Vibro King
new customshop series
Total rebuild preamp, and back to the orginal, to get rid of a
typical Swedish terrible modification.
Unfortunately there
are a lot of Fender and Marshall amps around Sweden, with this
amateurish and disrespectful modifications.
It's a real amplifier
sabotage.
Cables and components
are very chort and strech mounted, and seem to be soldering with a iron
or lighter, rear and back panels are tattered with drilled holes placed
slantinggly and also in the panel letters. |
