Let's get clear on some history and info...: Ted McCarty joined Gibson in 1948. TM became Gibson's vice-president in 49, and president in 50. Seth Lover was already involved with Gibson before Ted joined Gibson. Seth Lover was hired by Gibson in the early 40s to basically troubleshoot Gibson amps made by a Chicago based amp manufacturer. In 1948, Gibson released a new line of amps, the GA series, that would be build in-house at their Kalamazoo factory. Seth Lover had a lot of input into the designs of the in-house amps. Some of the cabinets for these amps were outsourced. The in-house built GA series amps were discontinued in '66 or '67 during the same time that Seth Lover and Ted McCarty left Gibson. The Norlin era started in '69.
