mid-fi clai(not) schematic!

well,
looks like those other guys have reversed this one, so you guys might as well have the schematic!
(ive put it in my photobucket as i dont think links to that site work?)

enjoy!

Shame it's been reversed, but I think it's a great gesture sharing it here

It's got to be one of the most amazing pedals I've ever heard, I can't believe the schematic is so simple, it's a really elegant design.

why thank you!

So the signal strength modulates the delay time which creates the pitch-shifting?
How does the blend work out: Blend between fuzz sound and pitch-shifted/delay-modulated sound?

Sounds insane! I like it.

killer design !!

Dude.

Sick.

yeah, it blends between dry fuzz, and shifted fuzz.
it can do flange-ish things on certain settings too.

A true gem amid a sea of sameness. Thanks for sharing, Doug!

[small design critique: it would be "nice" to include the RF filter on the output of the 386 (as shown in the datasheet), especially since the 2399's clock is so nearby.]

This has got to be, hands down, the coolest move ever. You rule, Doug. And the Clari(not) is pure, original genius in the midst of an entire industry predicated on hiding cloned classics behind black goop. Bravo, sir.

you should send one of these to Kawabata Makoto

thanks for sharign this! I'll definatelly experement!

naw!
all he needs is his trusty wah!

Is there a soundclip of this thing anywhere?

See the video.

wow.

orangetones · February 19, 2009, 11:14:13 PM

Sick...

That's all.... I just breadboarded this. Man can you get some wild sounds with this one. Would be really cool run into a delay with a feedback loop. Unfortunately I took the pt2399 out of my delay to build this!

jacobyjd · February 23, 2009, 10:14:27 PM

I just finished hand-drawing a vero layout for this, and I've learned some things:

1. I am apparently a masochist
2. I've got nothing on Cathexis
3. Making my own layouts makes me learn. You should try it too.

Can't wait to verify it in a few weeks (when I can afford another parts order

)

rousejeremy · March 20, 2009, 05:38:51 PM

Awesome. Love this pedal.

Can't wait to see the vero for this.

snufkin · March 20, 2009, 06:20:56 PM

WOW very cool

doug if I build this maybe can I pay pal you a few pounds?

doc_drop · March 22, 2009, 10:24:24 AM

Wow. I watched the videos, and I would love to build this thing. I was getting all ready to breadboard it when I came to the LED/LDR thing. Can anyone help to explain how that works, and what it is in the circuit for? I had to Google to find that and LDR is a Light Dependant Resisitor. O.K. so does it react to the LED? Anybody?

If I can't find an answer, maybe I will just breadbiard it without, and see what happens. Maybe even putting a pot in place of the LDR to see what effect it has. But I would rather understand what I am up to before I spend too much time...

slacker · March 22, 2009, 10:31:43 AM

It's pretty simple, the LED shines on the LDR and the LDRs resistance goes down as the brightness goes up. When you play the LED flashes, the harder you play the brighter it flashes and as the sound dies away it gets dimmer. The LDR controls the delay time, lower resistances give faster times.
