Lune vero question

Is this vero layout for the Lune verified? I checked it against the schematic, but I trust myself about as far as I can throw myself when it comes to these things...

Has anyone built a successful circuit from this layout? I tried to build this pedal last year from a different layout that only had 4 pots (can't remember it and can't find it now) that didn't work.
Thanks!

It works. I built one from that vero a few months ago.

Awesome! I'll build it right now, I think... report to come.

A couple more questions about that vero:
What is "S1"? Spacing?
With the note about S1, is that the rate indicator LED?
And what is D1 - k?

I too will be building this once I get my parts from Futurlec!!

Thanks.

Looking at the schematic, http://commonsound.org/tremulus/tremulusscheme.pdf it looks like that is all part of the 3pdt bypass, but that doesn't seem right to me. I can't figure out what R11 and R12 on the schematic are for.
D1 K is the cathode of the LED, I assume, the anode of which connects to S1 lug 2. But is S1 just the middle row of a 3pdt for bypass, or is it a separate switch? The schematic makes me think bypass, and the layout makes me think separate switch. Any thoughts?

I did find this that shows an interesting looking mod.

Adds a ramp up/ramp down.
Anyone tried it?

rousejeremy

I've done that mod to the vero above as well. :)
It's pretty cool and easy too. Only noticable on certain settings though.

I should be able to use a 5532 instead of a 4558 op amp, corrrect?

svstee

I believe so, but I think that the 5532 is more expensive and harder to find, why not use the common and cheap 4558 if that was what the circuit was built around? Just wondering.  ;)

Also, can someone explain to me if S1 is just the middle row of a 3pdt for bypass, or is it a separate switch? Still not sure on that...

rousejeremy

S1 connects to LED anode. The LED will flash at the rate of the LFO. You can run the cathode to the switch to use the LFO speed LED for a status LED as well. It's a cool effect.

Thanks, I actually already have some 5332s, but no 4558s  ;)

I'd like to know too. Is S1 the bypass, or does it switch something else? Usually on these kinds of layouts, it's up to you to add the bypass switch stuff.
