This 1964 Princeton blackface is a transition model.
 
It is in fact a Princeton brownface with black tolex. It has 4 control knobs like a brownface opposite to 5 control knowbs on a "real" Princetone blackface
It has the sweetest tremolo you can find.
 
This amp is called the "Tuxedo" model because of white control knobs on a black face and black tolex.
 
Amp is in great 100% original condition (recone original speaker) with also original footswitch.
 
Amp is 110v with external transformer supplied
Just serviced and ready to gig
