"Colby Amps brought both versions of their 2-channel amps: a twin 6L6, 50-watt version and a quad 6L6, 100-watt version. Both feature two independent channelsяone is designed for huge cleans and the other is a higher-gain channel designed to bring a player's preferred distortion voicing in reach. Retail for the 50-watt is $3,800 and the 100-watt head is $4,200."
