It is a 5 watt practice amp but the effects and quality are mind blowing. You cannot tell it's a small practice amp you're listening to unless you actually see it. I personally use it while playing live at times giving line out. Has all types of effects from wah to general reverb.
I bought this on a lark in a package deal with my strat. I thought it would be a novelty but I have used it a lot more than I thought. Especially when I finally understood just how cool it was to have an amp than can run on batteries! The amp has 3 power settings: 5W, 1W, and .5W. And surprisingly, even the .5W settings gets plenty loud! After 6 months, I am still on my first set of "C" batteries. Just as mind-blowing is just how good the effects are on this little box. The reverb is luscious, the flanger is flang-tastic, and a ton of other usable effects. Also loaded with over 11 different amp "voicings" (clean, crunch, blues, etc.), there is a just a huge palette of tones and sounds on tap in this tiny box. Buying a DA5 was definitely a happy accident.
