I have the Pro Junior. It's a great amp.
If you get one, change the stock tubes right away. They're cheap Sovteks, and they sound harsh and buzz like crazy. I put in some JJ's and the tone has improved greatly, and the hum was brought under control. The stock speaker isn't bad, but a lot of people change it to something better. I haven't done this yet to mine.
The overdrive is controlled with the amp's volume, so if you want to use it for clean tones, you'll have to keep the volume fairly low, and you might need to mic it to use with a drummer that way.
Cranked, the amp has an incredible overdrive, and can easily compete with a drummer without being mic'd.
