About This Listing

OK, this one has a story. This has some special mod from the factory denoted by the red in the O and E in the logo. I don't remember what the mod is. I realize that doesn't help you, but it is what it is.

SFX-02 Tweak Fuzz

The Seymour Duncan Tweak Fuzz™ is a most unique fuzz pedal that incorporates a six position “Tweak” switch to voice your fuzz tone the way you want it. The basic tone will be familiar to players who remember the rich, lush, vintage fuzz tones used at the big ‘60s pop festivals. But with the addition of the Tweak switch, you can create a myriad of totally unique fuzz tones making this one of the most versatile pedals for electric guitar and bass.


  • Tweak Control: Engages one of six pre-set EQ resonances that give an overall “flavor” to the Tweak Fuzz, rolling off the bottom end and influencing the behavior of the Gain control. Each of the six frequencies was chosen and voiced to enhance rich harmonics and bring out the most flattering qualities of your guitar or bass.
  • Gain Control: Controls the amount of square wave clipping distortion. It can go from mildly distorted to all-out fuzz fury.
  • Volume Control: Sets the overall volume to the optimum level. Whether you want to set it to match the bypassed signal or whether you want a big boost when you engage your Tweak Fuzz: it’s your decision.
  • True Bypass: Removes the circuit from your guitar’s signal chain, allowing your guitar’s signal pass through the Tweak Fuzz without affecting your tone or gain.
  • Power Source: Standard 9-volt battery or regulated 9V DC power supply.
  • Versatile: The Tweak feature allows you to voice the box to your tone preference. Works with guitar or bass. It works especially well with non-master volume amps.
  • Durable: Heavy-duty 1.6 mm steel sheet metal means this unit is built to be stomped.


  • Current consumption: 2 milliamps
  • Gain range: 23dB to +50dB
  • Dimensions: 4.62” wide x 5.10” deep x 2.2” tall
  • Type of circuitry: Discrete, Class A, low-noise transistor
  • Power: DC 9 V battery, or regulated 9-12 V DC adapter
