Earthquaker Devices Space Spiral

Original info:

"The Space Spiral is a dark and dreamy modulated delay designed to take you across the highways of fantasy. While the delay may be designed around a “dawn of digital” echo processor, the sound is out of this world, man. If you are a fan of the dreary echoes produced by old oil can delays or the ethereal sound of a well-loved tape delay, the Space Spiral is totally going to tickle your tone bone.

The Space Spiral’s delay time ranges from a tight 30ms to a fast and loose 600ms."

Schematic, pcb and info available on pedalpcb website here.
It should fit in a 125B size enclosure.

Keeley Magnetic Echo

Original info:
"The Mag-Echo pedal simulates tube tape echo sounds by using the delay circuit and a little bit of modulation.  Tape echos have long been regarded as a warm and very guitar friendly form of delay.  The Mag-Echo achieves similar results by using a touch of Lo-Fi delay, a slightly filtered echo response to keep things warm, and some modulation.  Modulation, or “Wow and Flutter” in the tape world is a slight pitch shift or wavering that occurs as the tape is pulled across the heads.  The modulation we use is similar to what we use in our Seafoam Chorus, a slight wavering of pitch on the trails of the repeats.  With a simple set of controls for the delay – Time, Regen, and Level and with the “Wow and Flutter” controls – Depth and Rate you can create some very vintage or rather unique tones"

Fortin Amplification Zuul

Original info:
"ZUUL is the most transparent noise gate on the market! Studio quality specifications with simple straight forward operation. The ZUUL’s threshold knob also controls the dynamics of the gate circuit. Perfect for guitar, bass or any signal source as it has studio quality specifications. Use in front of an amplifier or in a series effects loop. Dual colour LED for visual feedback gating action: Green = Open, Orange = Closed, Off = Bypass. The KEY input signal can be directly from your guitar (ex. split from ROACH or SPLIFF) or other signal source which lets you go from clean to high gain without changing the Threshold knob. This powerful feature lets you control the gate with a different signal than what flows through the input/output jacks of the ZUUL. Side switch or internal jumper to change the threshold range if you are injecting a large signal into the input and not using the key input"

Ethos TWE-1

Info:
"Inspired by the Trainwreck Express amplifier (built by the late Ken Fischer), the TWE-1 is solid-state pedal designed to emulate the touch-responsiveness and clean-to-overdriven range you get from a high-grade tube amp. Along with Volume, Hi Cut, and Gain controls, the pedal has 3-position Cab switch (4x12, 2x12, off), a Presence switch that provides three levels of high-frequency boost (post OD), a Voice switch (Traditional and Modern British), and a bypassable Brite switch that provides two levels of high-frequency boost (pre OD).
The TWE-1 with its Gain at noon or higher responded in an amp-like way to changes in guitar volume and picking strength, delivering everything from gritty cleans to richly saturated distortion textures. Thanks to its strong output, the TWE-1 is suitable for clean boosting too. All good stuff, but the standout feature of the TWE-1 is its powerful tone-shaping ability. The Hi-Cut knob attenuates treble when turned clockwise, and the Brite switch makes it easy to get the appropriate sparkle with humbuckers or single-coils. The Cab switch beefs up the low-end significantly in the 4x12 position (I felt the 2x12 setting sounded best with my Deluxe), and the Voice switch lets you choose between a thicker tone in the “M” position or one with more upper-midrange emphasis in the “T” setting. The Presence switch set to Hi restores shimmer when the Hi Cut control is turned up (a cool sound in itself), and between all of these functions, the TWE-1 certainly answers the needs of players who want a compact OD pedal with exceptional sound and flexibility."
The layout should fit in a 125B size box.

VFE Old School Tremolo

Original Info:
"Our OLD SCHOOL tremolo pedal recalls the luxurious tremolo sounds of vintage tube amps. Derived from a rich sounding, but feature-limited tremolo circuit from the 1960s, we added extra range to both speed & depth controls. But we did not stop there! We added two unique circuits - one to starve the circuit to add grit & chop, and another that can adjust the speed or depth based on your playing dynamics."

FV-1 Pedal

BuGG from Pedalpcb.com has created an EZ FV-1 module for vero layouts.
It is available here: http://www.pedalpcb.com/product/ezfv1.
This is what he wrote about this circuit in our Forum / Requests section (schematic available there):

"This is a fairly straightforward single-algorithm FV-1 circuit, it would be a nice starting point for learning how to work with the FV-1.
For easy stripboard building the PedalPCB EZ FV-1 module is available, a through-hole FV-1 module for stripboard/breadboard layouts.  (ready to use, no SMD soldering required)
The pin spacing is standard 0.1" x 0.6" so it can be handled like a standard PDIP-28 (WIDE) IC.  
The 24LC23A must be loaded with an algorithm in bank 0, although multiple switchable programs are possible by pulling pins 16, 17, and 18 high (corresponding to the binary encoded bank number).
The internal algorithms can also be used by grounding pin 13.
There will be pre-programmed EEPROMs available soon for those who just want to build the thing and not fool around with programming as well."

Baja ENG Overdrive

Bajaman's overdrive circuit based on the Engl 530 preamp with switchable tone stack.
Original thread and schematic available on the FSB forum here.
The layout should fit in a 125B box.

09/07/2018 Layout Updated! Inverted Treble and Bass pots' lugs. Changed 390p cap from TL062 pin 5 to 470p. Changed 1K resistor next to 22uF cap to 1K5.
22K resistor between Gain 1 and Gain 3 goes from Gain 1 to 15n/10K 3 rows below instead of Gain 3. 22K above TL062 pin 8 needs to move down one row between 10K/22K and VBias.

