hot 6L6gc tubes in fender bassman 10 with homemade overdrive/boost

Jamming around with my buddy's original Bassman 10 silverface with "75 watts rms" label and original 10" fender speakers. No overdrive or gain channel on the amp. Needs a little work but provides those authentic tube harmonics. The video focuses on the 2 6L6GC output tubes and the associated blue plasma. Master on 10, bass channel volume somewhere north of 5, bass mid and treble controls dimed. The compression on the recorder cuts some of the bass, but believe me the drywall and ductwork in the basement were rattling. The "bark" of the amp is provided by my prototype homemade overdrive unit (JFET buffer with over 3V 1/2W output). I might call it the white dog or tone dog or something like that due to the "barking" tone it pushes. Derek and the Dominos Crazy Horse Black Sabbath AC/DC Rolling Stones
