[Harp-L] stacking harp amps

[John Hegedus <johnhegedus@xxxxxxx>]

Can anyone tell me how to stack harp amps for a better sound like Mark  
Wenner's rig? I have a Silvertone 1481 and I want to hook it up to a  
bassman. I like the sound that the 1481 produces but I would like it  
louder and not quite a dirty as the 1481. The 1481 does not have a  
line out.  Any info would be greatly appreciated.  Also, how is my  
buddy and one of the greatest harp players in the Pittsburgh area  
(Frank Franz) doing these days doing?
