I love this little amp but it seems to have more than its share of bugs. The EQX and Drive Switches between channel 1 and channel 3 appear to be reversed. That is, channel 1's switches control channel 3's sound and vice versa. I documented this at this point in a video I made on the amp but thought it might be worth mentioning here. Not the easiest thing to hear since I talk over it but you can hear it or easily reproduce it yourself.
Back in April I posted about how the 7W is louder than the 22W setting which is louder than the 50W setting, but never got any response.
