PREAMPLIFIER Nembrini Audio JMP Pro Guitar Amplifier plugin is based on a Marshall JMP1* preamplifier. JMP Pro Valve Amplifier drives pure tone into each of its four uniquely voiced channels OD1, OD2, Clean1 and Clean2 OD1: This channel’s smouldering power will take you from the molten gold of a classic British sound, to searing metal and all points in between. OD2: Tightly focused, high gain is served up here by the truckload. Modern and aggressive, yet fluid and toneful. This channel has all the distortion and sustain you’ll ever need. Clean1: It is perfect for warm full-bodied chords, fat clean lead passages and jazz tones. Clean2: It has the glassy edge of a classic British sound for those bright, jangly tones. POWER AMPLIFIER Powered by four EL34 virtual tubes with presence, volume and power switch in class AB push-pull configuration. DIGITAL DELAY FILTER make the delay Lo-Fi and OFFSET create a time offset in left/right delay sections ANALOG MODULATIONS select Chorus or Tremolo modulation AMBIENT REVERB Hall reverb algorithm FILTERS CLEANER Low and High cut filters PRE and POST amplifier ANALOG NOISE GATE tuned for guitar and bass STUDIO COMPRESSOR keep your dynamics in check, whether just thickening the sound or keeping levels consistent Works as a standalone app, AudioUnit v3 effect, or Inter-App Audio effect.
