Supercool
 

And more Jack, this time on his Alembic....
 

I loved his Alembic 72-001 Sound !  ____  It is great to see him still playing with vitality in the first vid .

I haven't seen that video of Water Song before; that was great!  Thanks!

Check out that pile o' speakers in the Water Song vid - wow.
 
All that fire-power supplemented by two Marshall 4x12's...oooof.
 
Contrast that with the rather modest rigs shown in the Funk vid.
 
My how times have changed.
 
72-01 sounded great, BTW.

True that, 72-001 in Jack's hands is awesomely powerful!  
The first video he was rockin'.  
 
Love that guy.