Baja MDR Overdrive

Bajaman's overdrive/distortion circuit based on the Mesa Dual Rectifier high gain channel with switchable tone stack.
Original thread and schematic available on the FSB forum here.
The layout should fit in a 1590B box.

Baja JVM Overdrive

This is based on a Marshall JVM410.
You can find Bajaman's original thread and schematic on the FSB forum here.
There are two versions:
First one with just one toggle switch to select between Cruch, OD1 and OD2.
The second one uses separate footswitches, Gains and Levels.
You need to add an extra pole for LEDs.
Can use any small signal N channel JFet for the buffers (mind the pinout).

Jext Telez White Pedal

"A boutique pedal homage to the unique onboard overdrive circuit in vintage solid state Vox Conqueror amps that George Harrison used on the White Album and other Beatles recordings. The White Pedal has four knobs that control volume (overdrive), gain (fuzz), treble cut, and a bass cut knob that acts as a mid-boost, while a fifth knob (the Yoko knob) selects the midrange frequency to boost for a parked wah sound"

VFE Pedals Dragon Hound

"The DRAGON HOUND is a dual overdrive + distortion pedal that combines the core circuits from the Alpha Dog and Pale Horse into one unique dirt box. Each circuit has a dedicated drive control, and the blend control can dial in saturated distortion tones that retain the clarity of an overdrive."
You can find their original pedal (now discontinued) on their website here and the original schematic here.

Friedman Dirty Shirley

Original info:
"The Friedman Dirty Shirley all-tube amp is well known for being one of the most flexible and touch-responsive single-channel amplifiers on the market. Now you can get that same tonal versatility, sensitivity and harmonically rich overdrive in a pedal. The Dirty Shirley Overdrive packs the same intuitive control set as the amplifier, allowing you to dial in your perfect shade of rock in no time. It doesn't matter if you want a high-output cleaner tone for pushing your amp hard or a thick gritty drive that will sit well in any classic to modern rock band, a sweep of the gain control easily gets you there. If you ever want reign in the low end, for a punchier feel, simply flip the side-mounted Tight switch and away you go. If you want to experience the amp’s accolade-garnering tone in the convenience of a pedal, put the Dirty Shirley Overdrive on your board today.
British rock at its best
Though the Dirty Shirley overdrive can scream with an unabashedly rock 'n' roll voice, you'll be surprised at how truly versatile it is. To get more out of the amp you already have, roll the pedal's gain knob back, crank the volume and get a killer dirty boost. And of course, roll up the gain and witness how well the pedal responds to every touch and manipulation of your guitar's controls.
● Friedman Dirty Shirley amp tone in a compact pedal format
● Responds to guitar controls and picking nuance exactly like the amp
● Gain control takes you from gritty to hard rock in no time
Ready for your rig
The Dirty Shirley Overdrive pedal delivers tube like tone in a small pedal format which can be used either into a clean amp or to boost an already over-driven amp. If your amp, or other overdrive gets a bit loose in the low end, throw ON the Dirty Shirley's Tight switch to bring back the percussive attack you crave"

EarthQuaker Devices Palisades

Original info:
"The Palisades is something we said we would never do… an overdrive based on the legendary TS808! Gasp! The horror! Another tubes creamer?? In 2014?? Really?? After loads of requests we finally buckled. We ran tests with every popular clone on the market as well as several vintage originals, compared, contrasted and took loads of notes. It was exhausting but informative. In the end, we threw it all away, used our ears and came up with what we feel is the most versatile relative of the 808 available today.
With 6 different clipping voices, 5 bandwidth settings and 2 gain channels you will be hard-pressed to not find a setting that will wipe every mid-boosting overdrive off your board. The clipping voices determine how transparent and open or tight and crunchy the distortion is. They will vary drastically depending on where the gain is set, what channel is active and how much bandwidth is being used. The bandwidth sets the frequency response of the distortion and goes from thin, light and clean through fat heavy and crunchy. It may very well be the single most important control the palisades has and what really sets it apart.
Gain A is a lower gain channel with a wider range of grit that is great for strumming open chords. Gain B is a higher gain channel with a tighter range that is great for palm muting and/or shredding solos. The Palisades also has a foot switchable volume boost with adjustable level to take it over the top when you want to throw your foot up on the monitor and rip your sweet leads… or maybe just push the front end of you amp a little harder. Not enough? How about a normal/bright switch to mix and match the overall tone to different amps and guitars. Still not enough? OK then, how about a buffer on/off switch to tighten up the tone and make it sparkle when set to “ON” or warm it up and make it sag when set to “OFF”."

Diezel VH4

"Unlike traditional overdrive stomp boxes, the VH4 Pedal is a true preamp which delivers an authentic representation of its namesake – real Diezel tone – not emulated, not modeled, but sincerely reproduced. The entire signal architecture is faithful to the original: Bass, Mid, Treble and variable Deep and Presence controls allow you to tailor the uniquely Diezel Overdrive character. The command found in the Gain control gives a player everything they will ever need with lower gain settings producing the classic Diezel sparkle and chime to saturated mid-gain sounds, to scorching Diezel leads by cranking it all the way up.

As close to the original VH4 preamp, the VH4 pedal can be used as either an overdrive or as a standalone preamp to feed into your amps power section. What players take away by going direct into the power amp is all the dynamic, unfiltered Diezel tone by simply plugging into your amplifiers clean channel. Two outputs are provided with the first intended to connect to the front of a guitar amplifier and the second allows for a connection to a line-level power amp or power section of your amp via the Effects Return."
