Nux

The story: a Chinese maker under Cherub Technology

Nux operates as NUX Effects under Cherub Technology CO. LTD, the parent company named on Nux's own product pages². The company describes itself as "an innovative musical instrument brand" that has built several well-known pedals and multi-effects⁴. Its catalog runs well beyond guitar pedals, spanning amplifiers, wireless systems, electronic drum kits, digital pianos and pro-audio equipment¹.

The name itself is part of the company's story. Nux explains it on its own site:

Known for: TSAC and DeepImage amp modeling

Two modeling technologies define Nux's digital pedals. The first, TSAC (True Simulation of Analog Circuit), was introduced in 2010 "with the sole intention of bringing Amp Modeling to a whole new level"⁵. It has since evolved into TSAC-HD, which Nux describes as high-definition white-box amp modeling that captures the dynamic response and harmonic intricacies of analog amplifiers⁶. TSAC-HD appears across the MG series of multi-effects, including the MG-300⁵ and MG-101⁶, and in the Amp Core Studio, where Nux says it "delivers authentic amp feel with ultra-responsive playability"⁷. A further development, TSAC-4K, powers the Solid Studio MKII, modeling the preamp and power amp separately and reproducing what Nux calls the tube amp's negative feedback response⁸.

The second technology, DeepImage, is Nux's proprietary DSP-based modeling designed to capture an amp's gain structure, non-linear distortion characteristics and spatial air⁹. It also works in reverse: the MG-50Li can capture the essence of your own amps, preamps, overdrive and distortion pedals and store them as NUX Image profiles through the NUX IMAGE app¹⁰. Firmware updates have added DeepImage models to the Amp Academy Stomp, including models based on the XTC and CAE 3+ channels⁹.

The range: stompboxes, tuners, loopers and multi-effects

Nux's guitar catalog falls into a few broad groups:

• Multi-effects and amp modeling: the MG series (MG-101, MG-300, MG-30, MG-50Li), the Amp Academy Stomp, Amp Core Studio and Solid Studio MKII⁶⁵¹⁰¹¹
• Reissue Series stompboxes: compact analog-style drives and delays¹²¹³¹⁴
• Tuners: the Flow Tune pedal tuner and the Strum Tuner¹⁵¹⁶
• Accessories: the NSP-10 sustain pedal and the Pedal Topper, a colored cap for marking looper and tap-tempo switches on a pedalboard¹⁷¹⁸

The Reissue Series is the brand's best-known stompbox line, and Nux itself calls it the bestselling series¹⁹. It covers the main gain and delay types:

These sit alongside Nux's wider stompbox catalog, which includes overdrives like the Drive Core, Morning Star and Horseman, distortions like the Fireman and Metal Core Deluxe, delays like the Tape Core Deluxe and Duotime, modulation like the MOD Core DELUXE and CH-3 Chorus, and the Cerberus multi-effects pedal.

Support through nuxaudio.com

Nux runs its product information, firmware updates and documentation through nuxaudio.com, where each pedal has its own product page with specifications and manuals³. Firmware updates are a recurring part of owning a Nux digital pedal: the Amp Academy Stomp's V2.0.5 update, for example, added six new DeepImage amp models to an existing unit⁹. Manuals for pedals such as the Strum Tuner are also available through the manual library linked from its product page¹⁶.
