2 : Almost perfect

My only gripes are the following:

- No pad. This should be a basic feature on ANY interface, always. My medium output pickups run hot on palm mutes - I am a hard player, but this will 100% clip your signal if you also have medium to high output pickups.

- Worse signal:noise ratio when phantom power is on - this is negligible when you close-mic or mic up a loud source. Nevertheless, it's a circuit design flaw.

- (This is just my preference) The stereo/mono switch should be for the headphone/speaker outputs and not pass-through monitoring.

Everything else is fantastic!!

Honestly, this is a phenomenal interface and I'm incredibly happy. It also looks great, it's very solid and I love that the input/outputs can be plugged in neatly in the back. This is an AWESOME desktop unit, for a really (really!) good price (and comes with SSL plugins).

4k Button

Sidenote, the 4k button is a high shelf. It will increase everything above 1kHz (the shelf curve starts at around 1kHz and reach a plateau from 10kHz up). It's a little aggressive for my taste, but if you have a dull/warm mic or want to brighten your recording, then this will be really handy.

Pro tip: if you have old guitar strings, this shelf might save your recording. New strings are ALWAYS better, but this is a (very naughty) little cheat.
