Just a really great low volume amp. Being able to have a great tube tone at a low volume is ground breaking for working things out. I have plenty of really loud great sounding amps and now I have a really great sounding low to mid level volume amp. I couldn't be more happy with this amp. Having the ability to go from half a watt to 5 watts is a really amaizing feature for playing when you are not playing out or with a band. I hope to record with is soon and often.
