AMPLIFIER MAINTENANCE
Besides the normal replacement of vacuum tubes/valves, your amplifier should require very
little maintenance. However, if you notice a change in the performance or the sound of the
amp, or if have any questions regarding your amp's performance, please contact your
authorized Gibson Amplifier Service Center.
From everyone here at Gibson, we thank you for trusting your tone to our amplifiers and
hope you take as much pride in playing them as we have in designing and building them.
