Just want to say thanks to RunoffGroove

... For their "Little Gem Mark 2" LM386 amp. I built one to use with my "transduce anything" guitar sustainer. It works great for that, plenty of power and low noise. But last night for kicks I tried it plugged into my 4x12. Holy crap! What a cool little practice amp! Really sounds nice. Cool "amp like" breakup and controllable with the guitar volume knob. I thought it needed a little more treble so what to do? I plugged my Rangemaster into it and I couldn't believe the killer sound I was getting out of it. I was even getting some feedback out of it too. Just two tiny little 1590B boxes and a closed back 4x12- amazing... Thanks guys!
