Hudson Electronics Broadcast

Original info:
The Broadcast is a transformer coupled, discrete Class-A germanium pre-amplifier based on the classic broadcast consoles of the 1960s. In the low-gain setting, the Broadcast can cover everything from sparkling clean boost through to transparent overdrive, all with a healthy dose of volume available to push your amp. The Broadcast features a specially selected Triad steel-core transformer and a NOS germanium transistor. Advancing the gain on the Broadcast starts to saturate the transformer and the pedal’s discrete circuitry, giving rise to a gentle and dynamic compression coupled with subtle thickening of the midrange. With the gain switch in the high setting and the trim control wound up, the Broadcast starts to deliver heavier distorted sounds with a warm and fuzzy edge to them. The Broadcast covers a wide range of driven and distorted tones whilst remaining dynamic, responding well to pick attack and the subtle nuances of every player.

Thanks to Tipunk777 for reverse-engineering his own pedal in the Forum section.
There are 2 layouts:
one with a 24V charge pump and one without.
02/11/2016 Layout updated! Gain 1 was connected to wrong spot. If you've built the previous layout, just connect it to row 7, right above Sw1.

Earthquaker Devices Tentacle

Basically the Tentacle is Dan Armstrong Green Ringer with a few value changes.

Now for those of you that liked the idea of building a Hoof Reaper, which I mentioned when I posted the layout for the Tone Reaper, the Tentacle should go in between the Hoof and Tone Reaper for the Octave effect. So for all the disciples of fuzz out there, pair this your favorite fuzz for some crazy octave up fuzzy goodness.

Direct from the source:

The Tentacle is a classic analog octave up effect. It is the very same octave from our beloved Hoof Reaper pedal. We got so many requests to make this a stand-alone unit that we just had to make it a reality. You can now add an excellent, swelling octave up to anything your heart desires! Pair it with your favorite fuzz, strap on a headband and unleash your inner Jammy Hendrix. Put it in front of another octave up and blow your amp's mind. Throw it in the effects loop of a delay and marvel at what happens (then tell us, we’d like to know too). What’s better? It has no controls! Nothing to worry about at all here, just hit the switch and go for it. The Tentacle is an analog octave up, the effect will become much more pronounced when using your neck pickup and playing above the 12th fret.

Charge Pump Extravaganza

Here's something I've been looking for for awhile now for a project I've got in the works, and figured some of you guys may be looking for the same thing. They're based off of the schematic published by the one and only R.G. Keen, found here.

Layout 1: +9V to +17V

Layout 2: +9V to +25V

Layout 3: +9V to +33V

Remember to watch your electrolytics voltage rating, especially with the +33V charge pump
Note: You can NOT substitute the MAX1044 for 7660s or NE555 IC.

Earthquaker Devices The Depths

Direct from the source:

Ahoy! Welcome to your new Depths Optical Vibe Machine! The Depths is our take on the classic optical vibe circuit. Now you can swab the decks with the same lush, pulsating, three-dimensional swirling sound you know and love, with some modern accouterments for all you land-lubbers out there.

The Depths is optimized for use with all kinds of instruments, pickups, and to play well with dirt, so nobody’s left waiting on shore. If it’s got a ¼” output, plug it in and get deep!

 In addition to the classic vibe controls, the Depths features unique controls for “Voice” and “Throb.” The “Voice” control adjusts the midrange focus of the Depths, which is perfect for tailoring the effect to your particular instrument. Clockwise, you’ll hear a fuller sound with a low-end focus. Counter-clockwise, you’ll hear a thinner, spikier sound with a forward upper-midrange bite.  The “Throb” knob adds a hefty subharmonic low-end pulse to the vibrato signal, which is especially useful on synthesizers and the bass guitar. It sounds great with a little bit of dirt on the neck pickup of a guitar, too! This works best with the “Voice” turned counter-clockwise for a warmer tone.

The Depths’ “Intensity” and “Rate” controls are dialed in to give you the classic optical vibe sound at more modest settings, but dive in deeper and you’ll find anything from a smooth ultra-slow warble to sharp, speedy bursts! Also, the “Level” control has tons of output above unity on tap to combat the perceived volume loss of most vibe pedals, so your tone is always above water. And, if 9v isn’t enough to keep you afloat, the Depths may be powered at 18v for a stiffer tone with more headroom and sparkle.

We've got 2 layouts for you.

Layout 1: We've got the the LFO off the main board to hopefully prevent the dreaded LFO tick. Should fit in a 125b like the original. Downside is that there is more offboard wiring you will need to do.

Layout 2: Slightly larger board, with the LFO on the main board. You shouldn't get any ticking, and you'll save on having to deal with the extra offboard wiring.

Wattson Classic Electrons EFY-6

Found this on TGP from the man himself when he was first releasing it:

Basically, it's an FY-6 with some extra bells and whistles in a "pedal board friendly" enclosure. The official name is the EFY-6, with "E" meaning "Enhanced".
The "Expander" knob has been renamed "Fuzz", and the "Balance" knob has been renamed "Gain", as these more clearly describe what these controls do.

We fiddled with the differential amp and worked out a way to be able to adjust the amplitude of half of the cycles coming out of it. Turn it all the way down and voila! No octave step up! Turn it all the way up and it sounds like an original FY-6. In between you can adjust for however much chord smashing synthy overtones you want. This knob is appropriately called "Octave".

A cross-fade knob was installed between the mid-scoop filter and the voltage divider that used to be connected to a switch labeled "Tone". You can now blend between the two tone settings. Obviously, this knob is called "Tone".

The final stage got a gain boost so that the maximum output signal level is more than 4X the maximum output level of the original FY-6, or more than double the volume.

With the knobs set appropriately, it will sound just like an FY-6. Move the "Octave" or "Tone" knobs away from their limits and you can get tones not possible with the original FY-6.

Unfortunately, Wattson Classic Electronics has shutdown, and while they were around they made very few of these. What brought me to find out about this pedal is that the guys of SUNN O)))) have been known to use this pedal.
