Earthquaker Disaster Transport Jr

Had a sleepless night, so I decided to knockout some new layouts before the end of the new year. This one kicked my ass a bit, but I got it as small as I could. a nice sounding delay, that's similar in architecture to the Deep Blue Delay. It's a nice sounding warm, natural delay.

From the source:

The Disaster Transport JR is an analog voiced digital delay with 625ms delay time with an all analog dry signal path and true bypass switching. It was designed as an anti-modern delay for those who appreciate a nice vintage tape echo with all it’s peculiarities. Its unique tone control doubles as a noise filter on longer delay settings and really helps the delay shine with a dirty signal. The mix control allows you to boost the effected signal to nearly 4x the original signal level and the repeats control goes from one signal repeat to near infinite repeats all the way through to self oscillation.

Mix: Sets the output level of the effected signal. This should be treated as a gain control/master volume for the delay line. Unity is around noon and everything above noon will boost the delayed signal louder than the original. This is a gain control so, like any pedal with a lot of gain, a hint of noise and distortion at max setting is completely normal.

Tone: Most delay pedals are heavily filtered at the output to remove the clock noise and other unwanted hash that is common from extending the range of the delay time beyond the limit of the circuitry. This usually leaves the delay sounding dark, muddy and disappear when hitting it with dirt. The Disaster Transport has done away with a lot of the heavy filtering and replaced it with a tone control which allows the user to choose their desired sound and results in more natural tape-like repeats. The tone control is at it’s darkest fully counter clockwise and brightens as you turn it clockwise. A good rule of thumb is to leave the tone control between off (fully counter clockwise) and noon at longer delay times. This will remove all the common noise from hyper-extending the circuit.

Time: From about 30ms fully counter clockwise to about 625ms fully clockwise.
Repeats: Sets the regeneration of the delay line. From one single repeat fully counter clockwise, subtle repeats around 9 O’clock, strong naturally decaying repeats at noon, near infinite repeats around 2 O’clock and full on self oscillation fully clock- wise.



A version of this pedal was requested with tails, so I took a look at the Deep Blue Delay, which this is based off of, and made the same modifications.  To have tails, you don't use a 3PDT switch and the usual stomp switch wiring, you're going to use a DPDT switch  with the input and output wires going directly to the sockets.  With tails the stomp here will cut new signal going into the PT2399 and so when bypassed the output of the PT2399 will continue repeating with the last input it received and the repeats continue, and IC1 will then act as a buffered bypass.  You may want to to swap the 47K resistor at pin 7 of IC1 for a 50K trimmer so you can adjust the buffered bypass level so you can have to perfect unity with your bypassed signal.  Another alternative is that you can add a second stomp to true bypass the whole thing  which will give you the option to mechanically bypass the effect as usual, or simply bypass with tails when you want.

DOD Carcosa Fuzz

Anders knocked out a layout for this a few days ago on the forum and beat me to it, but I still wanted to whip up a layout for the main page.

From the Source:

The DOD Carcosa Fuzz is a doorway into an alternate fuzz universe, where classic tones of legend coexist with splattered and shattered Pollock abstractions. Combining the Carcosa's wide-ranging AFTER bias control with two toggle positions creates tones that range from porcine fatness to dessicated shards. This versatility makes the Carcosa Fuzz a good companion for dirty or clean amps. True bypass, tons of output, and the visage of the King in Yellow sets the stage for fuzzy madness.
The DOD Carcosa Fuzz has an exaggerated mid-range and treble character that help it stand out in a mix. It has been designed to cut through a dense and heavy band but still have great note articulation with chords. However, when extreme bias (AFTER) ranges are selected many wild and over-the-top sounds are possible.

KMA Audio Machines Fuzzly Bear

From the source:

Holy Spirit of the forest, fuzzly bear is here. Kick the Switch to unleash the beast. The sound of this fuzz-pedal is influenced by an old underrated box of the 1970, the classic Jordan Bosstone. The main reason why it did not conquer the world's guitar players like other effects was the massive lack of bass.

We refined the circuit to get an old school sound with a modern Twist. First of all we brought back the low end and added a bias control to explore new capabilities of the forgotten pedal. The essential SKIN/MEAT knob controls the bias of the circuit. You can dial in a sharp skinny fuzzy tone or a thick and meaty wall of furry. The GAIN control delivers a whole range of different fuzz shapes. Back it off to get a dirty chunky overdriven tone, turn it up and your tone becomes thicker and thicker. Set the gain fully clockwise and magic will happen: The smooth decay turns into a starved and gated fuzz sound, perfect for classic tunes. Check out the demo, get bitten.

SolidGoldFx If 6 Was 9 BC183CC

From the source:

The If 6 Was 9 is a modern interpretation of the classic late 60's, early 70's, Fuzz Face circuit with a few updates and modifications. At the heart of the If 6 Was 9 is a pair of hand selected, new old stock BC183 transistors. These transistors offer a great balance of soul and attitude producing a unique fuzz character that is rich and smooth with excellent sustain and exceptional volume clean up. Vintage spec carbon comp resistors further enhance the warmth of the core circuit while the addition of an external bias control and the 2-way tone switch provide maximum versatility and allow for quick adjustment of the overall fuzz texture. Although the If 6 Was 9 has a distinctly vintage flavour it is capable of generating an extremely wide range of useful fuzz sounds, from full bodied and round to more gated and splatty. If soulful fuzz is your thing, the If 6 Was 9 BC183CC will be a fantastic sounding and gorgeous addition to your arsenal.

Budda Om Overdrive

From the source:

With the Budda Om Overdrive guitar pedal, you won't have to worry about your guitar tone not being able to cut through the mix. With plenty of gain provided in this tight compacted box, you get a pedal perfect for anything from an old-school crunch to mordern fuzz. Put the Budda Om Overdrive guitar pedal in your signal chain, and you'll notice the jaw-dropping difference it has on your amp. The classic 3-knob user interface focuses on the EQ while giving you organic control over your overdrive tone. Check out the Budda Om Overdrive guitar pedal for that missing ingredient!

BJFE Baby Blue OD

The BJFE Baby Blue OD is described as a dynamic pre-amp tube distortion, although it is technically more of a fuzz pedal with dynamic overdrive features.  It is a killer fuzzy OD with a ton of dynamic and tonal range.

So according to the thread over at FSB there's no mention of the specific JFETs in the original other than they're N-JFET. It's possible they're either BF244 or 2N5952 both of which Bjorn is known to use. So I decided to make 2 layouts, one with a DGS pinout (BF244) and one with DSG (2N5952) so either can be made. There is also a question as to whether or not the 47k resistor going from Drain of Q1 to the power rail actually being 14.7k like the drains of Q2 and Q3, so as of now if you build this you may want to socket that resistor so you can try both and see which sounds better.

Madbean Zombii / ZVex Fat Fuzz Factory

Tweaked Mark's original compact layout according to the info i found on the fat mode switch. Should be good to go.

Foxx / Sears Phasing Pedal

Here is a monster layout for a 70s phaser made famous by Brian May.
No many infos/videos around.
You can find the schematic in the original DIY thread here and FSB's here.
To draw a layout for this wasn't easy. To build it would be as difficult.
Double check everything is correct before starting.

There are no great quality videos but I'll add a couple just to give an idea.
