Here's the Odie from Run Off Groove. It's an alternative to the Tube Screamer using JFETs. Be sure to adjust the drain trimpots to 1/2 the supply voltage. Sound clips can be found
here.
This one is verified (and sounds fantastic). Here's a few pics of my build.
Ajust the trimpots to 4, 5v?
ReplyDeleteYeah start there, but tweak it by ear. I don't remember the voltages I ended up with in my build but it wasn't exactly 4.5v
DeletePlease... Gimme a sound sample of this one. Thanks brother, may you have a long life
ReplyDeleteoh crap..!! I didn't see "here" above.
Deletemy bad
done building this one.
ReplyDeletenice sounding OD
The transfer image in the library are missing some pads. 2 pads for Q3 and one for the 47uf cap. I drilled the holes anyway and I think it'll work just fine.
ReplyDeleteJust built this this weekend, yes the transfer library is missing some pads, same as Henrik found 2 pads for Q3 and one for the 47uf cap, but I drilled them out and it worked great. I did not have any 3.3nf so I used 4.7nf, and I accidentally swapped the 100K with the 250K at first , and I kinda liked the tone I got from that, I have not done the math yet to see where are the frequencies are at with the changes, but this pedal rocks!
ReplyDeleteAccording to the schematic there is a 1n capacitor after the 3k resistor. Is it not necessary?
