I'm not sure if i have ever been happier with a piece of software than I have been with S-Gear.
It sounds great no matter what I run through it. Be it a real guitar, software/sampled guitar or a James Tyler Variax.
I literally stopped using Pod Farm, Guitar Rig & Amplitube after purchasing Scuffham Amps. (I do still go back them every now and then for effects that are not included in S-Gear)
I can't wait to hear the new Wayfarer amp!
