Hey Russell ...
I just played with one of these C9's this afternoon ... whatta a blast! I couldn't stop grinning the whole time, at just how authentic this gadget sounds.
I had a guitar identical to my Epi Les Paul plugged into a Traynor YCS90 amp (90-watt, 2x12", all tube) quite similar to my Peavey (100-watt, 2x12", all tube). Everything I did with the C9 sounded better than I could hope for, and since there were no other customers in the shop, they let me crank it up. On the "Blimp" setting with the "Click" knob almost fully off, it got that cool sound for "Child in Time" which is perfect for guitar (G-G-A bass run, then improv, followed by the F-F-G bass run, more improv).
In short, I've got G.A.S. for a C9 as bad as I've ever had for a guitar ... pennies being saved!
