Hi guys. Do you have some demos of this pedal, looking at the circuit i think it's going to sound great, and i need a replacement for a boss superphaser i'm using, to have my entire gig pedalboard diy, and true bypassed. Also...did you used matched ldrs?. How did u matched them?. 5 or 10 mm ones?. And what about the leds?. Red? green?, high bright? (transparent ones). Thanks a lot for any info.
By the way...in case MikeB is around here...your fxs rocks!!!. Don't get mad about envious people talking sh*t about nothing but a great design. ( tremulus thread). This is a great forum and i'm really proud people like you are hungin' around. Thanks for everything!!.

Was the Lune a design by Mike? I thought maybe it was a Dann Greene. Well the Fleur is a dann pedal anyways.

I didn't use matched LDRs. Just the ones listed in the parts list at Commonsound. Ordered um from Mouser. The LEDs were just standard Red rectangle so that they fit between two LDRs. Works great!

You know, maybe matching the LDRs would be a good idea. My phase is a bit lopsided. I think I'll redo it in a while....

Yeah, the tremulus isn't mine, Dann Green of 4ms did that one years ago .... the point was that the opinion posted on HC could well have dissuaded people from making the tremulus themselves or buying it from 4ms / commonsound. Moreoever, there was no backup of evidence, and the person who wrote that has bailed out of even proving their 'improved' schematic. To me, at least, it then seems they were making such statements out of ignorance and just simply to grand-stand. It's just one reason I don't post at HC.

Anyway, like Michael said ... use rectangular LEDs. Hmmm ... the LDRs I buy always have very similar specs as they are the same model. Another thing to do is to put a 100k -> 470k (experiment) resistor in paralle with each LDR to restrict the range, and hence also reduce the effects of any mismatching. Most LDR-based phasers (eg Mutron Biphase, infinitphase) have this resistor in there.

Sorry for what might be a dumb question, but I don't know if it's been covered - how do you guys match your LDR's?

I have taken two and measured the resistance when they're under the same amount of light - somewhat dim ambient light, dark, and then finally bright when they're taped up to the LED as verification. I haven't worried about it too much, but is there something else I should test?

The phaseur was one of the first pedals I built, and I too just used the LDR suggestion on the parts list. It's a CdS photocell out of the mouser catalog, part no. 338-54C348

Speaking of LDRs, does anyone know of a good place to order them? We saw a cheap Vactrols source a couple weeks ago, but some google searching I just did didn't yield too much that's cheaper than what I got from mouser ($1.10 a piece or so). Jameco has a grab-bag of 100 for $12, but they're as-is and random stock.

... is what I used in the phasur. I just use the LDRs as they come - I know there is *some* variability, but the phasers always sound fine to my ears (admittedly most phasers I build have the parallel resistor tho').

Mike

well, thank you guys!! . I'll go for it right now. Thanks again.
