There were only two reasons I could come up with why those lights and controls wouldn't work:
#1) A connection came loose
#2) Bad quality control
None of two options made me feel good about purchasing that amp model again.
I understand at least the Fender Mustang III is fixed in the v.2 version. I already own the Mustang 1 so I know a little about what to expect and always liked the Mustang 1.
Anyone else have trouble with the VYPYR VIP 3 or that series?
