## What is JMP Pro?

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.

### 5/5 — JMP-1 Goodness!!!

*2022-08-23*

Been waiting years for a JMP1 and here we are. I’m a little over 3 weeks into this and it is absolutely awesome and amazing. I have been a JMP-1 player for well over 10 years and now I have the opportunity to use it on my IPad with cubasis and auria pro. It really does sound good and the possibilities seem endless with the addition of delay reverb power amp and noise gate. OD-1 is where it’s at for me……thanks and well done Nembrini!!!! This is one of the very best I have ever tried that simulates the JMP1.  Go buy it now!!!
