Blended from circuit-archetype lineage, dynamic feel, tone-signal overlap and tone-vector distance — the tone vector itself is derived from editorial description text, not a measured acoustic signal, so this reflects how similarly the catalog copy describes the two, not a lab measurement.

The NUX Optima Air NAI-5 is an IR-based acoustic guitar simulator and preamp stompbox that converts electric guitar signals into acoustic tones. It features 15 built-in acoustic body IR profiles with external IR loading capability, a Neve 1073-modeled preamp section, three-band EQ, reverb, XLR DI output, standard output, and headphone jack with an OLED display. Designed for live performers and studio players who want acoustic tones from an electric guitar, it excels in fingerstyle, folk, country, and singer-songwriter contexts. Third-party IR compatibility significantly extends the tonal range beyond the built-in voicings.
The Mad Professor Royal Blue Overdrive covers a wide range from light overdrive into full distortion, with Volume, Distortion, Treble, and Bass controls. At its lowest Distortion setting the pedal behaves almost like an EQ stage, adding minimal filtering for a transparent boost. Turning the Distortion knob up moves it into a crunchy, tube-amp-like breakup and eventually into heavier gain. Both Treble and Bass are boost/cut shelving controls, giving broad tonal shaping rather than a single fixed voicing. It is built to go from subtle amp-like grit to genuine distortion within one pedal, and forms the basis of Mad Professor's Supreme A-side circuit.
