The COZMIC FUZZBALL pedal starts with the same circuit as the acclaimed Crunch Transparent Overdrive, though you’d never know it. THE COZMIC FUZZBALL enters our line-up with the addition of a transistor that can be overdriven for that sweet fuzz and a clipping stage that adds distortion even when the pedal isn’t driven to fuzz-land. The COZMIC FUZZBALL is suitable for both guitar and bass.

"MCGREGOR PEDALS First-Ever Fuzz Pedal is Crunchy as Hell.
McGregor Pedals is taking the knowledge they’ve accrued from being in the overdrive pedal game, and using it to make one hell of a fuzz pedal."

Attack: This controls strength of the signal hitting the transistor; more attack = more fuzz and sustain, at the lower end with low output pickups the effect is mild distortion/overdrive. As you bring up the attack the distortion gets stronger. Soon you will hear fuzz starting to layer in. Pin the Attack and you are in fuzz-land. The output of your pickups will have a significant effect on how much fuzz is generated (as will your guitar’s volume pot). Bass Players, start with the Attack near minimum and go from there.
Tone: this is a variable high pass filter; the left side of the range is more for bass guitar, the right for both bass and guitar.
Vol: This attenuates the amplified and clipped signal after it leaves the tone filter.

LED Brightness (Unmarked Trimpot on the side)
As a player who occasionally plays daytime outdoor shows, I wanted a super bright LED; however, this made it horrible to use in any other situation. So, I added trim-pot that allows you to vary the LED brightness from dark stage to bright sun. Please make the adjustment gently using a jeweler’s screwdriver.


  • Type: Fuzz pedal that cleans up to distortion
  • High impedance input (doesn't have to be first in your chain)
  • Hand soldered in Vancouver, Canada
  • High grade components picked for their superior sound and response
  • True bypass
  • Three topside controls – Volume, Tone, Gain
  • LED Brightness controlled by side-mounted variable resistor (trim pot)
  • Low power draw: 12 - 18mA (9v) depending on LED setting
  • Audio Jacks and Power Connection located at the top end to help with packed pedal boards 

Power Adaptor
The McGregor Pedals Crunch Transparent Overdrive may be powered by a 9VDC adaptor. It accepts a standard filtered/regulated pedal power supply with a center-pin negative 2.1mm x 5.5mm plug (like Boss, Ibanez, etc.). If an adaptor doesn’t seem to work, disconnect it immediately and check the polarity. Also, check that it outputs DC (not AC). Current consumption is 10-15mA depending on the LED setting.

For my pedal designs I’ve opted to omit the battery compartment, primarily because batteries are environmentally unsound. Batteries contain acid and heavy metals that end up in landfills, in soil, and in the oceans. All my pedals are built with RoHS compliant parts; batteries don’t make sense.
