Risson Amplifiers are designed and built by master engineer, Bob Rissi.

Bob Rissi is a Master Designer and Engineer, with over 50 years of experience creating amplifiers for the brightest stars in the music industry.  Bob obtained invaluable experience in 1961 when Leo Fender hired him to work on his latest models, and today his honed expertise shines through with every note that blasts from a Risson Amplifier.  

After leaving Fender in 1967, Bob became Director of Engineering at Rickenbacker, where he designed the famous TranSonic series used by Led Zeppelin, Jeff Beck, Steppenwolf, Cheap Trick, Strawberry Alarm Clock, and many others.  Bob left Rickenbacker to start Risson in 1970, where he built a variety of models that were purchased by renowned musicians like Slash, Lita Ford, Poison, Motely Crue, Al Perkins, Glen Campbell, Rick Vito, Joe Walsh,  Rick Nelson, and countless others. 

His incomparable artistry is now available to you with Risson’s new tube amplifiers.
