Filters and other weird stuff

[Austin73]

Is anybody out there making anything weird. I'm looking to make something different than just fuzz pedals as soon as i work out why my Bazz Fuss don't work. lol

On a serious note has anybody got synths, filters etc projects that would be fun with the guitar. My main pedals I use at the moment are the EH Synth, Bass Balls and Line 6 Filter Pedal.

I know frostwave do some cool stuff and that the alpahwave is knocking about but I think it would be rude to ask these guys if I can have there schematic/pcb layout for nothing,.

Cheers for listening to me rant

i would like to start. i succesfully builded an inductor less wha and trying to connect it to a breadboarded lfo but i would like to make a kind of "modular" effect with more than an envelope, 1 lfo, and then wah, resonance and cutoff filters  etc. maybe patchable like a modular so you can connect everything with patch cables..

something like this:


ps does anyone already has an envelope follower layout or pcb ready?

See this?

It looks like its similar to the downsampling part of the Logic Bitcrusher plug in.  Stick it in a wah pedal or something.

Like ring modulators?

I'm currently working on improving this design--sorry it's not a ready-to-build project, but the schematic shown will work.  I have had a bit of a break from the analog recently as I got my PIC programmer last month and some uC chips and MPLAB and I've been doing some microcontroller hobbying recently (just finished a little RS-232 ASCII message formatting device).  Now that the RS232 project got me on my feet with the PICs, I've been working on a PIC based signal generator so I can get my sines, tri's and ramps out of an 8 pin chip instead of an analog circuit that takes up half my breadboard.  I think I'll also have a tap tempo LFO mode for it too...why the heck not?

Anyway, check out some of the noise makers like PWM and ugly face...i also have a schematic for the filter in the KORG Delta synth.  It's an OTA based filter that seems to have a nice sound.  The ADSR might be an interesting function to add to a guitar effect.
