Product Description


Nux NDO-5 Ace of Tone Dual Overdrive Effects Pedal

The Ace of Tone is a dual overdrive pedal effects pedal that combines the best features from the Nux Tubeman MKII and the Nux Morning Star. The 2 overdrives have always been favourites having their tones stacked.

To the left, you have the MKII sound which is a high gain overdrive giving you more bass response. Over to the right, you have the distinct SHINE of the Morning star which is a low-gain drive that gives you more room for your treble and making your tone clear.

The Ace of Tone has True bypass circuitry and has a toggle switch to modify how the 2 overdrives stack on your signal chain.

Great pedal

I bought this hoping it would be an all-purpose overdrive for home noodling into a little Blackstar HT-1R. I’m still experimenting but first impressions are good and I think it will fill that role pretty well. The Morning Star / Bluesbreaker-style side provides the kind of bluesy sounds I was after but never could coax out of the HT on its own, at least not at low volumes. Does some nice classic rock tones too. I probably won’t use the Tubeman / TS side as much but it’s a handy switch-up for grins, especially in fat mode. I also probably won’t play around with the stacking order, but that will be a nice touch for some. It seems really well built – feels solid, the pots and switches are all smooth, low noise, and it looks great in an understated kind of way. The paint finish maybe isn’t as smooth as some, but it’s glossy, thick and looks like it will take some knocks. I like the jacks on the top because it’s easier to hide the cables and it looks neater on the floor/shelf (no pedal board, just this and a tuner). The only minor criticism would be that I’d prefer all the knobs to be the same style as the bigger drive knobs with the clear white stripe marker because they’re much easier to see in low light or from an angle. And, I ordered it on Monday night and it was delivered in Brisbane on the Thursday – awesome service from Artist.
