NUX released firmware V1.3.0 for the Amp Academy Stomp on August 21, 2025. The maker's product page lists V1.3.0 as the firmware version and states that it is compatible only with NUX Monarch Software V1.0.3.1¹.

The Amp Academy Stomp is a digital amp modeling and multi-effects pedal with 27 factory and 27 user presets, each preset holding three scenes, and independent left and right IR slots¹. NUX lists nine effect blocks: NG, CMP, EFX, AMP, EQ, S/R, IR, DLY and RVB, with free or parallel routing order¹. Amp modeling uses the maker's TSAC-4K algorithm with separate preamp and power amp simulation, and the stereo Cyber IR engine runs at dual 1024-sample resolution with 60 factory and 40 user IR slots¹.

Hardware includes a 2.86-inch color LCD at 960 by 376, an aluminum extrusion chassis, buffered bypass, and balanced 1/4-inch TRS outputs¹. NUX gives the input/return impedance as 1MΩ and the output L/R impedance as 100 Ω balanced, with 111 dB dynamic range from input to output, 48 kHz / 32-bit sampling and a minimum system latency of 2 ms¹. The pedal runs on 9V DC center negative and draws under 500 mA¹. USB-C handles 24-bit / 48 kHz USB audio, USB MIDI for the PC editor and firmware updates, and the optional NBT-1 Bluetooth module for app control; an external expression pedal or NMP-2 Lite footswitch connects for expression control¹.

The product page also carries a separate listing for firmware V2.0.5, which it describes as discontinuing the original Monarch editor software in favor of the NUX Audio app, current version V1.1.7.1¹. The page does not give a release date for V2.0.5, and no price is listed for the pedal on the page.
