Great amp. I've had mine for a couple of years and have not found a bad sound yet. The multi-watt switch makes it resemble a Champ<Princeton<Deluxe<Pro<Bandmaster at 2<10<20<30<40 watts respectively. You can also plug the speaker into one of the 4ohm jacks at 2, 10, or 20 watts to change the characteristics.
My tubes are all a bit micro phonic but only slightly noticeable.
I did have to take it in for service. One of the caps associated with one 12AX7 (V6) was going out. Everything is all better now. This amp has a 5 year warranty and luckily I live near Petaluma CA.
