Re: EBS - Multicomp [schematic]
Sorry for the double post but, I fixed it... I tried to replace the switch and didn't work, replaced it by a jumper and didn't work also. The jumper was shorting a via hole. Now it's working. I hope you like the pictures, let me know if you need something from the pedal while I still got it!. :mrgr...

Robert, why use the bipolar supply only for the output buffers and not for all the circuit, final clean headroom?

Re: EHX Pitch Fork
Thanks LaceSensor!, it's a little bit smaller than the DSP used in the larger EHX pedals (BF531 Blakfin series as well). Thanks!.

Re: MOOG Moogerfooger MF-103 12-Stage Phaser [schematic]
Hello, I've checked the schematic and found it is ok up to a small detail concerning the connections to the "positive" VCA output. RN3-2 should be connected to RN3-3 and PIN 3 of U10A what is the positive input VCA. In the schematic RN3-2 is connected RN3-3 and R34 and so we short input a...

Re: MXR Ten Band EQ M-108 new version schematic [schematic]
The dumb question of the day: There is a technical basis to use all these fixed 470 resistors and vary only the remaining components in each gyrator or just a designer choice? I mean, you could also set one value for all the bias resistors and so the other being those to be adjusted to the needs of...

Re: Z.Cat Poly-Octaver Chorus
From your pictures I traced out the circuit , it's a very basic FV-1 schematic. I have done quite a bit of FV-1 development myself over the last few years. From the pictures I see Z-cat has an input buffer which feeds both inputs 1 and 2 of the Fv-1, while the signal to input 2 is direct the signal...

You guys are the best! I can't wait to build one :applause: So how long do you think is it going to take for Joyo to clone one based on your schematics?

Re: MI Audio - Tube Zone 6-Knob Version [Schematic]
Finished up wiring my clone as close as possible to the real one and there's still something missing. The only thing seems remotely significant is that the real one uses polarized tantalum caps for the .1uF's and I'm using regular polyester (Cornell-Dubelier). Mine is noisier, but the big differenc...

Re: Wampler - Black 65 - FET bias opints [traced]
OK - here are the bias points: First FET - 4.08V at the drain. Second FET 4.00V Third FET - 3.95V Last FET - 3.93V VCC set at precisely 9.00V. Doesn't look like either hand picked/matched set or really good bias point - I'd bias them for 5V @ drain so I get more dynamic range before clipping but I ...

Re: Catalinbread Galileo Vox in a Box [traced]
Great!!!. All the Catalinbread's PCB layouts looks to me like they're made in a rush on half hour... . The pedal looks promising on the videos!, they said that is a CB30 and a Naga Viper tuned to work well togheter.

I think that Wampler matches the FET's, i'll be nice to get them measured to be sure, and the bias voltages.
Thanks!!
