The Lab Series L5 is a 2x12" solid state combo amplifier made in the 70s featuring Gibson & Moog technology.
Part of this amp's fame comes from BB King, who has been using Lab Series amps from time to time.
The L5 has a very impressive clean tone, considering it's made in the 70s. Today's modeling amps are so much more advanced, but there's something to be said for a simple solid state combo like the L5. It does one thing good - producing a nice, clean tone.
