As said in previous comments, this is not a valve amp but the feeling is very close. I bought it to record guitars, this device makes the process faster, easier and with better results. I live in a flat, so recording valve amps with a mic is not an option (too loud), I have a torpedo but never been 100% satisfied with the results using IRs, even if it was a huge improvement. Now, it is super easy, the Simplifier is on the pedalboard, a xlr cable and ready to record. The sounds I get are great, on both channels. I started by applying the recommended settings (Fender-ish amps) and it worked perfectly immediately, with single coils and p90. The device can look intimidating but is not, these are more or less the regular knobs you find on an amp. I already re-recorded some songs as I was super satisfied with the device and knew it would improve the recordings. I am sure it will be super convenient to play live as well. For my usage, this is the perfect device, very happy with my purchase.
