Here is a demo of my 1982 Lab Series L5. This is the same amp BB King uses on stage. These were also used by Kings X. The Lab Series amps were developed by Bob Moog for Gibson parent company Norlin in the 1970s. They feature a solid state design with a very tube-like tone and an interesting EQ section which allows you to dial in the exact midrange characteristics you prefer.
