• 200 watt Marshall Major into 4-12 FluxTone cab
  

  "Ye Olde Leaf Blower"

  

  Steve Demonstrating the Major with all the knobs dimed out, and the VMT control on 0. As you can see all the people are having a normal conversation, while the major is pumping out about 250 watts! In a moment he will turn the VMT control up for just a few seconds, Then everyone scatters...like leaves in front of a "Leaf Blower"

• New Fender Vibrolux
  

  New stock Fender Vibrolux

  

  Outfitted with a pair of FluxTone's P10R's Note new power entry for amp is on the Custom VMT control box.

  

  We installed the VMT control in a separate box, no need for any new holes in the amp!

• 1967 Fender Twin Reverb
  

  We got this cabinet from Eric Johnson (still have the shipping label) Then we put this great old Blackface Twin chassis in it, with a built in foot operated (VMT) speaker controller. Hey Eric, you want it back?

  

  Ok, we put a couple holes in this one. The red switch eliminates negative feedback. And the other hole (by the power outlet) is for the foot controller. If you unplug the foot control cord, the amp reverts to normal mode.

  

  Nice hefty pair of FluxTone's C12N's

  

  Close up of foot control entry.

• Mesa Boogie with a single 12
  

  Used to have just the one setting.....Very Loud. Now with VMT you can still keep that famious sustain yet be dialed down for smaller venues, recording studios, band practice, ETC. Then when you are on the big stage...dial it all the way up, and blast away.
