I just love my Orange Tiny Terror. Switched the tubes to make it even better.
This thing can do a some clean, great overdrive for anything blues or rock and can even go up to metal terretory.
Depending on your choice of tubes you can amplify certain of these characteristics nicely.
So far I never had a volume problem, especially after switching the EL84s. First there is laughing from other musicians, then they just tell me to turn it the $% down and compliment me on my tone.
You can also get the dual terror, which has 30/15/7 Watts, were the normal one has only 15/7 Watts, which is enough, believe me.
If you are into british sounds this thing is amazing.
