The NUX NDO6 Queen of Tone Dual Overdrive is a dual overdrive pedal, part of NUX's Verdugo Series of stompboxes. It carries two different but complementary drive circuits in one enclosure, and its routing switches let you set the order in which they hit your signal: MS into HM, or HM into MS1. For a player, that means two gain stages on one board slot, with the flexibility to decide which circuit pushes the other.
What it does
The pedal's core idea is two overdrive circuits that can be stacked in either order. As Pedal of the Day put it in their review, "By using the versatile routing and toggle switches, you can adjust the order of the overdrives: MS->HM or HM->MS."1 Running the circuits one way versus the other changes which circuit acts as the boost into the other, which is the usual appeal of a dual overdrive: the same two circuits, arranged differently, give noticeably different stacked tones.
Controls and switches
Beyond the two drive circuits themselves, the NDO6 has two switches that shape how it sits in your rig1:
| Control | What it does |
|---|---|
| Routing/toggle switches | Set the order of the two overdrives: MS->HM or HM->MS1 |
| BF/TB switch | Toggles between Buffer-Bypass and True-Bypass1 |
| IFS/NORMAL switch | Engages the INPUT FET STAGE (IFS) to increase the input signal in order to reach the amp's break1 |
The BF/TB switch is worth knowing about when you build a board: buffer-bypass can help preserve your signal through long cable runs, while true-bypass removes the pedal's buffer entirely when the pedal is off. The IFS switch is aimed at players running into a tube amplifier, adding gain up front so the amp's input stage is driven into its breakup point sooner1.
What reviewers said
Pedal of the Day reviewed the NDO6 in April 2023 and came away positive on how it fits into a rig1:
"It plays nice with other pedals, sounds great through various amps and has just the right amount of grit on tap to keep"1
