The 1959 Bassman on the right is the only amp on.  The revamping consisted of changing the tail resistor from the factory installed 10K ohm 1 watt to the later Fender version, 6.8K ohm 1 watt resistor.  This together with putting in the correct bass potentiometer of a 1M audio taper, instead of the factory installed 250K linear pot (may have been a factory mistake), made a world of difference.  The amp has more gain, the tone controls more dynamics and balance.  It's pretty darn nice.  I've got to thank my friend at Grammatico Amps for pointing out the discrepancies between this amp and the holy grail 5F6-A that Fender settled on when they decided to reissue the Bassman.  I did have the OCD on the whole time but believe me, the amp could do this by itself in spades if I could turn it up past 3.
