11 knobs of fuzz that is definitely not related to the ZVEX Fuzz Factory at all. Fuzz Factory and ZVEX are trademarks of ZVEX. However, Adjustable Suck Fuzz is here. You can buy it. You can build it. I designed it for the fuzz hungry dog in you. Make a loud statement with this outstanding FUZZ. Tell the world that you don't care anymore, you just want to blow the speakers off your pawn shop cab. Perhaps you are the discerning connoisseur of FUZZ looking to add something tweakable to your curated collection? The front end impedance control allows you to go between synthesizers and guitars or to mismatch the impedance intentionally for volume dropping tone sucking sound sculpting. That is just the beginning. there are 3 tone knobs in total and a built in diode distortion than can be switched off or dialed in. There is a bass control (for electric bass guitar) that completely changes the guitar only voicing. You must spend some time playing with this thing to be truly happy.
