Ampeg amp

Andy Summers reportedly used an Ampeg guitar amplifier (of unknown model and vintage) early in The Police's career alongside a Fender Twin Reverb combo. This was during 1977-1978, until Andy switched to using his own Marshall amplifiers in February 1979.

According to photographic evidence, however, Andy definitely used an 'Ampeg was the Horseshoe Tavern concert on 2 November 1978... Which was most likely a rented amplifier.

Producer & engineer Nigel Gray recalls Andy using two amplifiers on Outlandos D'Amour, one of which was an Ampeg...

It was at least used on the Outlandos D'Amour album before he switched to using Marshall amps in January 1979.
