This amp was hand built by Bill Krinard, co-founder of Two-Rock. He built this amp specifically for John Mayer, but it never got into John's hands.

As Bill tells the story, this amp is a mix between a Dumble Dumbleland Special and a Two-Rock John Mayer Signature. It has all of the John Mayer Sig sounds, but with more oomph - and a lot more headroom. This amp never made it to John, because after Bill made the amp, the folks at Two-Rock decided it was best it wasn't sent to John so he wouldn't end up falling in love with it and playing this amp instead of his Signatures on stage.

Truly a one-of-a-kind amplifier, made specifically for John Mayer. All hand built with NOS parts.
