Just bought myself one of these. It's still in the box (I'm at work) so I'll have to follow up with a later report on what it does. http://www.guitarcenter.com/Line-6-Micro-Spider-6W-1x6-5-Guitar-Combo-Amp-104835905-i1390847.gc
No, you have to read it. Moving on..... So far, the sounds are cool if somewhat limited. I haven't been able to crank it up to see how loud it gets but that should happen this weekend. You can change the tempo of the echo by tapping a button in whatever tempo you want. It assumes that tempo and, off you go. So, rather than turning a knob or setting a number, it relies on my white-boy rhythm to grab the beat. It has a mic input with its own trim knob so you can sing along through the amp. You could also add another guitar but it would be clean only. Or, add in a drum machine (which I'll do). It also has an MP3/CD input so you can jam with your itunes. And input footswitch would really set it off so you could change channels on the fly but, for it's size and cost, it's pretty neat. And it runs on 6 "C" batteries for jamming out after a nasty hurricane knocks out your power.
