The NU-X Pulse (NSS-4) is a compact mini IR loader pedal with 24 built-in cabinet impulse responses across three modes — electric guitar cabs, bass cabs, and acoustic guitar IRs. Switch between modes using the tap switch. Stereo input and output are supported via 1/4" TRS. A 3.5mm headphone output enables silent practice, and USB connectivity allows direct recording into a DAW as an audio interface.
