This is my second Sig X as I stupidly sold my first one years ago. So I picked this one up in 2014 and have been using it ever since.
It's a three channel amp, but they all have built in boosts. I didn't demonstrate the boost on the clean channel because I never use it, and I don't like it. It's too loud and doesn't result in a nicer tone.
Each channel has a mode selector as well as a gain amount selector. These can pretty much be set to taste and never touched. The amp also has a single switchable effects loop, which you can assign to a particular channel, so if you only need reverb on your clean channel you can set that up easily.
I recorded all of 'Exegesis' and 'Wires/Dream\Wires' with a Sig X. Very versatile amp!
