Fuzzhugger Algal Bloom V2

From the Source 

The Algal Bloom is a harmonically rich, wide-range fuzz! From mellow to gritty overdrivey tones, to beautifully thick fuzz, to crunch, crust, and throaty fuzz roars! V2 adds an all-new Choke toggle that turns the Algal Bloom into a Harmful Algal Bloom, a raunchier mode that goes from dying to crusty, to crunchy, to whiplash! A new 3-way filter toggle lets you smooth clipping and highs for ultimate control.The Algal Bloom is known for its open tone and many chord-friendly settings, with fantastic definition and note-separation, even on high gain settings. The controls are uniquely interactive for incredible range. The pedal has a unique sound and circuit, but also expands on some classic tones that fuzz enthusiasts will love. A workhorse of a classicish, garagey, all-around capital F Fuzz. 

The Controls! 

Gain: Gain adjustment and clean-up! As you back it off, it cleans up your fuzz, also adding a hint of sputter and fizzle. Hard right is full-on!

Bloom (Fuzz): Expands and pushes your fuzz tone, adding gain, sustain, and definition. Hard right is maxed out...a unique, throaty, brash-yet-full tone! 12 o'clock is its "home setting," for thick fuzz tone!

Power: Controls the flow of power to the circuit, altering response, heft, and gain (slight scratch is normal, as circuit adjusts to voltage change)

.Level: Your master volume control.

• Choke / HAB Toggle: the V2's new Choke toggle, letting you dial in whiplash, crunch, crud, crust, dying, and dead. 

• Filter (3-way):
1) Middle: the unfiltered Algal Bloom you know.
2) Up: slightly smoothed highs, reducing clipping and fizz activity from the highs.
3) Down: smoothed and dampened.



  1. Took a crack at building this tonight. I've got no signal at the base of Q4, however I have signal at Volume 2 and Clean 2, which makes no sense to me. I'll double check it with a fresh pair of eyes tomorrow.

    1. i think i spotted the error. one of the cuts was misplaced. there should be a cut at column j row k, and there shouldn't be a cut at column i row i. so you can make the corrections by making the new cut and put a jumper (small piece of wire) on the copper side to essentially remove the wrong cut.

    2. Looking at the schematic from Wecallthepolice at FSB, It looks like there should be two 2.2M to the ground of Q1. One to ground, and one to the drain. I'm going to jump the cut at k,f and add a 2.2M to ground from that row. It looks like it will fit at k,k to n,k

    3. A couple more discrepancies I found compared to the schematic I mentioned above. The 470pf two ground should be on the other side of the 1k resistor, and the 100n capacitor connected to the voice 3 should be 10n. I won't be home to make these changes until later tonight, but I'll report in when I do.

    4. thanks for spotting those. i originally only looked for issues around Q4. i went back over the whole layout and schematic and found a few other issues. i corrected the layout accordingly.

  2. Tag it my friend.

    Very clear sounding fuzz, even with the bloom turned up. It gets pretty nutty with the choke and the the power knob. I like it a lot. Thanks for the layout!

    1. great. thanks for working through it to get the layout right, and verifying it so quickly. cheers
