1-Knob Fuzz Bonanza

Request. This is just to add the requested Black Arts Toneworks Ritual Fuzz to the library, but i just couldn't resist rewriting Dr. Tony Balls' "Universal One-Knob Silicon Fuzz Layout" and adding the Black Arts' version of this classic to it. So here are 5 currently known adaptations of the almighty 1-Knobber. Adventurous minds could swap the values and get theit own flavour in there.. Simple and small. I sense small box fuzzes coming... :P

Edit. Oops.  I made a tiny error on the original layout. Lower electrolytic, the Q2 bypass cap, needs to be minus to ground.. Layout fixed. Should work fine, but the cap will probably die a lot sooner if it is in reverse. Now fixed...

Tycobrahe Octavia

Requested by Javi .... haha
I don't think I'm going to find any marketing guff so here is what Wikipedia says about it:

The effect was used by Jimi Hendrix, and can be heard in guitar solos on the song "Purple Haze". Hendrix preferred to call the device the “Octavio”, and it is often referred to as such.

After Hendrix's death in 1970 one of the original Octavias became the basis for the redesigned "Octavia (TM)", manufactured by Tycobrahe Sound Company in Hermosa Beach, California, during the mid-1970s. A limited number of the devices were produced, and today a used one in good condition sells for over $1,000 on eBay. Stevie Ray Vaughan owned nine of these devices.

I can't find a vid either so this is close enough :o)

EarthQuaker Devices Hummingbird

It's a modded Vox Repeat Percussion so more use for those 2N2646's you stocked up on.

Info about the original:

The Hummingbird is, at heart, a hard and choppy tremolo. What comes out is more akin to vintage synth style oscillations. It's core is based on the old Vox Repeat Percussion with several updates to reduce noise, enhance the "chop" and add more control. It can create ring mod-like octaves, slow pulses, ping pong delay-like stutters, light blipping through machine gun stutter tremolo and many more wacky sounds!

Controls:
Depth- Controls amount of modulation from barely there to full signal chop.
Rate- Controls the speed of the LFO
Level- controls the input/output level
Mode- fast/slow switch for LFO rate

Fuzzhugger Phantom Octave

 I do find these small boards less stressful to draw :) This one is small enough to fit in 1590A without any problems, but if you're feeling adventurous you can shave off one row from the right hand side. I left there a bit space so 100µ caps have more room to sit in nicely... Schematic has the onboard LED as 5mm red, but you could try out different colours to see how those affect the octaves.. I must add that this puppy is sounding pretty cool and it is priced reasonably, so you should consider getting yourself an original...

From Fuzzhugger(fx):
Equal parts mysterious and ghastly, the Phantom Octave is a shape-shifting octave fuzz monster!

No controls? They're not necessary--they're at your fingertips! The Phantom Octave is extremely interactive with your pickup selection, picking intensity, and your guitar's Tone control. Like its namesake, the octave will disappear with picking intensity and by rolling back your guitar's Tone control. Octave effect is strongest with low-output single coil pickups.

With the flip of your pickup selector and your picking technique, you'll find huge octave downs, glitchy ring mod-ish tones, and even be able to bang out some simple chords! Set the intensity of the effect by using your guitar's Tone control as a Blend. Roll your guitar's Tone control all the way back, and you've got a chord-friendly fuzz!

The Phantom Octave is a very strange pedal compared to most octave fuzzes...in some ways, it's more stable...in many ways, glitchier. It'll sound different with each set (and combination) of pickups. Some pickup selections will produce more exciting results than others. On most guitars, the Tone knob allows you to blend out the intensity of the octave and glitch. Easier to master and jam on (which is not to call this beast stable, but)--for example, you'll be able to get away with some bends and power chords! You'll quickly get used to the sensitivity of the pedal and what different playing techniques and settings will
produce.

Controls:
• Output: Controls the output level of the Phantom Octave!
• Interacts strongly with your pickup selection (and playing technique). A guitar with a three-way selector means three settings!
• Your Guitar's Tone knob will blend out effect intensity. When blended out, you get a nice smooth fuzz tone!

• Must be used with passive magnetic pickups (standard guitar and bass pickups), and be placed first/early in your effects chain.

Here's demo of Geiri's build:

Top Gear Fuzz = Guild Grizzly

Couple of small circuits to keep you occupied on this sunday.. :)

This one's yet another Fuzz Face, but both boxes using the circuit are quite cool things..
