First off, if UPS doesn't screw me over again, I have a Focusrite ISA preamp on the UPS truck for delivery today. Once I get it, I'll do a profile with the Focusrite, one with an ART tube preamp, and one without any preamp. Obviously won't change anything else - just the preamps or lack thereof.
Should be interesting to see what difference (if any) they make.
Also have made a deal but haven't paid for/picked up... a Mesa Maverick! 35 watts, EL84, not a crazy high gain head, more of a classic rock head. Two channels, probably does some voxy things pretty well. Looking forward to having some profiles of this up and around.
Stay tuned!
Pete
