Capitalist Death Cult Just. Give. Up. V2

 Another contribution by Chris. This time he made some improvements and addons on a rare and wild Death by Audio circuit. Tone houndz...stay away!

I don't know if this warrants its own post but I wanted to show it to you anyway since I was the one who verified your purple card drawing.

Since I built that up I wasn't happy with the bleed through in bypass that sometimes happens with the LM567. So I used the old "millennium bypass" trick of adding a mosfet to handle the LED switching so that you can use only a DPDT for true bypass with an indicator light. THEN I used the now-vacant set of poles on a 3PDT to connect/disconnect the power supply to the LM567 when the circuit is bypassed. So NO NOISE! I also added the master volume, because if ANY circuit needs it, it is this loud beast. Then I put the frequency pot (which I cut down to 10k) on a switched expression jack so that you can get foot-controlled crazy pitch-wah sounds with a standard TRS expression pedal like an inexpensive m-audio or nektar controller. Anything more than 15-20k of resistance for the frequency control just takes you into slower and slower chopped/tremolo territory. And the 10k pot still allows for some of that in the toe up/CCW position and all of the pitch control as you turn the knob up/put the treadle down.

 

 I added a toggle to change the resistance on the frequency sweep - this allows for a low range and high range mode on the frequency. Since most expression pedals have 10k pots, I wanted to keep the frequency pot at 10k too so that the sweep matches whether you are using the knob or an exp pedal.

 Schematic and setup guide avaiable HERE.

And as usual, don't hesistate to order some boards from Deadend Fx.

Royal CW-1 Cosmo Wah Machine

 Now this is some crazy stuff! How about a wah / ringmodulator with vibrato tails???

The schematic is avaiable at DeadEnd Fx.

Note that the Wah/Cosmo Select switch is the stock 2P6T rotary for this layout.

 

 

Electro Harmonix Frequency Analyzer - Modern version

 The modern version of EHX Frequency Analyzer. The ICL8083 IC is obsolete but there is still some vendors that have it in stock. Came out taller than expected since I wanted the bipolar voltage doubler circuit on the same board as the main circuit. But it will fit sideways in a BB enclosure...

 900 post. Phew. I think it is time for a couple of weeks break do deal with "outside world" issues.:-o. Will still log in here now and then and eventually upload something if something really interesting shows up.

But here is a cool design from Lastgasp Art traced by Deadend FX, a bitcrucher/tremolo,/ringmod/envelope follower...thing.  Schematic is avaiable HERE.

Bluff Chill Devices Hyper Light V1

 A quite interesting PT2399 delay with a ringmod circuit in the wet path for dirty and robotic delay repeats. Schematic is avaiable HERE. 

Pladask Elektrisk Odd Amplitude Modulator / Noise Synth

 A liitle noise thingy designed by Knutolai at Pladask Elektrisk. A ring modulator based som Tim Escobedos Thing Modulator with Starve control, hard clipping diodes, cross over distortion diodes and a feedback switch...somethhing to keep the neighbours happy.

Parasit Studio The Corruptor V3

 Latest version (V3) of a square wave fuzz with a PLL IC to achieve ring modulation.

Schematic and info is avaiable HERE.

 

 

Maestro RM-1A Ring Modulator

 A requested circuit but bear in mind that it is rather big, has an onboard charge pump for 15v-15v operation, and has a quite complicated setup due to five multiturn trimmers.

I've omitted the (for now) the Osc, Pitch, Carrier and Modulation jacks but might add it later on if is requested but it will be an "offboard wiring extravaganza".

 Schematic is avaiable HERE

Trimper setup is avaiable  HERE

Jen HF Modulator

NOTE! Most schematics has a 220pF cap instead of 2,2nF left to Q1. 220pF is reported to work much better. Verified by Mulekicker.
