BBE Green Screamer

The Green Screamer is an overdrive pedal that produces a dynamic range of smooth and warm overdrive tones associated with vintage tube amps. Robust build quality and rugged engineering ensure that the Green Screamer will stand up to the abuse of life on the road. Other features include hardwire bypass, LED operation indicator, non-slip rubber bottom, easy-access 9v battery compartment and included external power supply.

  1. Verified, and can I add that this is the first circuit that has actually caused me bodily harm to verify. I managed to stand on an upturned IC that decided that the sole of my foot would work quite nicely as a socket. I'm surprised no-one heard me swearing.

    Anyway, back to the layout. It's quite a nice 60's/70's rock sounding OD, not bad for how easy it is to build. The drive pot wires are back to front though and if anyone is using an electrolytic cap for the 1uf negative goes to Vol 3.

  2. My buddy has an original. I modified it for him and it sounds awesome! I used a NE5532. He uses a power supply, so the 6mA draw was worth it. Also, I swapped the 100nF out and put in a 470nF in it's place for a bit more beef. Also, swapped one of the diodes to an LED for asymetrical clipping. That brightened it up and increased output, which kinda balanced back out with the 470nF cap. I like it. My suggestion on this build is to socket the diodes, and the 100nF cap so that you can play with the three. I saw a post somewhere that a guy used 1uF for the cap and thought it was too bassy, but the 0.1uf lost too much bass. That's why I went with the 470nF. Regards,

  3. Built this today. It's just a louder TS9/808. That really is all there is to say about it.

    1. And Madferret is right, the Gain pot needs flipping.

    2. 2k ou 2,2k peuvent faire l'affaire, sans problème.
