NUX ACE of Tone Dual Overdrive Pedal stacked with Tubeman (Open Box) MKII and Morning Star

ACE of TONE is a dual overdrive pedal stacked with Tubeman MKII and Morning Star. 2 classic overdrive circuits in one compact enclosure.

Versatile modes and routing design to enhance the tone variety.

In the left corner - Tubeman with FAT mode. Tubeman offers way more clarity and gain than any classic Tubescreamer, and we modified the circuit with a useful secondary function by simply holding the foot switch - FAT mode. It cranks way more bass response to enhance the low-end yet makes the tone warmer.

In the right corner - Morning Star with SHINE mode. Morning Star is based on legendary Bluesbreaker circuit: very transparent, low gain drive. Like our Morning Star, it also features a simple FOOT SWITCH HOLD to engage the iconic SHINE mode. In SHINE mode, you can get way more treble sound to make your tone crystal-clear.
