I understand that the Forest/Pale Green compressor schematics are similar, but we're not expecting them to be identical, are we?... I see that on the Forest/Pale schematics that there is a resistor and cap in parallel in this section, but I don't see that on the Warden's circuit board images.

Maybe it's these small details that set this pedal apart from its brothers.

Here you can find some suggestions of mmolteratx about how to modify a Pale Green to something like a EQD Warden: http://www.freestompboxes.org/viewtopic.php?f=7&t=16698&hilit=pale+green&start=40#p228040.

Here are another nice ideas from daimondamps: http://www.freestompboxes.org/viewtopic.php?f=7&t=10725&hilit=forest+green&start=120#p239960

If I remeber well, I took the output from C4/R6 junction and it sounded OK...no distortion...so, maybe something around IC1B could be wrong...in Pale Green there is no IC1B :)

Which is the role of IC1B? In my ignorant opinion, it only amplifies the compressed signal (taken after R6) mixed with some clean signal (taken after R12)...the ratio between clean and compressed signal seems to be 1:10...

Moreover, R12=10M seems to feed IC1A from the voltage divider R15/R16...but isn't too large? Have IC1A enough current ot this is the cause of distortion?

Sorry for my english and sorry for my poor electronics knowledges...all my thoughts are based on similarities with other effects that I have built :)

I did some experiments :
mounted a 78l05 to feed the Led circuit and works well, now the Led I think it's in the right range but I don't see it change the amount of light when I play.
Connected the release pot in parallel with C2, and I start to hear some compression but I can't tell if it's the rise of the amount of the distortion.

P.S. I have a lot of 1M resistors with the green band that seams blue.

everyone give up?

I tried the NSL-32 and the NSL-32SR3 with 25Mohm dark
and with the SR3 works better, less distorsion and more compression

Now, for something completely different:
I love the 125B layout of this pedal! Could someone measure the PCB dimensions and positions of the middle pin of each of those Alpha pots?
Just write down the H, W, A-F measures depicted here (the picture represents the pcb):

Thanks!

Hi guys.
The question is that I built, how the Attack and Release regulators work, do they ever sense on optical compressors with their slow Attack and Release?

I think the Resistor in parallel with C2 might be a 22k looking at the circuit board from the picture above that would put it in parallel with c2 and then run into the 4.7k/50k release controls into the cathode making the release pretty similar to most optical Compressor release controls I have seen

Has anyone gotten this to work? If so what circuit did you follow?
