Wow! The CA9 did a great job last weekend. I used my Roscoe 6-string on Friday's gig and my P-Bass on Saturday's gig. I used only one side of the amp. I never had to run it's gain past 1/2, and I was plenty loud. It gave me lots of clean volume without clipping/distortion. I can't wait until I can afford a cabinet that does my Roscoe's B-string justice. I even noticed my Ampeg BXT410HL cab was moving a lot more air than with my previous amp. - I love when an amp makes my pantlegs flap! Yes, the CA9 weighs quite a bit more than my previous amp, but that's why I own a hand truck. Phase one -Read Purity preamp Phase two -Crest CA9 Phase three coming at tax refund time!
