Black Cat OD-1

This one's pretty simple, but is really versatile going from light overdrive to fuzz levels of gain. Originals use an OP275, but other dual op amps can be used (1458, 4558, TL072, etc.). It's should be a nice fit in a 1590a.

    The four 100n should all be 47n. 10uf should be 22uf. Schematic that has been floating around the internet forever is wrong.

      Also seek out the correct IC - it makes a big difference in the circuit

      Why 47n instead of 100n? On EVERY other site there are 100n's.

    Milosz - trust me... I know very well what values are in this circuit.

    You can tag it verified! I used the 4558.

    I made it, but it was too loud for me. So I put a 47k resistor before the level pot. I think you should use a 50kA pot for the level pot.
