Killer sounding fuzz. Very early serial number, was updated by the builder, who sadly is no longer with us, to textone specs(added tone knob) which makes it much more versatile and useable with a wider variety of guitars and amps. it can get fat, chewy, and smooth or add treble for dark guitars to brighten them up and help them cut through the mix. Either way this baby takes your notes and spews them out dirtier and grittier than any fuzzface could. Fuzzface on steroids would be a good description. As you can see from the pictures, the previous owner(guitarist for Megadeth, but have no documentation so not even worth mentioning)made a mess of the underside with some not very neatly applied nor removed Velcro. But I can assure you it doesn’t affect the sound ;) comes with original box. Get your Billy Gibbons on with this incredible sounding fuzz that has been long discontinued and become a rare collectors item.
