GTS (Grand Tour Series)

The GTS is the ultimate hi gain 200w power house and the Dynamo Flagship amp. It was specifically designed for professional touring and to push modern high power speaker cabinets with an unreal amount of clarity and punch while still remaining tight and focused. It features a high gain structure matched to a high definition output transformer that has awesome string to string definition that really shines on progressive rock and metal music, 7 string and drop-D tuning, and a clean channel that sounds amazing for Jazz and Country playing covering a large spectrum of styles. It is built using audiophile grade components, has a custom Toroidal power transformer similar to those found in pro audio concert power amps, and has built in power filtering to reduce electrical line noise common in live venues.
