### 1/5 — Horrible

*2025-03-16*

Doesn’t work half the time Have to re-plug headphones and I rigs and everything over and over to get it to work then sometimes it just won’t work at all. I owned an MP1 back in 1991 this is just not there. In my opinion I think it’s a little overpriced compared to Aurora’s rhino which works better by the way than the MP1 which is more of an 80s metal style anyways, I don’t know. I’m just not happy with this app at all and every time I give it another chance and try it again. I’m just more disappointed with it like I am today.

### 5/5 — It cool

*2025-01-16*

I bet the full version for iso is incredible this one works to

### 5/5 — OMG, this is the best one by far.

*2023-05-29*

I have been on a buying spree purchasing amp sims ever since Logic Pro was released on iPad.  This AUv3 plug-in sounds absolutely amazing.  So full, so rich, so in your face.  It inspired me to start using my iPad + audio interface as the preamp on my rig.   On desktop I mostly use amp sims by NeuralDSP.  This is as good as their best.   Get this, you won’t be disappointed.

### 5/5 — FANTASTIC!

*2023-02-12*

I believe I purchased all but 3 of Nembrini amp sims.  This one really knocks all the others I own out the park.  Thank you for Creating these gems.  Keep up the good work.  Hoping to see from nembrini soon🤘❤️
