For your consideration .... a great trio of gear that offers a creative and unique grouping that sways deep and swings wide. The heart of the system.... https://en.wikipedia.org/wiki/Roland_VK-7 The pulse of the system ..... https://www.premierguitar.com/articles/motion-sound-srv-112-rotary-speaker-cabinet-1 The power .... A vintage Yamaha KS531 keyboard amp .... 270 Watts - loaded with a 15", an 8" and a horn. 4X inputs. The amp section can be unplugged from the drivers and be used to power other units. Controls somewhat scratchy. Great quality and projection. Has more character and strength than the Roland KC line of amps. Will be in Victoria 12/18 - 12/25 to offer viewings.
