Good Price. I've only played the Red. I liked the red, but still needed an overdrive going into it for me. Didn't think it had much gain. So I am guessing the blue wouldn't either. I'd love to see a stupid deal of the Revv G3, cuz I'd probably try that.
I am using a Boss Blues Driver right now into a 73 Silverface Bassman. I don't do the high gain thing either but I think this hitting the front of that Bassman will sound real nice.
The most gain I use is in my 2555x, 2203 or 1987xl. No pedal needed with those, other than TC Elec. Spark boost. My 1959 need some extra gain out front. I don't play anything heavier than VH-like distortion. Chugalug or Cookie Monster stuff is not for me.
