Thank you for your purchase of a Two-Rock am-
plifier from K&M Analog Designs. As a discerning
guitarist, you know the road to great tone begins
with great components. Our classic design, care-
fully selected parts and hand-built approach
combine to make an extremely versatile instru-
ment. Please take the time to read this manual.
We hope it will answer any questions that you
may have. We extend a warm welcome to you as
a member of a select group of musicians who

We are proud to introduce what we humbly consider to be another
benchmark amplifier, designed and perfected in collaboration with John
Mayer. John has been touring and recording with Two-Rock amps since
early 2005, and it was only natural for us to join forces and build him an
amp that would meet his specific needs. Based on our Custom Reverb
Signature amp, the John Mayer Signature amp is a 100 watt, single channel amp with incredible depth, bandwidth, and soundstage.
We have added elements of the Sterling Signature, Overdrive Signature,
and Kimock Signature amps to produce pristine cleans with rich harmonics, as well as a sophisticated all tube spring reverb circuit, tuned to John’s
ear. We’ve moved the gain and master controls to the far right side of the
front panel, separate from the tone controls and reverb, to allow quick ad-
justment on the fly. A contour control has been added, allowing global fine
tuning of overall output EQ. And we’ve finished each unit in gun metal gray
carbon fiber covering, black cane grill cloth, and silver piping. Each amp is
individually signed by John, and is shipped road-ready in a Calzone road
case. Congratulations on you purchase of Serial #____ of 25!
