Supro S6420 Thunderbolt. An updated version of the original classic with and incredible tone! 35 class-A watts through a single 15″ speaker. Good condition with some tolex wear. This amp has thick, clear cleans and a sweet saturated breakup with a nice sag and compression. The 15″ gives provides a tight low end and also allows the 35 watts of power some breathing room. This amp sounds killer and is the perfect size and volume for both studio and live use!
