EarthQuaker Devices Crimson Drive

A couple of the electro caps look to be the wrong way round to me but this is definitely as per the scheme and it was by Dirk and so a trusted source. 

Info about the original:

The EarthQuaker Devices Crimson Drive is an all-analog, dynamic overdrive that uses a germanium transistor and vintage germanium diodes to create an abundant, open sounding tone that simply isn’t available through FET or Opamp driven effects. The Crimson Drive works beautifully with both humbucker and single coil pickups to get the most out of your amplifier by pushing your preamp tubes into natural overdrive with a choice bit of distorted input boost. The Gain knob gives you control over a broad sweep of harmonically rich effects from a well-textured treble boost to an abundance of viscerally satisfying plexi grit. The low pass Tone control dials back the high end while the Level control keeps the damage to a reasonable level. The Crimson Drive responds to your playing and cleans up with your guitar’s volume control. It is Made in the USA, wired for true bypass, and operates on a standard 9vDC power supply or a battery. 

EHX Double Muff

Classic dual overdrive. The original 1969 plug-in Muff Fuzz had just a touch of overdrive and sounded like a vintage amp with a slightly torn speaker. We paired two of these together in one box to create the Double Muff. Use just one Muff for a hint of milky distortion, or cascade the second Muff for over-the-top overdrive that turns the milk into cream. Two distortions in one!

Skreddy Top Fuel

Another great fuzz pedal from Marc, and I felt a nice one to add to our collection.  I thought with 8 transistors this would be a bitch to get into a 1590B as a vero layout, but it turned out pretty comfortable in the end.

Info about the original:

Skreddy Pedals™ Top Fuel:
strikes a balance between high gain, sustaining distortion and articulation.

    First, I trim out the woofy, mushy, congested bass.  Then amplify (a lot) and distort using mosfet soft clipping (twice), for a fine-toothed, modern, tube-like distortion character.  Then trim out the harsh and fizzy high end and use a mid-hump tone stack that's centered around 700Hz.

    The string attack is always preserved throughout the entire range of the fretboard, regardless of the sustain level.  Tonal emphasis is placed on the midrange in order to showcase the player's technique.

Devi Ever Legends of Fuzz

Another one from our friend Geiri, thanks for this again mate :o)
Info about the original:

The Bit : Legend of Fuzz has been compared to the Shin-ei Companion FY-2 fuzz, but with a stronger gate on circuit settings.  Some say, it’s a sound that haunts you at night… the desperate 8 bit beep that reminds you your heart is empty and you are close to death. Nostalgia is a lie. It tells you some how something that was is better than what is or what could be. Here it is though. A fuzz that elicits the sound of old video games… I guess. I mean, a lot of my gated fuzzes can do that for you. This one likes to particularly twist your guitar signal in a way that’s relatively like a saw tooth… a pretty fucked up saw tooth. Maybe we’ll define a new kind of saw tooth wave shape now… shark tooth, because that’s what this fuzz sounds like… a shark’s mouth full of teeth ready to clench down, and it doesn’t matter if a few are lost while eating cold rusted steel from a 1950′s buick rotting on the bottom of the ocean, because there is more where that came from. Unmerciful bastard of a fuzz really… just like that beep beep beep counting down the moments till your inevitable death

Opamp 3 channel splitter/mixer ON HOLD

Updated 6th February 2014

I have a TC Electronic G-Force and Eventide Eclipse in the parallel effects loop of my amp and use a rack mixer to keep them in parallel with each other, and so allow me to use them both 100% wet and so avoid having to digitize my dry signal.  I do have OCD about keeping my core dry signal out of the digital domain completely.

But I also have an Eventide Pitchfactor and would like to put this in too, and although the rack mixer can accomodate 4 in and 4 out, adding the Pitchfactor to an already limited rack space would be a pain, so I wanted to make a little 3 channel utility splitter/mixer to use instead of the rack mixer to save 1U and allow me to put two pedal trays in my 6U rack.

I used the splitter scheme you can see at Paul in the Lab, and a generic mixer circuit I found so that everything can be done with one quad opamp.  I may even make this with 3.5mm jacks for the send and returns, make up my own high quality cables and then this will all fit comfortably in a 1590B.  It would pretty much be a set and forget utility for me so I suppose I could even use trimmers instead of pots, set the levels and tuck it away somewhere.  So I thought I'd add it here and it may be useful for others to adapt for their own uses.
