I own every Amp Sim. This is the most versatile Amp Sim for my money.

Nembrini won me over with the free Crunck V2. It’s really in your face but Breo bones. I then scooped up all the FX stompers. And one by one each new Amp Sim had unique tones I liked. This one topped them all for my tastes. It’s got a cab emulator, Reverb, Rectifier emulation and the best Clean Sounds I own on IOS and I own them all. There are more coming but the prices are fair and owning them all is a solid investment in the history of guitar tone shaping. The Pre-Amp and Delay are also best I I class for their category.

How long have guitar players been waiting for good AUV3 amp sims? Finally! This sounds really fantastic with high gain riffing and chords but also beautiful clean rhythm playing. I have hundreds of really good cab sims I was set to use with this but I like the included cab/mic/speaker selections so much that I don’t bother. If you are a guitar player you should be supporting this developer. When was the last time you paid $10 or $20 for a pedal that sounded good? Probably never. The Nembrini apps are a steal!

I just discovered Nembrini Audio about a week ago. It was love at first chord. The dynamics on your ears and fingers are as good as it gets. This amp is no exception. Totally awesome. I have used many, many iOS modeling amps in the past. Trust me, Nembrini is in a class of it’s own! Get this now!! 🤘🏻🤘🏻
