Granted she has a cool idea. However, designs like this...
..are just uneducated. Yes it'll work. There are also a LOT of problems with it. It's a hack job to be honest at every level.
If anyone is interested I'll be happy to tell you why.
Yes but if one is going to show circuits like this, expect a response, if for anything, to learn something from it. There are better ways to do it. That isn't one of them. It's a mess from the get go. In fact it's really bad. Fact.
//edit: Again. If anyone would like to know why, I'll tell you.
Very bad design. What she has there, beacuse it's a bass and doesn't deal with chords, is a very bad fuzz box. It's pretty scary. Do not build this . lol. I cannot say that enough!
