Independent shopping perspective
Amp Academy Stomp puts NUX amp modeling, cabinet IR management, routing, effects, and a stereo looper into a compact digital pedal. Its TSAC-4K engine treats preamp and power-amp stages separately, and the Cyber IR section offers 60 factory choices plus 40 user locations. Nine effect blocks can run in serial, parallel, or branch routing. For a direct rig, it provides stereo outputs, USB-C audio-interface operation, headphone output, MIDI I/O, and scene or stomp control.
