ok, salvaged a 10k audio pot for the hi pass and it's all as it should be now.
currently playing around with that 39uf cap spot with leads running to a bread board. 10uf, 47uf and 100uf all sound great respectively, even went as low as 4.7uf and it is super snappy. I can't decide!
considering a 3p4t rotary switch to have them all. why not?

sorry about your snow.

[MAO]

Cool, no doubt I'll be adding a "decay" switch to mine.

I tried both Tayda LDRs and 5516s, neither really cut it regardless of LED color/type. I don't think these LDRs light resistance is low enough for this application.

I suggest sticking with the NSL-32 (specs seem identical to the original CLM6000s that Craig had used)

[clockman]

Thanx for giving those ldrs a test. I have yet to order the nsl32, currently looking at smallbear's selection of ldr as well for a couple other projects.
I'm actually impressed by how it sounds with the tayda ldr so can't wait to hear the proper ones.
Did you get a chance to play around with the decay switch idea? I'm loving 10uf and 47uf.

[MAO]

Sorry, haven't tried the decay caps yet, been finishing up a couple other pedals and trying to get the Anderton Phase Shifter more to my liking.

Any chance you can record a clip with the Tayda LDRs?

I'd like to hear how yours compares to mine.

Hello

I built it today (using the tagboardeffect layout i found first) : it sounds gorgeous !

Everything works fine and as expected, except that, like Muadzin wrote above, " Lo/Hi switch causes oscillation (a hi pitched whine) when I turn it on".
Muadzin, did you manage to fix it ?

Hey MAO, any idea as to how can I adapt the envelope follower to make a Slow Gear type effect?

[MAO]

I'm not familiar with the Slow Gear, I'll check it out and get back to you asap.

I have been recently using the envelope control from the VFE old school trem on phasers, chorus, flangers etc. Mostly on their speed, intensity and/or depth controls. Works well.

 Hi MAO, funny I was just singing praise to you about this device in another post recently in the requests section. I'll do it " in person" now. Thanks again. this build inspired me to experiment a bit and has led to untold hours of enjoyment.

 I mentioned that I had built the envelope follower board (with slight modifications) into a stand alone device to control other pedals. It works well. Highly recommend it on Escebedo's ugly face fuzz and PWM fuzz.

 That being said, by far the most tweak-able envelope control set I've come across yet belongs to Chunk System's Agent 00Funk.
 I'm currently "stealing" voltage from that pedal to use on other pedals. I just tapped into where the internal LED  and parallel wired a jack out. not elegant but very functional. check into it if you want a great control set.

 I'm going to have to try the VFE now.

The Old School has an envelope?

[MAO]

Thanks for the kind works Clockman!

I should say, the VFE responds differently than the Anderton EF. Checkout a couple of the Old School Trem videos to be sure it will work for you.

I haven't tried to modify the Old School EF, I've been using it just like he does. But Im sure it can be tweaked to adjust the attack and/or release time.

I have a layout for just the EF portion if you want to give it a try.

[MAO]

Yes, it's engaged with the switch. Controlling either the speed or depth.

I did draw a layout for just the EF section, let me know of you want to try it.

[GrooveChampion]

Well here's the deal, I want it to auto swell like the Boss Slow Gear, or the Paia Gator, problem is I have no idea how to make that

[clockman]

I would love to see that layout.

Can't believe I didn't know about the Boss Slow Gear before today!

Don't quite understand how that one actually works at the moment.

Maybe Madbean's Rust Bucket 2019 will get you that swell?

[GrooveChampion]

Yeah, that's the deal, I am looking for something smaller and simpler. Something to rival the attack part of a POG2 or the likes.

Though I guess a good place to start is basically with this:
