ZVex Super Duper 2 in 1

Another popular one from Zacky baby.  And on the plus side the layout ended up looking like a spaceship out of Gradius 3 :o) (showing my age there!)


Hermida Mosferatu - 3 knob

3 knob versions of this higher gain brother of the Zendrive. 


Jetter Gain Stage Red

Hmmm this looks familiar!

Devi Ever Karaoke Party

A quicky for you Devi fans.  This is actually a really good sounding overdrive for such a low parts count.  I did a layout for this previously based on a guessed schematic but this is the corrected versions from Devi's schematic.



Monster Effects Swamp Thang

I did this layout based on Dirk's schematic here.  Now verified.

Proco Rat




And a slightly more compact layout

Bigfoot FX Magnavibe

I'm bored of dirt layouts (until the next one!) :o)  Check the notes on the LED/LDR

DAM Drag'n'Fly

Another one requested by a few people.  I did a tagboard layout a couple of years ago but it was based on an incorrect schematic so I pulled it and have been meaning to do this one for a while now.

Compact version



Customary mojo version


Lovepedal Delux Sixty



Anti-popping resistor added to the input after the discussions below:

ZVex Fuzz Factory vero

Another that I thought I'd already posted.  I'll add a more compact layout in the next day or so

Lovepedal English Gent

Is that the lot yet?

Univox Super Fuzz

Note the pin layout required for the transistors.  This will accommodate many modern NPN silicon transistors, but you will need to either alter the layout or twist over pins if using transistors with a different pin layout like the 2SC828s used in the original.  One for a 1590BB, but I'll do a 1590B friendly version at some point.


BJFE Sea Blue EQ

I did this one a while ago and it has been posted on a number of forums but just realised I haven't shared it here yet.

ZVex Box of Metal

Another one to keep you busy for a while.  This version is the effect only and no gate so you'll have to use an ISP Decimator or something with it if it's noisy :o)

Hermida Zendrive

Another popular pedal and rightly so, this is a great sounding overdrive.

EHX IC Big Muff

I wanted to try this one out with a quad opamp and so thought I'd put together a couple of layouts, one for the 1977 version and one for the 1978 version with a tone bypass switch.

I have done a version of the 77 with all the diodes laid out on the board, but to keep the width down to allow this to be mounted in a 1590B box I decided to simplify the diode layout, so D1 and D4 are each 3 x 1N4148 diodes in series.  They're small enough to allow you to make these groups of 3 up yourself (and maybe cover them with shrink tubing) without looking unweildy on the board, so I thought it made the most sense to keep the layout as compact as possible.

Both layouts were put together with the TL074 opamp in mind, but if you use a non-fet based quad opamp then the 1M resistor from pin 10 to the supply rail should be changed to 820K.

Layouts were based on analogguru's schematics but are currently unverified, so if you build this up then please let us know how you get on.

IC 77



IC78

With 2 position SPDT toggle switch for Tone Bypass

Mini JFET Blend

A simple mini blend layout based on Sean's JFET schematic here:

http://seanm.ca/stomp/minblend.html

Will easily fit in a 1590A box and I probably wouldn't even use a stomp switch with this because in the unblended position of the pot, this will essentially be just a JFET buffer.  You could always add a mini toggle to bypass it completely if you wanted to.

This will make a useful little tool to experiment with blending dry and effect signals together, or to allow you to use a digital effect 100% wet so your dry signal isn't being digitised.

Keeler Pull

I posted this a while ago but someone said they had a problem with the build and so I pulled it and then promptly forgot!  I've just noticed that since then the same guy confirmed the layout is good so I may as well post it up again.

ROG Whisker Biscuit

I thought a few Big Muff fans who were looking for something a little different may be interested in this.  From the runoffgroove website: "The Whisker Biscuit is a hybrid of the Bazz Fuss and the Big Muff Pi. A single Bazz Fuss stage replaces the two clipping stages of the BMP. Smooth, super-long sustain, and good clean-up with the guitar volume knob make this circuit an interesting alternative to the standard BMP."



They suggest that for "a velvet-like reduced treble sound" you can add a 47pf cap (or choose a value to taste) in parallel with the 470k Base/Collector resistors in Q1 and Q3.  Like you see in the Big Muff circuit.

DAM Sonic Titan with modified tone stack

A few people don't like the tone control on the Sonic Titan, so this is a modification based on Skinpimp's Sonic Samurai.  Apart from the tone stack modifications, all the other Titan components and values remain true to the original.

DAM Sonic Titan

I did a mojo axial layout for this a while ago and wanted a more compact layout too, so here it is.  If anyone wants the axial version let me know and I'll dig it out and post it as well.



And one for DSG pinout JFETs such as the 2N5457, 2N5458 or J201

DAM Meathead Deluxe

A few people have requested this so I thought I'd get one put together.  Based on my previous layout but with some obvious differences due to component changes.




And a mojo version for those who prefer it

Lovepedal Super 6

The Lovepedal library continues! :o)



More compact version without the unnecessary 100nF filter cap

DAM Super Bee

One requested by fx40b and including two layouts, one compact and one for DAM type axial mojo goodness!  This isn't yet verified and so if you make it successfully then please let us know.
