### 5/5 — Best app

*2026-06-16*

This is the app which makes the guitar sound heavenly. It connects to all my electric guitars(23) without any lag. Keep updating the app for more smooth performance.

### 2/5 — No funciona

*2026-02-04, version 1.9.16*

Hasta hace un par de semanas la app funcionaba de maravilla. Ya no funciona. Se cierra sola. Espero que lo puedan solucionar cuanto antes.

### 5/5 — Hardware

*2026-01-09*

I have an iPhone 15 I want to use this on. What Type - C hardware should I be using to record direct to my interface?

### 1/5 — Locked out it feels like when I paid cash

*2025-10-23*

I paid lots of money for the software many years ago and it won’t let me sign in on my computer. It’s like blocking me so you might end up paying for this software and it might become obsolete and they’ll abandon it and stuff so because of that I wouldn’t buy anything new from this company.

### 5/5 — Doğan

*2025-08-15, version 1.9.16*

Klarnet için tonlarda yardımcı olur musunuz riça etsem

### 1/5 — Rip off

*2025-02-02, version 1.9.16*

I was ripped off by this company.  I purchased add on to the app.  When I switched to a new iPhone.  They deleted my account.   No class.   Jerks !

### 5/5 — Compré todo el paquete de 80 pedales pero no me deja ingresar con facebook,

*2024-10-04, version 1.9.16*

Agradecería la ayuda para ingresar y disfrutar de la compra

### 1/5 — Pésimo soporte de aplicación

*2024-03-27, version 1.9.16*

Soy usuario de bias fx1 funcionó bien hasta que salió biasfx2…
No funciona nada ahí…. Diría que tengan cuidado cuando compren esta aplicación.. es muy buena pero se han desentendido de mi como cliente… aun cuando compre su versión mas cara en su momento…. Esto no es bueno.

### 3/5 — Descepcionante.

*2024-03-02, version 1.9.16*

Mucha latencia y pobre calidad de sonido. También tengo la versión de escritorio y fue una pérdida de tiempo y dinero.

### 1/5 — Complete rubbish

*2023-12-14*

Downloaded the basic pack to get a feel for up to date amp sims on pad and phone. Zero option to audition anything, permanent massive dither on sound like a vibrato pedal and massive switching noise ringing throughout.  If you think this is how to get people to upgrade to anything, you’re crazy! Deleted app, going elsewhere fast.
