RJM Music Technology, Inc. was founded in 2003 by Ron Menelli. Ron started playing guitar in 7th grade and only months later built his first effect pedal. After getting degrees in Computer Engineering and Computer Science and then spending several years in the corporate jungle, he decided to go off on his own and start RJM Music.

After playing guitar for many years (and becoming a guitar gear freak in the process), it became clear that there were certain needs in the market that were not being met by existing products. This became the focus of RJM Music and the basis for the product line.

The first product, the Amp Gizmo, was released in 2005. Since then, a total of 12 products (and counting) have been released and numerous custom projects have been produced.

RJM Music is best known for their cutting-edge MIDI foot controllers like the Mastermind GT and the Mastermind LT. They are also well known in the pedal board controller market with the Mastermind PBC.

RJM continues to develop new products with a focus on ease of use and versatility, and aims to build the best products possible for musicians.
