NUX released firmware V2.0.5 for the Amp Academy Stomp on September 14, 2026, according to the maker's product page. The update adds Neural Amp Modeler file loading, six new amp models, a modulation effects block and several workflow shortcuts, and discontinues the Monarch editor software.

The NAM Loader accepts up to 30 community-shared Neural Amp Modeler (.nam) files on the Amp Academy Stomp, the A2-Lite NATIVE and the A1 CONVERT¹. Six DeepImage models are added: I XTC CLEAN, I XTC BLUE, I XTC RED, I CAE 3+ CLEAN, I CAE 3+ CRUNCH and I CAE 3+ LEAD. NUX describes DeepImage as its proprietary DSP-based modeling technology, designed to capture an amp's gain structure, non-linear distortion characteristics and spatial air¹. A Mono Octave effect joins the EFX block and a NU SHIM shimmer reverb joins the RVB block. A new MOD block carries 13 modulation effects: CE-1, CE-2, ST.Chorus, SCH-1, S.C.F, FLANGER, PHASE 90, PHASE 100, U-VIBE, VIBRATOR, TREMOLO, ROTARY and HARMONIST¹.

Delay time in the DLY block can now be set in milliseconds or BPM, switched with the EDIT encoder. The Global EQ shows a real-time dB readout while parameters are adjusted; NUX notes it applies at the output and affects every preset¹. Shortcuts: holding footswitch A opens the tuner, holding B opens the LOOP page, and holding C opens the footswitch assignment menu, which exits after 3 seconds of inactivity. Pressing the EDIT encoder opens a second page of that menu for assigning a connected dual footswitch such as the NUX NMP-2 or NMP-2 LITE¹.

With V2.0.5, NUX has discontinued the original Monarch editor for the pedal. The maker states that the NUX Audio app version pairing with the firmware is V1.1.7.1, and recommends uninstalling Monarch after updating¹.

The pedal's listed specifications are unchanged on the page: 27 factory and 27 user presets with 3 scenes, 9 effect blocks (NG, CMP, EFX, AMP, EQ, S/R, IR, DLY, RVB), 60 factory Cyber IRs and 40 user IRs, a 2.86-inch color LCD, USB-C audio at 24-bit / 48 kHz, 48 kHz / 32-bit sampling, minimum 2 ms system latency and 9V DC power at under 500 mA¹. The page lists firmware V2.0.5 and a separate version 1.3.0 without saying what the second number refers to¹. No price is given on the page.
