This is a massive, muff-type fuzz. Every time I play it, I think, 'Should I start a doom band?' Huge low end, even has major bass-boost potential. Remember, this is NOT a typical Tone Bender circuit. It is based on the Big Muff Pi circuit. This is based on the Jumbo Tone Bender, closely related to the Colorsound Supa Tone Bender and Colorsound Bass Fuzz. Has a bit of light scratching on the face and Velcro on the back, but is in otherwise excellent condition. This one is serial number 2, and Matt is no longer making these! Comes with original box. Price is $115 SOLD!!, including shipping, PayPal, etc. Feel free to PM with any questions. Not looking for trades at this time.
