I was frustrated with my Blues Junior. Not a bad amp, just a bit boxy, too much mids, not the sound I wanted. But I didn't want a 10" speaker from the "standard" Princeton. Also, I was also looking for an amp that took overdrive/distortion/hi-gain well.
And this is it. I've had it for 2 weeks now and it's both the glassy sound I was after AND the pedal platform I was looking. I go effortlessly from a John Mayer type sound to RHCP, Hendrix, Led Zeppelin using standard pedals (DS2, RAT, TS, Klon).
The 12 inch speaker makes a huge difference from my point of view. The bass response is balanced and it suits very well other types of style like Jazz.
I even made a video on youtube if you want to check it out. Title is : Fender FSR British Green 12 inch Princeton Reverb G12-65 Limited Edition (Channel: Vivien) mentioning that the actual is not as green as in the picture. It's clearly misleading. It's a dark green, like a 'navy blue' but in green.
