Line 6 Flextone III sound test after fix

This stereo flextone amp came in the lab with faulty pots and switches.
It came in for the first time a couple of months ago, hoping that a deep clean of pots and switches would last at least a couple of years, unfortunatelly it lasted only a couple of months.
We proceed to replace all pots and switches and cherry on the cake we fixed the stereo returns that someone in the past had disabled.
Hope we will never see it again for at least 5 to 6 years.
