That was my first impression, this seem to be impossible to be repaired.

Hello, A friend of mine came with that pedal, it stopped working and he wanted me to have a look and repair it, I I corroborated that it does not work, but what a surprise I found when I removed the cover, I asked him how musch did it cost ans he answer that he paid 100 eur for this: https://img.pho...

Which pot of the comercial ones to use that fits a "dunlop" shell?

Please let's make a short revision for anyone interested into get the working point of a voltage divider biased transistor: a) Vb = VccR2/R1+R2 b) Ie = (Vb - Vbe)/Re = Ic ; Vbe is tipically 0,3v for a Ge trany c) Vc = Vcc - IcRc If R1 = 470K, R2 = 68K, Rc = 10K and Re = 3K9 then: Vc = - 6.85 --> GOT...

It's a start. I would add an adjustable LPF on the output of it. This should be an active filter with a steep rolloff. To get the "organ" sounds you need to be able to mix in the octaves and then roll off the high-freq with an LPF. Then, make it controllable from an expression pedal as an...

I can't access to the photobucket url of the schematic file.

anyway thanks for the job markm

Well, here is my proposal for an analog POG, feel free to contribute, discuss, argue, what would you add? ......... please!

OK, I need 5 post to link an url

Thanks dajm!

Hello,

I personally love the "organ like" effect that can be obtained from the POG, perhaps could be interesting to discuss about the possibility of designing a non based DSP POG (complete analog device) starting from block diagrams.

What type of effect is in fact?

Thanks in advance.
