I have a Acoustic Image Contra series II combo I bought in 2003. I have to say I am very unhappy with the over all tone, and always have been. I have a David Eden Travler that I use with the AI speaker, it has much better tone and presence, but I have been having problems with it latley, so I have been forced to use the Contra amp. The contra has a thin nasely tone, I ask myself was it worth the expensive price tag. The musicans I play agree, the Eden is way better. I have talked to a few players that echo my opinion, but everybody here on TB seems to love Acoustic Image. ???
