Curious - what distortion vero is the smallest when it comes to a part count. Not including the off-board wiring. I thought it might be interesting to see what might be out there.
Not only is the Green Giant a very simple build, it also sounds superb. On a parts count to sound quality ratio, it has to be right at the top of the tree.
If you're looking for something more than an overdrive, going into some real distortion are, the higher gain Nick Greer Sucker Punch sounds amazing and is only a few parts more than the Green Giant.
