Taking a break from the Madbean bonanza since Chris Stelloh sent a layout and a schematic of one his creations. Some words from the man himself: And yes, this layout is verified.
Here is something I came up with recently that shakes the pillars of heaven, via WAY TOO MANY cuts and jumpers.
It
is essentially the modded fuzz face circuit from the Apocalypse Audio H
Fuzz with an input buffer (sacrelige, I know), followed by a 5 band
gyrator EQ. I used the values from the Dunwich Left Hand Path modded
HM-2 and added a 5th lower gyrator that centers at 60Hz, so that
bassists can bring the buzzsaw, too. The gain squeals when maxed, but
the gate will still clamp down on it nicely. The d311 germanium diode is
most likely not necessary. Anything with a .3v volt drop will probably
do the job. The 50k trimmer sets the treble content from the fuzz before
it hits the EQ stage and sounds best (to me) at about 1 o'clock, but to
each their own. This WILL fit in a 1590bb, but just barely!
