Two classic overdrives to stack, in one pedal. The NUX Ace of Tone (NDO-5) stacks two overdrives: Tubeman MKII, with more clarity and gain than a classic Tubescreamer, and Morning Star, a transparent low-gain drive based on the Bluesbreaker circuit. Each side has a hidden mode you reach by holding its footswitch.
