For all the guys looking for one to try out in their area, but can't find one, I'd say if you're interested, just go for it. I bought mine without playing through one previous (I was able to play the 300SB briefly). I'm still blown away with it. If you want that tube sound, this is it. Of every review I've seen, I've yet to read one negative comment regarding the tone. Yeh it's heavier than a micro, and you've got to replace the tubes at some point, but if you can work within the limitations of an all-tube amp, you won't be disappointed if you pick this one!
