The Ultimate Overdrive

I love this thing. A great base tone to build upon. I like it with a very low amount of gain, just to crisp up the harder pick strokes. The Little Green Wonder is a very dynamic overdrive so it really follows the way you attack your guitar well. Roll the Body knob clockwise from 12 o'clock to boost your high end or alternatively roll it back to get some low-mids in your tone!

Amazing (improved) tube screamer clone

Great sounding tube screamer overdrive pedal. Very dynamic, lot's of gain, can go very clean. Very touch sensitive, cleans up very well when guitar volume is turned down.
