BJFE / Bearfoot Pink Purple Fuzz

To keep the collection complete this is the second recently reversed BJFE/Bearfoot pedal, drawn up by mmolteratx, thanks again Matt.  Again this one sounds great to me.

Info about the original:

The Bearfoot FX Pink Purple Fuzz blurs the lines. Is it pink or purple? Is it fuzz, overdrive, or distortion? In terms of the color—can’t it be both? In terms of the tone? It’s all three, depending on how you dial it in. The Pink Purple is very high gain, while remaining very low-noise, housing all your daily fuzztones (no crazy octaves or gated fuzz here) and blurring the lines between fuzz, distortion, and overdrive—with a versatile mid-EQ knob that takes you through a range of useful fuzztones.

Bearfoot FX is the brainchild of Bjorn Juhl of BJF Design and Donner Rusk of Donnerbox. Every pedal is handpainted and no two are exactly alike. The pedals now ship with a plain, unpainted bottom plate to help ensure the most secure contact with adhesive Velcro for use on pedalboards. Bearfoot FX pedals are handmade in St. Louis, Missouri, USA.

Ibanez OD855 Overdrive II

Now. This is per the factory schematic, so it should (finally) be ok - don't go looking for the old defunct layout, as it is gone for good. Transistors are used for buffers, so i swapped the pinouts for your everyday devices. Tone pot is G-tapered 20K in the original, but linear should work fine in its place. Turned out pretty neat and still quite compact.

Thanks to Norwichbadger - this one is now verified.

Ibanez Overdrive II / Dirt Box


This layout is for the original Overdrive II, not OD-855. The same circuit has been sold as "The Dirt Box" too. More interesting details of the design at Tonemachines blog.

BJFE / Bearfoot Arctic White Fuzz

Back from holiday and thought I'd do a new layout to try to cheer myself up after feeling the difference in temperature :o)

The BJFE/Bearfoot Arctic White Fuzz is YAFF but certainly has been souped up and sounds great to me.  I'm sure it will be as popular as Bjorn's other effects.  Thanks to Matt for the schematic.

Info about the original:

Another favorite from the BJFe research program .... The Arctic White fuzz purrrs like a snow leopard at lower levels and attacks with full vintage growl when pushed ...... this is the most straight forward of the BearFoot fuzzes .... vintage in sound and feel with its own voice and personality.... and its a great recording fuzz as Bjorn wiped out the backround noise found in most fuzzes... 8-18v ... Volume Level - Fuzz Level and Tone control with just the right amount of treble control to match the Arctic to your little piece of the tundra .....and your Honey Bees new best friend.

Morley MOD-D1B Distortion One

This one seems to be quite rare thing. You can score one for >$200 at ebay. It is Morley's vision of the MXR Dist+/DOD OD250, with some noticeable changes. Might be worth a build...

Boss OD-3 SubClone

Found this floating around the interweb some time ago. It is OD-3, with tone control, buffering and switching components removed. The original design would be crazy big and undoable (at least for me) on vero. So this WGTP's simplification of schematic supplied by J. Luja more than 10 years ago should suffice. According to DIYSB thread, it should sound very close to the original. Like the name suggests, it's not a clone, but a SubClone. Offering what makes up the OD-3 sound but in a lot smaller circuit footprint.

Here's a Boss Soundcheck clip of the original:

BMP Tonestack w/ LPB1

I've noticed a recurring request on how to add tone control to layout x (where x = any layout without tone control). So i thought that i'd draw up a simple addon board for simple Big Muff Pi tone control, so that anyone can take it after any board's output. But as many of the designs (older ones in particular), have quite low output, adding BMP tonestack would do a number on the maximum level. Probably even render some moderate/low output circuits unusable. So i just added your average LPB1 booster after the tone control to act as make up gain stage. You could easily swap the trimmer for "master volume" control if you wanted to - which could be a sligth overkill in many situations.

So. Take your fuzz/od, take the output from there to this circuit's input and use the output from this as your new output. Simple but effective tone control for any design.

Needless to say, this may not be too great project by itself with missing input cap and some other small details that really want a circuit before it.
