About Us


Ron Jacobson – Owner/Manager


Ron Jacobson founded RBJ Productions in 1987. Originally located in Northbrook, the studio moved to Vernon Hills in 1991 and then to its current home in 2004. Ron discovered his love for studio recording after years of playing guitar, keys and drums in live bands. “I had the opportunity of recording projects at Streeterville and ACME studios downtown and I was hooked.” MIDI was brand new in the mid 80’s and, being somewhat of a computer geek, Ron immediately became very active in Chicago MIDI users group. He taught seminars on using computer-sequencing programs at CMUG meetings. “Our first studio was called MIDI Magic and we specialized in combining computer sequencing with 16 track analog recording. We had some great projects and great artists with a strong emphasis on sound design and innovative synthesis.” As digital recording emerged in the early 90’s the studio added 16 track digital tape based recording to the analog tracks and later upgraded to a 24 track hard disk system.

Today, the studio uses ProTools HDx and Logic based hard drive recording with unlimited tracks and amazing sound quality.
