Where do you make the LED pulse at the LFO rate on a small clone? I built one a week ago, and I'm trying to make it look a bit more fancy. I think it;s supposed to go on the LFO chip's pin 1, at least that's what I heard. Any suggestions?
Try an 'emitter follower' to avoid dragging the line down.
Small Clone? I've never seen a chorus with a rate LED....are you sure that's not Small stone?

I just finished a small clone last week and that is where i wired in a LED to get a blinking light that varied with the ,I hope this is the right term, oscillation. Just to pin #1 and grounded it. I also did all the mods as found on the Tone Pad site and this is an awesome chorus in my opinion.
Is it the LM358's pin1?
btw, what pot value for depth did you use if you did the depth mod?
Yes its pin 1 of the LM358. I used a 100k linear pot for the depth mod. If you haven't looked at tonepads build report for this one I would recommend it. There are a lot of good mod ideas in it.
I also built a tonepad one, but it says two different things! the old version says a 100K audio pot, the new one a 10K linear. I should use the 100K linear, I guess, eh?
I tried doing the LED blink, but it doesn't seem to work. The effect works though. Mind taking a picture??
Also, Do you have any problems with the small clone? (i.e. clock sound, etc)
No, you need the 10k one, the 100k was a typo or something. I assume you are talking about the depth mod?
I used a 100k linear and by using that the change in depth seems to be spread out along the travel of the pot pretty well. Its not just a big change on a 1/4 turn and then nothing on the rest is what I mean.
As for the blinking LED I just hooked the positve to pin 1 of the LM358 and the negative to ground and it worked fine. Unfortunately I do not have a camera to take a picture of it with.
As for any problems I have not found any. It seems to be a very well designed effect.
Hope this helps.
Hmm okay well I stand corrected for the depth pot mod. The schematic I printed from tone pad did say 100k though.
I know, I had the same schematic, but the maker of the schematic said it should be a 10k pot somewhere on this forum. It's pretty logical when you look at the schematic, 4k7 + 2k7 is much closer to 10k :)
analog mike uses 10k linear on his clone chorus, and the depth mod different and alot smoother.
Ok, good news. I got the LED working. Bad news is the depth pot STILL has the same problem. Where do the pins of the pot connect to the board? I think one goes to ground, 3 to the original switch hole, and 2 from the 39K resistor. Help, anyone?
I second this question, but for small stone. I wonder if its possible to get an effect not just on and off but in a pulsating way.
You have to locate LFO output and connect the LED (with CLR) to GND..
Depending on particular OTA current drive capability, you might (or not) need an Emitter follower to drive the LED..
