Substrate Engineering

Andy, owner of Substrate Engineering, is one of the top Pro Audio dealers in the Sacramento area. He does all of the sound work at the Crest Theatre, and numerous other venues in the Central Valley region.
Substrate offers many reliable pro audio brands, including Genz-​Benz Electronics (a division of Peavey Corporation), and he is also a service technician who can repair amplifiers and loudspeakers.
I’ve bought several speakers over the years from Andy, had two amps repaired and a couple of speakers re-​coned… He is a virtual fountain of knowledge, having worked for some of the music industry giants in his career as a sound equipment specialist.
