Difference between SuperLead and SuperBass

[macula56]

does anyone know what the differences are between SuperLeads and SuperBass amps? I can't find a schematic for a SuperBass anywhere. If anyone knows where I can find a schematic for one I would appreciate that info. Thanks, JMac.

SuperBass is similar to the 5f6a bassman/JTM45. 
 
SuperLead changed a few component values to make the lead channel brighter.
