mid-fi clai(not) schematic!

Warning, board spamming in progress.

If anyone wants a board for the Clarinot Cubed I can make them for $13 shipped US.
For overseas $14. basicaudiowv AT yahoo dot com
Rick, I assume this is ok with you. If not then lemme know.

what about asking me??

...layout on page 12 of this thread? If so, is everything working as expected? And can we call it verified?

Finally found the problem with mine- microscopic solder bridge, of course, that took forever to find.  Also, I was trying to use a blue superbright LED- switched it back to the pink one I used before & everything is hunky dory (forward voltage requirement of blue too high? Hmmmm...) Anyway, Rick, I call yer layout verified because I am now achieving mucho groovy weirdness.  Kudos, man.

Fantastic device, wonderful sounds, ingenious design!
Has anybody tried it with 12 or 15 or 18 Volts power supply to get more headroom for clean sound ?

Hello, I was looking at this layout for this pedal and was wondering what the bent line with the arrow means on all the pots, is that just the symbol thats being used for a pot or does it mean something?  Sorry im new to this and ive never seen it before.

[quackenbush]

yeah, that's one of the symbols for potentiometers. electrical engineers are just as bad as classical guitarists are with developing multiple redundant notations for things.

also, first post, Hi everybody.

Hi men,
Has somebody tried expression pedal with 100 kOhm pot in place of internal 100 kOhm "Delay" pot?

Hey, after all the talk a few years ago about the fuzz lift switch...

The LED didnt light cos the signal was too weak. But couldnt you just tweak the values around the led/ldr to make it work?

Sorry I didn't see this earlier, but I did in fact put an expression pedal on the delay pot and it is awesome.  Highly recommended.

I used a 2k pot for tracking and never had a problem with the fuzz lift canceling out the tracking effect.  If you don't have a 2k pot you could try increasing the value of R8 and see if that does the trick.  BTW, I was using a VTL5C2 as the LED/LDR, which will affect the response.

Or you could add a buffer at the beginning of the circuit, split the signal, one half goes to the delay chip, one half goes to the 386/led.

I may have heard this a version that does this recently. 

[El Heisenberg]

Whats up with all the winky faces? Lemme in on the joke

[doug deeper]

I have a new version of the clari(not) that is fuzzless.
That's how you do it! 

[El Heisenberg]

Um is there a schem out?

How is the LED lightig up if youre bypassinf the 386/LDR?

Doug builds these and other pedals to make a living. Don't expect him to reveal his new design immediately!

From two posts above yours, with no mention of bypassing:

[El Heisenberg]

Oh jeez i didnt notice i was talking to the designer!


I guess ill just haff ta breadboard it and mess around.

[p_wats]

Is it weird then that my build works really well with the fuzz-lift as is? I rarely ever use the fuzz at all and still get all the weirdness I want.

Probably depends on the brightness of your LED and the sensitivity of your LDR.

But I'm guessing Doug's new design still uses a 386 to active the LED, it's just not used in the audio path.

Thanks. I don't recall being too picky about the vactrol I used, so I guess I got lucky! Ha.

Yep!
The buffer is a jfet, 10k resistor, and 2 10uf caps n the output.
The audio side goes through a 15k resistor to the junction on the 10k and 22k that feed the delay chip.
The other half goes from the second 10uf to the input of the 386, everthing is the same there except the .01ufcap and the 100k resistor are no longer there (so the fuzz doesn't get to the delay chip).

[El Heisenberg]

JEEZ!

I was going to experiment! I was looking forward to doing it wrong lol!

I sorta made a wild guess that you used an op amp and I was gunna be all clever and use a JFET. Blah. Can't beleive you just give away the idea. Nodody better be selling clones da*^it
