DOD Buzz Box PCB

rove · February 14, 2009, 11:41:15 AM

Hi, I was wondering if anyone here has made a pcb for the DOD Buzz Box. Not to be confused with the buzz box that is 2 bazz fuss boxes together, this is the "nasty" sounding pedal that DOD made for Buzz from the melvins (that apparently he didn't even like!).

Any help is much appreciated.
thanks,
Paul

oh yeah he didn't like it

But you can find the schematic I thanks, maybe I've it.

I have a PCB layout for it somewhere, I'll try find it for you.

the schematic is linked in my first post. A pcb layout would be awesome if you can come up with it, it's beyond my skill level to create it.
thanks!

I just noticed the layout I have is the same as the one in your first post, its the original PCB not a diy layout.

I just added the factory schematic (FX33sch.pdf) to that directory. I never compared it with Celadine's "Leafblower" trace.

I did build one without the distortion part and added another 4013. Plug in, send signal to jack and to octave bit. Input jack to mix pot. Sort of an "add you own fuzz to the buzz" notion. Could not get the fuzz to mix with the octave worth a crap. The thought that eventually I'd get something resembling the "Buzz" was too depressing to pursue.

Good luck!

Did you try mixing other divisions in? 4 of the 4013 flip flops divide the signal by 16, which mixed with the original may just make a weird muddy sound. Also, the signal off the 4013 is relatively high, around +/-3V after DC removal. Attenuating the 4013 signal before mixing and using one of the earlier divisions may make it sound 'better'.

Hi!

I did use a switch to pick one, two, three, or four 4013 sections. Four really wasn't all that bad.

I gave the prototype away. I'll mention your suggestion to the poor slob who has it now. Actually, he is the owner of the buzz you traced.
