Once upon a trim, not so long ago, I had one fuzz which I'd actually built at home. I told myself I didn't need any more fuzzes but that turned out not to be true. This is my 10th and has definitely not disappointed. I'm using it on guitar, not bass (yet) and it fuzzes like the best of them. 4 Switches give even more versatility to the sounds you can get out of it. I'd say just get one. Do it.
