I have a mid-60' Fullerton Studio (no 1st valve trig) and have compared it to a friend's LA model. Same horn to my ear, bright as the mpc you pop on, cool as you want it to be. The difference? Age and provenance and price. Zig Kanstul was at the Fullerton plant and I think we all know that he knew what he was doing.
I also happen to have an early Fullerton Olds Recording that is as good as any Recording model I've played.
