begging the group's pardon for going further off....

The tube rectifier reacts differently than SS.  If your Bassman had an 
SS rectifier, it would sound (for lack of better term) quicker 
responding than your tube rectifier (GZ34?).  The voltages will be 
different too.  This will affect the tone, for better or worse.

The tube also introduces some `sag', which is appreciated tonally.
There have been circuits designed to reproduce sag using zeners and/or 
resistors but I haven't had any exposure or experience with them.

A fair amount of guitar players use their amps as tone generators, as 
opposed to devices to accurately reproduce their instruments at louder 
levels.  We tend to *like* distortion, especially the more aurally 
pleasing output tube distortion   [BLASPHEMY!!!!]  :)


Most here know more than I do about the actual electrons involved, so 
you'll probably get better/different answers in moments.  Either that or 
they'll decapitate me for deliberately distorting an amp or being one of 
those audiophools who can tell the difference between cable brands just 
by listening :)
