After Upgrade Switch Is Malfunctioning

Recommended Posts

Hi guys,


Have a JTV-59.

Upgraded to the latest firmware and tried it out.

Think I have to tweak my POD hD500 a little.


Have a gig in a few days so I went back to the older firmware. Need some time to tweak which I don't have the coming days..

Now I have an iupgrade which I don't like at this moment and a switch which is malfunctioning


My friend is always saying: if it works and you are satisfied, don't upgrade. Wish I had listened to him


Someone any ideas or having a simular problem?

Have you checked the well-known problem of the knob going too far down the switch? Take the knob off (or at least raise it) and see if the switch works then.

unfortunately, this is by (bad) design.


people have resorted to putting a piece of carboard/paper/plastic under the knob, at the top of the shaft. This fixes the problem.
