I found a schematic claiming to be the Bogner Uberschall, and converted it to a pedal using Jfets. I used Gaussmarkovs Dr Boogey Eagle files and changed it to work for this schematic (so I have the Eagle files if anyone wants them?).

Please look this over and let me know if you think this looks correct? Also curious to hear your breakdown of this circuit. The presence control is the Dr Boogey layout. I left it in the schematic, and was not on the Uberschall schematic.

What was wrong with your old thread?

Like I said before, it'll make a high gain distortion but you'll only find out how much it sounds like an Uberschall if you build it.
Bringing you yesterday's technology tomorrow.

Yeah it is the same tread, but I didn't get any responces. I thought maybe it was the subject line not being to descriptive. So I thought I would try a new one with a more descriptive subject line.

I do not know much about how tube stages work, and I thought that someone that does might be able to glance over the schematic and say looks like it would work, or there is something wrong here.

Thanks
