ok well here goes
the vibrato controls are located on the left half, fuzz on the right
s-switch, k-knob

vibrato is a boss vb-2 clone (BYOC kit) modded.  controls include:
RAMP - on/off , rise time [k], momentary , external momentary jack
CLOCK - underclock [k], underclock fine tune [k], intensity , warble [3 s] in varying depths, photo-eye, photo-eye on/off
CHORUS - on/off , blend [k]
CAPS - 2 rotary switches to switch oscillator cap sizes [2 k]
SAG - on/off , volts [k]
FILTER - on/off , presence [k], tone [k]
INPUT CLIPPING
VIBRATO - depth [k], speed [k]
TRUE BYPASS ON/OFF

fuzz is a maestro fz-1 with one EH LPB-2 pre-circuit and one EH LPB-2 post-circuit.  all DIY
GAIN - pre [k], post [k]
TONE [k]
FUZZ - tone , balance [k], amount [k]
SAG - on/off , volts [k]
TRANSISTORS - choose old/new [2 s]
DIODES - blend [k], intensity , tone
TRUE BYPASS ON/OFF

so....19 switches (one is not in the pic i added it later) 18 knobs!
LOL i think i have a problem  :lol:

i also just realized that i bought your max/msp shirt and also wires shirt!
they're great.

yeah sag=starve
i do like the word starve a bit more, though...
the clock warble is 3 different caps (kind of like your high/low switch i imagine) that make the vibrato really warbly when it's underclocked a bit...also, i can switch all 3 in parallel so there's quite a few sonic possibilities.  i was thinking about adding a fb loop, but i'm not sure i can fit another knob/switch on there!

right. nice work, i think we are both on the same page. when i bend stuff for myself i usually go overboard and exhaust every option but i had to cut back for the downgrade to what made sense for the average joe, and kept it easier to build 10 of.

I've bought all the parts today except one, the ad781 IC. I did the analog.com sample thing so I guess I can only wait.

para-
how did you wire the bypass switch and the starve knob?  is starve in the 9v- of both batteries?

the bypass was odd because its bipolar so instead of using switching jacks and other shit i have the + of each battery on two of the poles of the 3dpt and then the + of the audio input goes straight to the center of the third pole and then one side goes to the board's audio in and the other to the out jack. notice its not true bypass because of this. if anyone has any better ideas please chime in. the led is straight from the + behind a 4.7 res then to ground just on the main board.

and the starve is only on the – battery. by the i mean the battery that is running as a negative supply ( with it’s + to ground ) and it doesn't matter if its the - or + of that battery.


funny, i'm just finishing my last board right now.

does that help? if you don't have a 3pdt then you can do it all with single switches too

the pink and blue are great!  the drawing does help a bit, although again the wording is a little strange...is the bottom left lug connected to two things?  sorry for the trouble... :/   i'm figuring it out...

You have mad crazy design skills man.  I sent the musictechnology majors your site, because they are all MAX/MSP heads and you have that new shirt.    These pedals are hawtt.  I wonder if bug's circuit could be tweaked for single 9V operation...  Do you get any switch popping when you switch the batteries like that?
