On September 24, 2026, Delicious Audio reported on the NUX Mod Core Deluxe MkII, describing it as an update that adds a different set of algorithms and a few useful features to an already solid and affordable stereo multi-modulation pedal concept¹.

The pedal has 8 modulation types, switched by a Type rotary switch: ST.CH (Stereo Chorus), CE-1, SCF CHO, SCF FLG, SCF P.M., U-VIBE CHO, U-VIBE VIB and PH-100²¹. Delicious Audio reports the algorithms are inspired by classic pedals including the BOSS CE-1, the Dunlop Uni-Vibe, the TC Electronic Stereo Chorus Flanger and the MXR Stereo Chorus and Phaser 100, with some represented twice, such as the TC Flanger/Chorus and the Uni-Vibe vibrato and chorus modes¹. The report notes that the previous version's Tremolo, Rotary and Pan algorithms are not in the MkII¹.

Global Rate and Depth knobs are joined by a Tweak control that manipulates a different parameter for each effect, and the on/off switch has a new smart Tap Tempo function, according to Delicious Audio¹. The two stereo ins and outs can run as a regular stereo pedal, or Out 2 can serve as an FX loop in parallel mode (center position), giving two mono outs, one wet and one clean, with the Tweak knob setting the ratio between the modulated signal and the Send/Return signal¹. RockBoard's PedalPedia lists the circuit as digital, running on 9V DC, center negative, at 120mA².

No US list price or ship date is given in either listing²¹.
