Diaz Texas Square Face fuzz

     This pedal is basically a version of the pedal César Diaz built for Stevie Ray Vaughn when SRV's fuzz faces kept dying.   It is a Gemanium based pedal and uses NTE103's.   It's housed in a smaller MXR style enclosure and has knobs for volume and gain.
      At it's lowest settings the pedal offers a fuzzy overdrive that increases in sustain and harmonics  as you turn the gain up, all the way up to a massive high gain fuzz with a rich, warm, big sound, tons of sustain, and alot of complexity.   The overdrive tones on the way up are warm and round, with a huge low end and a super sweet treble.   Until you pretty much have the gain all the way up it doesn't sizzle like a normal distortion or even a Big Muff, it's mellower than that.   Totally authentic vintage style fuzz.   I found that setting the gain knob high almost all the way up and using my guitar's volume knob to control the gain was the best way to use the pedal, and it's quite remarkable the wide variety of tones that can be coaxed from the pedal just using the volume knob on your guitar.   There's more to this pedal than you would think with only two knobs.   And the volume knob has enough range on it to crank it up to push you amp harder and get even hotter sounds.
     This pedal also comes with silicon NTE123 transistors that can be swapped for the Germanium transistors or if you want you can combine the two types for even more sounds.   I've never tried this, but this is an added option to an already versatile pedal.   This pedal is about $225.00 new, a little on the pricey side, but to many guitarists it would be totally worth it.
