Crikey... See I'm not sure whether to go full-on JCM or get the option you describe. If that actually got the Slash tone then it sounds like it covers clean, crunch and proper distortion. Else I'd go for full-on Slash JCM.
Daaaamn.... if it can get the Slash-type tones when boost is kicked in... I don't see the point in having a JCM option at all as you have it ALL there ! Did you ever do any demo vids / clips?
Look forward to it
