I got it today and spent about half an hour with it. It's a keeper. It's got a blend knob to gradually add distortion to your original tone, the gain goes far beyond overdrive into fuzz territory, and the high and low knobs are good at tailoring the distortion. My favorite tone right now is high gain and eq with only a little distortion blended in. I'll know more when I gig it next week. It seems well built, all metal w/ a solid click when you step on it. Battery included. For $20 I'm very happy.
Now everything is clear -- in mind and in tone. I have dewired all of my amps. They now run off of broadcast power from the mothership. ALL YOUR BASS ARE BELONG TO US!!!
