i have come up with an idea for a pedal, not sure if it will work or not.

using one half of this diagram http://www.beavisaudio.com/Projects/ArmageddonProcessor/index.7.jpg i plan to make an effect which feeds into my guitars signal when guitar goes into the amp. (so it mixes similar to on the zvex, think muse - plug in baby i think)

fro this i would mouont said circuit into an enclosure similar to this http://www.smallbearelec.com/Detail.bok?no=548 but i would like to know if i could buy a similar enclosure, to control pitch via the foot in a volume pedal, wah pedal style. preferably in england, and preferably cheaper.

would this work?

and how would i connect it to toher effects, i'm thinking have a guitar input and output on the pedal, a true bypass switch for mixed and unmixed, and a volume for the added tones.

I did this exact thing with a DS-1. All you need are 2 wires and a SPST switch.

Link in a sec...

edit: Screw the link, here's a pic. Enjoy!

i'll pm you a paint pic of my plans might not work cos i cba to make an acount on photobucket or whatever

EDIT: take a look at these plans if my internet doesnt die on me, i really dont understand your post, i'm not lokking to mod anything

and another EDIT:

its this:

k, then.

first of all, the "oscillator" looks like something that will work.
as the pot (foot pedal) resistance is lowered, the frequency will increase.
basically a square wave coming out of that.
you have a voltage divider after it.
that's good, because the square wave is gonna be huge.
it will go from rail to rail.

but you have some big problems where the oscillator signal
and the guitar signal are mixed.

the guitar is not gonna like being loaded down by that circuit
when the switch connects the two.
and when the volume pot is set to zero,
that will completely short out the signal from the guitar.

add 2 opamps to this.
use opamps with jFET inputs.

one will be a buffer to provide a high impedance load on the guitar
but will output a low impedance to the mixer.

the other opamp will be your mixer.
two separate input resistors.
one connected to the wiper of the volume pot
the other to the output of the guitar signal buffer.

both the buffer and the mixer should be designed for low gain.
unity gain, or maybe a gain of 2 should be fine.
