John East J Retro Bass Preamp in G&L JB Basses

The John East J-Retro is my favorite on-board bass preamp. It has killer warmth and is still growly. I’m playing two G&L JB basses. The JB5, Alder body & Ebony fingerboard, has stock G&L pickups and GHS Super Steel strings and the JB4, Ash body Maple fingerboard, has Seymour Duncan Quarter Pounder pickups and GHS Super Steel Strings. The bass was recorded direct through am A-Designs REDDI straight into a US Apollo and into Logic Audio.
