Holy Island Audio Cannibal Pride Drone Synth

 Chris have done it again...

"Gwion of Holy Island Audio builds awesome stuff and, included in the package if you purchased the debut release from Gwion's band, Smothering, is a DIY PCB for a three oscillator drone synth called the Cannibal Pride. This is that synth, and it sounds KILLER - keep in mind that, as this is a sound source and not an effect, there is of course, no input."

BJFe Universal Reverb V2 / Capitalist Death Cult Actual G*ddamned Springs

 Heavily modified revebr unit by BJFe, treated by Chris Stelloh.

 

A couple of the tweaks are from Björn - in particular, the 2k2 resistor from the source of Q1 to ground. Lowering that value fixes a volume drop that can happen when the 50k dwell pot is maxed. I replaced the second dwell pot with a 10 ohm fixed resistor, so that it is almost at maximum. I also added a flat-mids BMP tone control and BC337 recovery stage that sounds really great paired with this circuit. Using a PN3269a in Q2 can squeal with feedback (a GOOD thing in my world) so dialing in the 10k output trimpot is a necessary step. It is possible to set it so that it only howls when the dwell+mix are turned to maximum. The charge pump is something I redrew from an old tagboard layout. The 555 doubler puts out 30mA of current which this verb circuit needs most of (the schematic says it draws around 20mA, and that was before I added the extra transistor) no matter what voltage you are running it at.

1776 Multiplex Delay Modulation Add-on

 A little useful modulation daughterboard for your delay circuits. Created by the one and only Chris Stelloh.

I originally made this for Ben Spinks, who verified it. It's the modulation daughterboard for the 1776 Effects Multiplex delay and it works pretty well with just about any PT2399 delay circuit. I've listed my preferred values as well as the originals from the build document. You can add a toggle between the mod depth and the delay pot to turn it off and on, but if you simply max the speed/rate knob, the modulation is no longer audible and the rate LED is static.

Claybridge Fuzzmaster Mk. IV

 How about an austrailian fuzz box from the late 60s?

Amazing that there is still undiscovered old circuits around...

Note that pot values and tapers are still unconfirmed but all of them is most likely 500k.

Electro Harmonix Bass Big Muff

 Per request. Was a bit hesistant to upload this since there are three missing cap values. But socketing some values should get you close enough. magus femar did some socketing and ended up with some values that works well. See the notes below the layout.  Note that I omitted the ferrite beads since they are overkill and I also omitted the direct output jack.

Seppuku Fx/Jordan Fontaine Memory Lapse

 Another contribution by Jordan. Thanks mate!

I was playing with the Seppuku Fx Memory Loss that you had posted and made some adjustments for more versatility. The schematic we all have to work from is so sketchy I thought people might enjoy a thorough series of mods to it. 

S

First off I added a Mix control. It could probably be done better and would love to hear suggestions. 

The C Taper for Stability gives easier adjustment over where the latch up occurs in playing dynamics. 

I set values at the Filter control. The on/off/on gives a clean delay, dirty repeats and very dirty repeats. If you placed a 1u in either C2 or C3 it creates a totally nuts fuzz.

I set components around the feedback and surge control to taste. 

The increased Time pot is for longer delay times, why wouldn't we want longer delay times?!

I 86'd the switch for the LM386/Pins 1 & 8. I'm not going to use it but it wouldn't be hard for someone to wire it in.

The layout is not verified. It is the result of fixing the board I built from my original layout. 

Hopefully no one minds a few diagonal caps.

Frost Giant Electronics Little Acid Fuzz

 

 Phew, loys of work lately so not much time for the blog and building lataely. A few people have sent me some new traces and new layouts. These will be uploaded today. First out is Little Acid Fuzz by Frost Giant Electronics.

Another Frost Giant PCB traced by Sergio. Based on the op amp version of the Little Big Muff from the late 70s. The internal Tone trimmer can easily be moved to the outside for a 2-knobber.

Chris Stelloh managed to squeeze in the power module mentioned in the Aion build docs. Hopefully it will solve the issues with power and noise.
