Ok, So I have a Clarus 1 down in my studio right now, and was doing the A/B thing next to my SM900 (I know...don't say it, I know they are different like apples and oranges) to compare how the tone is. It sounds great but, those of you that do use it, have you ever pushed it hard and how does it hold up?? Not like I play in a thrash metal band, but some gigs I do get kinda loud (funk, R&B, blues). My current set up is a SM900 and a pair of Aguilar GS 112's. Lotsa good clean headroom is not an issue. The 112's may go away for a Epifani 310 UL, still thinking about that.
