Are you ready to take control of your amp?
Tired of having your ears bleed so that you can get to
your amps' "sweet spot"?

Our Vari-Watt boards are the prescription for great tone
at ANY volume.  This product allows your cathode or
fixed biased tube amp to be cranked to performance
levels without overpowering your bandmates.  Forget
cumbersome attenuators and step up to performance
AND tone.
We're located in Westminster Colorado, between Denver
and Boulder.  Our Engineering staff  is passionate about
music and making great sound.  If you're a tube amp owner
or builder, you're in the right place.
