Previously called K & M Analog Designs, Two Rock was founded in 1999 by Bill Krinard and Joe Mloganoski and has become famous for their Two-Rock Guitar Amplifiers.

Every amp is built from scratch in their own shop and all components are hand wired and tested. These are high end amps.

Their products are gaining momentum and are currently used by such guitarists as Carlos Santana and John Mayer.
