a couple of inductors almost touching the metal, and I'm guessing those could be the most problematic units.
But now the guitar is playing just fine and hopefully it will stay that way. Now the only things remaining are to figure out
a better palm muting solution with the piezzos and to get some locking tuners...

I'm here again. POed and perplexed...
well the annoying model selector problem is back again, though less frequently.
I really really would appreciate if someone would kindly send a photo showing which parts of the coffin
need to be shielded. Should I dissassmle the model selector knob and also shield around that as well??
Any assisstance would be hightly appreciated as this is driving me crazy.
I really like the feel and touch of this guitar and also the versetality. Otherwise I would have sold
it already with so many design flaws
thanks in advance

The entire metal interior of the cage/coffin. That should work. Be careful and don't unplug any connectors if you can help it. The problem is not the model selector knob... it's the circuit boards... I used liquid electrical tape to paint the entire interior of the cage/coffin. It stopped the problem, but disconnecting all the connectors, cleaning them, and putting them back caused some other problems. Also, NEVER put the batteries in incorrectly. The Variax is not very forgiving and you could halt the ability to use the batteries without service center repair.

Greetings, and sorry to hear about your problem. There is another possibility ... although it's more likely the coffin-shielding will correct this, I have had a problem that's similar to yours with BOTH of my model 700's selectors. Since your problem seems to occur more often around SOME model settings versus ANY model settings, I'm thinking that you should try this. It's simply a procedure, no parts or repair required. Here is my document's link in the Line 6 documents pages (and even though it's titled for model 700's, the Model Select knob design is more than likely similar if not identical in your 600):
I'd be happy to hear your feedback and/or suggested corrections if the procedure can be further simplified or clarified.
