Seymour Duncan

Roll-your-own fuzz tone.

The Seymour Duncan Tweak Fuzz is a unique fuzz effects pedal that incorporates a 6-position Tweak knob letting you voice your fuzz tone the way you want it. The basic tone is a rich, lush, vintage fuzz tone, but by selecting any of the preset tone circuits and playing with the Gain knob you can create myriad unique fuzz tones. The Seymour Duncan footpedal has Volume, Gain, and Tweak controls. True bypass runs on 9V battery or 9V DC power supply.

The Tweak control engages one of 6 preset EQ resonances that color the overall tone of the Tweak Fuzz, rolling off the bottom end and influencing the behavior of the Gain control. Each of the 6 frequencies was chosen and voiced to enhance rich harmonics and bring out the most flattering qualities of your guitar or bass. The Gain knob controls the amount of square wave clipping distortion, making your tone go from mildly distorted to all-out fuzz fury. The Volume control sets the overall level. True bypass circuitry completely removes the effect pedal from your guitar's signal chain, allowing your guitar's signal to pass through the Tweak Fuzz without affecting your tone or gain. Durable, heavy-duty 1.6mm steel sheet metal construction.

Comments about Seymour Duncan SFX-02 Tweak Fuzz Pedal:

This pedal is one excellant deal. It provides the most range, and best tones out of any fuzz boxes I have played. It can go from everywhere from thin twangy sounds, to full, thick, and juicy fuzz balls. It is built like a tank.
