some good options there, for me i dont mind paying a bit more ive got about 20 fuzz pedals tho, including for me the kings which are the Fuzzrocious 420 V2 and y Colorsound Bass Fuzz
the SF300 is a great clone of the Boss fz2 so no wonder it sounds pretty good, i do now just wanna get a FZ2 and 5 to compare
