Both channels of the“Blackface” and “Silverface” Showmans have “Bright” switches, so we use the Input
switch for this and the active input’s gain control as our “Volume” control, with the inactive control set to
maximum. This amp’s Normal channel has a fixed Mid, where the Vibrato channel’s is variable, so keep
this in mind if you are going for authenticity.

The late “Tweed” Era Twins were dual input amplifiers, so there’s no ‘wrong’ setting of the Input Switch
and Bright and Normal gain controls. This amp also has a full “Vintage Fender” 3 band tone stack, so
those controls don’t need any special attention for accuracy either.
