That Orange Squeezer is really nice Mike, where do you get that acrylic (perspex) from ?

Anyone can share the size of the Arcrylic cut out for 1590A and 1590B enclosure?

This may have been discussed but I couldn't see it.

If I wanted the boarder to light up with the clipping on a distortion/overdrive build I assume I could just put one of the LEDs from the clipping section into the plexiglass, but what about typical silicon diodes?

I would kind of like how it to go bright and slowly dim as the notes decayed.

If you had an extra op amp section I'd put a peak follower on it with a cap large enough to extend it out and then drive it from the input.  But I don't know... do LEDs in clipping circuits flash?

They do in my CJOD but I've read they don't always flash. I think it'd be interesting to have them light up because when I watch them in the overdrive they go from bright and slowly decay down. But not real bright

Take a look at deadastronaut's 'sound to light' circuit. It isn't exactly the clipping LEDs lighting up, but it seems like it would be perfect for what you want.

Be aware that if you allow ambient to hit a clipping diode, it will modulate the signal,  If the light source happens to be noisy, like a fluorescent, that will be superimposed on the signal.  We once made an experimental touch panel using LED emitters and LED's as photodiodes and we found that the leakage current in LED's exposed to light was rather high but the concept worked - just not well enough for our purpose (which was to design an optical touch panel operating in the green where it would not be as affected by ambient light as one operating in the infrared), because the leakage doubles for every 10°C rise in temperature and it was a bit marginal at room ambient.

Is there a way to feed of the clipping diodes without harming their function?

To somehow have them drive another led?

you could always shine the clipper leds at an ldr in an opamp feedback path, you might work it to drive indicating leds.

I am sure you guys have seen these? You can put a 3mm LED in the backside and the shaft lights up.. use clear knobs etc..

Thanks guys for this cool mod! Had to mod my wah pedal  :)

Used 4 LEDs, 1 in the middle of each side. First time I failed with 3mm red LEDs, very weak light. Next time I used 5mm clear red LEDs (Tayda: LED 5mm Red Water Clear Ultra Bright, SKU: A-706), used sandpaper on them and finally satysfying result  :icon_twisted: It doesn't look effective on photo, but it is quite strong in real life.

Now you need a stacked pot....Why??

To control the brightness of the LEDs as you press up and down on the treadle.  :icon_mrgreen: :icon_twisted:

This can be done with the scratchless opto wah conversion.  In my build I choose to have just one indicator led that varies brightness with the pedal movement.  More subtle as is my taste.  Still used the lighted base plate for on off indicator function.  I may have the highest current draw of any wah pedal in the world! Lot's of LEDs in there.   haha

so once you've got the treadle connected to a voltage divider, there is nothing except good taste preventing you from adding an LM3915 or 6 and a stack of leds, so the whole thing gets brighter or differently coloured or progresses around the treadle etc.

nothing, you hear?!
