NUX has released the Solid Studio MKII, a stereo amp and cabinet IR simulator, Guitar Pedal X reported on June 11, 2025. International dealers listed it at $199 and equivalent1.
The pedal carries eight amp types, five power amps, 27 factory IRs and 60 independent IR slots per side, along with eight mic types, relative speaker placement, an eight-band EQ, four reverbs, four delays, a noise gate and free routing1. Its 2.86-inch color LCD (960 x 376) sits alongside 128 presets, USB-C MIDI, USB audio, editor software, stereo balanced outputs, phones, AUX and a THROUGH jack1. NUX rates dynamic range at 110dB and latency at 0.85ms bypassed and 1.9ms with effects engaged1. The chassis is one-piece die-cast aluminum, and the pedal runs on 9V DC, negative tip1.
Guitar Pedal X lists the eight amp types as Jazz Clean, Deluxe Rvb, Twin Rvb, UK A30, Brit 59 SL, Brit 1987, Stageman and Bassmate, supplemented by EL84, EL34, 6V6, 6L6 and solid state power amps1. The same report describes the pedal as more of an IR configurator than an amp simulator, and says it sounds darker than the NUX Amp Core Studio1.
Delicious Audio, in a piece updated January 7, 2026, describes the MKII as adding true stereo IR loading with microphone positioning and distance control, developed with Choptones IRs, and 24-bit/48kHz USB audio with simultaneous dry and wet recording2. It gives the MKII's latency as 0.85ms bypassed and 1.9ms engaged, against about 2.5ms and 3.5ms for the MKI, and the MKI's USB audio as 16-bit/44.1kHz2. Guitar Pedal X gives the sampling rate as 48kHz/32-bit1.
