I'm getting ready for a gig where I'm going to have to throw my Crate PowerBlock in a gig bag and run my Ethos speaker sim out into it. The clean sound is world class in this setup, particularly with the clean gain dimed. Problem is, I CANNOT get the dirty channel to keep up with the clean channel if I crank the clean. So I've been experimenting w/ OD pedals in front of the clean channel. Used a Crowther Hotcake, Stephenson Fix-My-Duck, and a Voodoo Labs Sparkle Drive in front last night (just playing by myself, no band last night). Hotcake was very good. Stephenson gave a very lively light overdrive and was butt-kicking when combined with the Hotcake. Didn't love the Sparkle Drive with it, except as a solo boost. So anybody else trying to drive the clean side of the Ethos? Let me hear you.
