Greer Amplication Company is based in Athens, Georgia and is well known for its diverse boutique guitar effect pedal line. The Greer pedals are first class but the amplfiers are just as special. The Greer Apache is loudest and best sounding boutique five watt amp that we've ever heard. If you need more power, check out the Underdog 15 watt amp. If you need more than 15, the Thunderbolt 30 watt amp is the most powerful amplifier that Greer Amps manufacturers.
