Well, Carl still spends time listening to his vinyl collection and is still happy he created the Purple Moon, but he wanted to bring this pedal up to 2019 standards. The new 2019 Purple Moon has the Level Depth and Speed controls of the old model, and yes it still has the silicon Fuzz chip with Fuzz and Level controls that allow you to add mind bending Fuzz to that sweeping vibe and yes, this is still the only analog, true bypass Vibe/Fuzz pedal that takes you back to players like Hendrix, Trower, Gilmour or Anastasio....but it's smaller...cooler! Carl eliminated the second speed control in order to save space and reduce the footprint, but he packaged the new Purple Moon in a two-toned, anodized diecast case with head mounted Input/Output/9v and the same heavy duty bypass switch that he uses on every pedal. The Carl Martin Purple Moon uses special CM developed DC/DC converter circuitry that enables us to run the pedal with +-12V internally (which is necessary to maintain quality and headroom) while still powering the unit with a standard 9v external power supply! Bigger sound, bigger tone, all analog, all Carl Martin!
