HIT THE SWITCH
AND GET YOUR
PURPLE HAZE ON!
This pedal doesn't need any knobs to send your signal
into over-the-top fuzz and octave up tones. Although this
no-knob fuzz doesn't have any controls on the pedal, it's
easy to coax different effects out of it. The pedal is very
responsive to different pickups. Humbuckers will produce a
more saturated fuzz than single-coil pickups will.

COMPONENTS Resistors and capacitors may also be referred to with CAPACITORS shorthand notation on the printed circuit board The two main uses of capacitors are to store when there is a decimal in the value.
- Page 7 UNDERSTANDING ELECTRONIC COMPONENTS LEDs LED stands for Light Emitting Diode, and functionally LEDs are very similar to regular diodes. LEDs are most often used as indicator lights in pedals. They are polarized just like diodes and electrolytic capacitors and must be installed in the correct orientation to work.
- Page 8 It’s time to install your parts! Before soldering the diodes to your printed circuit board, make sure you thread the leads through the correct side. The side of the printed circuit board that has white values and outlines of the components is the correct side.

- Page 12 Like some of the caps and diodes, the LED is polarized and has to be installed in a specific direction. The negative lead of the diode has a flat INSTALL edge and is shorter than the positive. INDICATOR LIGHT The LED mounting bezel consists of two main parts: A ring that the LED fits into and a plastic plug that goes over the LED from the back side to keep it in place.
- Page 13 Insert the DC power jack into the center hole in the top of the enclosure making sure the longer of the two lugs is on the left. Use a 14mm wrench on the included nut to secure the jack into the enclosure. INSTALL THE DC Solder the inside left wire to the longer lug of the DC jack.
- Page 14 Insert the output jack into the right side hole in the top of the enclosure with the tip connection facing up, as shown in the diagram. Add the washer and thread the nut onto the shaft enough so that the jack can rotate freely. You may need to rotate the INSTALL jack to provide easier access to setting the solder joints.
- Page 15 Similarly, placing a boost or distortion pedal in front of the Interval Fuzz will yield some amazingly dense and sputtering fuzz tones. If you’re looking for a more subtle effect, try rolling the volume knob back on your guitar. Experiment with putting this pedal in different parts of your signal chain to find where it works best for you.
