[Harp-L] Need some crunch - Bassman 59 RI

["Bobby \" BlackHat\" Walters" <bobby@xxxxxxxxxxxxxxxxx>]

All,
 
I have a Bassman 59 RI.  I use it with a Green Bullet, JT-30, and my new
Fireball mic.  However, I just can't seem to get the crunch I want out of
it.  My tone is just too smooth for my taste.  
 
How can I get it to break up earlier.  Tubes, settings, what?  I'm currently
running 5U4  6L6  6L6  12AY7  12AU7  12AT7
