Basically a lot of the stuff posted in various forums about "buffered" and "unbuffered" variants of the CD4049 is simply wrong. The crucial characteristic is that some chips are INVERTING and some are NONINVERTING.<br /><br />The "U" in the part numbers refers to inverting versions.<br /><br />The variant apparently needed for The Great Destroyer is the CD4049BE or equivalent ie. NONINVERTING<br /><br />Good luck finding one though as they seem to be no longer in production.Puzzlebunkerhttps://www.blogger.com/profile/03215057040146701658noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-35720394193199545992021-11-19T10:07:35.698+00:002021-11-19T10:07:35.698+00:00any Ideas about, when I touch the pcb board It get...any Ideas about, when I touch the pcb board It gets louder and works fine.

Flipped the IC knowing Only one half was in use and pedal is back up (no led easy fix.) I love this pedal. I honestly wouldnt call this a drone noise machine. Its a highly controllable wall of fuzz with some softer sounds and sputter. Fuzz factory covers a much larger range but something about the sound of this effect keeps me coming back.

That's what I did. Just make sure you have an extra row above the chip for the output capacitor. <br />The kit Great Destroyer only used the right side inputs because it was on a PCB and it was more convenient to.

One thing to try is grounding some of all of the unused pins of the chip. It seems to make things louder and more reactive, but it probably varies greatly between builds and chips (it's a stupid, unstable circuit). I have no idea if the originals grounded the pins, but I prefer them grounded. <br /><br />The other thing I found was the volume pot/capacitor placement on the great destroyer kits is different from the schematics you'll find, as well as this layout (they may have updated the schematic for the kits, thus making it TGD version 2.1, or just as likely, the schematics were wrong). <br /><br />Basically, you remove the center capacitor (going to the output wire) un-link Volume 3 and Tone 1, and put a 1uf cap between Volume 3 and Tone 1 (polarity didn't change the sound, but I put negative leg to the volume lug). <br /><br />Then, you remove the Volume 2 wire and the old output wire and rewire Volume 2 straight to the footswitch. The kits also use a 10K resistor, but the trimpot is definitely the best option. All caps are 1uf, and orientation kinda matters (see my 2014 post) The circuit now should match the kit/newer circuit.

Your mod sounds awesome, i've always thought that the pedal could be tweaked a bit. How hard would it be for me to try and build a second one of these, with your tweaks, keeping in my that I have only a little understanding of what you are explaining. I've only built a few pedals (from kits) so I have almost no true understanding of the process.

It's a effin mess for sure but that's surely the point. There's a ton of stuff to be got out of it and it varies loads with very minor adjustments. There are definitely settings that seem to be offlimmits if you want to avoid bleedthrough even if it's turned off. But my wiring might not be totally right. I used 2.2uf caps in place of the 100nf and a 50k trim pot. No other changes. Also I have an sg type guitar with 50's wiring with alpha pots all round and it does "clean" up very effectively on some settings whilst still giving some rough and tumble tone that I very much like myself. I've found also that it behaves much better when fully boxed up, the grounding being kind of crucial. I reckon there must be some cap that can be put in somehow to stop the bleedback but need to work on that. 0friendsrecordingshttps://www.blogger.com/profile/17354056201651891355noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-62246956688729020882018-02-25T19:49:28.303+00:002018-02-25T19:49:28.303+00:00Can I add an MPSA18 transistor to the circuit for ...Can I add an MPSA18 transistor to the circuit for extra gain?<br />Anonymoushttps://www.blogger.com/profile/14082157511731462019noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-11193747678870194732018-02-10T09:12:34.190+00:002018-02-10T09:12:34.190+00:00suena muy bajo y las perillas no son muy lineales...suena muy bajo y las perillas no son muy lineales, pero esta bien para jugar y hacer ruido graciastxehttps://www.blogger.com/profile/12125478250661877524noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-30249639525906238272017-11-01T01:28:50.878+00:002017-11-01T01:28:50.878+00:00I used this one:
