JohnK Duality+ - This is John's significant upgrade to the Duality. What all did he do? I don't really remember, exactly. It's got the two fuzz voices like the original circuit, but he also added a Gain control and the switch flips between Mid frequency adjustments on the Filter knob. It's like an incredibly versatile Duality, which was traditionally not very versatile. Gets super synthy with the Gain rolled off and the Duality turned all the way to the right. Or, you can crank the gain and turn Duality all the way to the left and it just screams. Or, you can set it however you want if you buy it, it'll be yours. I'm fairly positive this is the only one JohnK ever made. No box, but has Velcro
