K & M Analog Designs, LLC was founded in 1999 by Bill Krinard and Joe Mloganoski. Both have long histories in music, sound, and electronic design. Their collaboration is driven by their desire to produce the best sounding guitar amplifiers available, and began with listening to, playing and tweaking many of the fine production tube amplifiers of the last 60 years.

Joe Mloganoski has been playing guitar for 42 years. At the age of 18, he worked a full time day job while playing local venues, at times 7 days a week. His tone quest began on the Boston area club scene. After making his way to the left coast he continued playing music in a variety of bands, always looking for that elusive killer guitar tone. He delved heavily into electronics, operating his own electronic repair business for 13 years before his true passion for music, guitars and tube amps led him to team with Bill.

Bill Krinard has been involved in tube amp technology for the past 40 years. During this time he has designed hi-fi tube amps and has spent countless hours tweaking production guitar amps. In addition, Bill has created several new and innovative circuits and applications for guitar amplifiers that have been copied by many. Already known locally as the tube-amp guru, his extensive knowledge of construction techniques and huge reservoir of tone secrets is unsurpassed. The design and production of K&M and Two-Rock amps has launched Bill and Joe to the forefront of boutique guitar amplification.
