I bought it as my main amp for anything(practice, small gigs-medium sized gigs) and it does the job more than well! 
I'm a big fan of the blackface sound and this one crushes all of them. I even sold my Deluxe Reverb amp, because the Princeton just sound better. 
 
Pros: 
-it's small and not so heavy(keep in mind that is a tube amp) 
-the sound it's just the one that comes to mind thinking about a blackface 
-the reverb it's fantastic 
 
Cons: 
-not so good for transporting, as with all tube amps 
 
I play mainly jazz and some blues, and for this style of music it's really the best that you can get! I 'll recommend buying it if you're looking for that blackface clean but on the edge sound with a great sounding reverb. And with a great customer service that Thomann provides, it's worth the try.
