It's silver and it's louder

I owned two of the 300s actually and liked the Micro 300 a lot- the new one seems to sound almost the same but a bit warmer (they apparently are using a different power supply and circuitry with this one), but I haven't played the 300 in a long time now so I can't be positive. I sold the old one as they couldn't provide enough power to my power-sucking Acme cab- the new one definitely remedied that.
One of the joys of being a non-gigging hobbyist is that I can sell gear I really like for simple/stupid reasons like wanting to fit an effect unit in my rack
I also forgot to mention that the effects loop level knob sticks a bit- I'm sure it can be easily fixed with WD-40 or something, but I'd need to double-check with EA first to get the best method.
