Sorry to hear this. I sold you the amp. Didn't know you didn't know how to use it!
ca-9100 gives maximum 20db gain.
ca-9200 / ca-ugly II gives max. 40db gain.
I've used ca-9000 , ca-9100 , ca-9200, ca-uglyII and for normal rock shows on all amps I've never used more than 15db gain.
Only time I used 40db gain is for fully acoustic shows.
Oh well. Now you know. Better luck next show!
