You would wire it up like this (looking at the lugs of the 4PDT foot-switch):
This is how I've numbered the Potentiometer Lugs:

Re: death by audio dba reverberation machine gut shots and d
Here you go: https://i.imgur.com/vkeHSkr.png Couldn't figure out how to make the image smaller in the post so there's the link to it instead. I've added POT lug numbers. Hopefully that makes it easier if you are used to wiring diagrams (I prefer schematics). To have a LED indicator and all three pot...

Re: death by audio dba reverberation machine gut shots and d
That's certainly possible. Would you like to toggle all the pots or just one of them? Looking at it now it should be possible to toggle all three at the same time with a 3pdt. I could draw up a dirty sketch for you if you like.

Re: death by audio dba reverberation machine gut shots and d
Well I've never had any issues with this and this is pretty standard practice used in numerous effect pedals. Could you show a example circuit where a buffered reference voltage would be problematic? I've never heard about this issue before, and I'm interested understanding it. I,m no electrical eng...

Re: death by audio dba reverberation machine gut shots and d
Is this a reply to my post? Maybe you misunderstood my drawing? A buffered reference voltage is pretty normal stuff, and quite stable as the reference voltage buffer has a very low impedance.

Re: death by audio dba reverberation machine gut shots and d
if you have any specific refinements or ideas for improvements for the pedal i would definitely be interested in reading about them You could do the biasing similar to this: https://i.imgur.com/MeGfYv0.png Read about using a common reference voltage here: http://www.muzique.com/lab/buffers.htm I do...

Re: death by audio dba reverberation machine gut shots and d
yes. Taking their design-finesse into account, DBA pedals are way overpriced. On the other hand they come with a lifetime warranty, which is very admirably.
Biasing the way they do in this pedal would only add internal noise to the audio. Won't shape the (desired) sound in any way I can see

Re: death by audio dba reverberation machine gut shots and d
Is it just me are DBA kinda bad at circuit design? Why not make a buffered, less noisy reference voltage with the spare opamp instead of individual voltage dividers for each opamp? It would even require less components. This looks like a Also whats up with the volume pot?

you could try a cap to ground from the NPN base. That should give you a post-distortion LPF

Re: Malekko Vibrato
caps in parallel add the individual capacitances. Try another 2.2u in parallel Im thinking that would half the rate?

Re: Malekko Vibrato
Did you try increasing the Rate pot value? Or maybe substitute the 2.2u Tantalum capacitor in the LFO section.

Re: Fairfield Circuitry - The Barbershop (gut) [traced]
Read the thread. You can use a series diode instead of Q4, D1, R10, R11.

Re: LAL - Oscillo Fuzz (Lastgasp Art Laboratories) [traced]
is the 1N771A really necessary? It looks to me like its only a part of the ON/OFF indicator LED. Wouldn't removing the component all together give the same result in lighting and sound?
