This is a fun one from the boys at Lectric-fx, the flyleaf. It's the Zipper envelope filter and it's got a different flavor. I've had this built and tested since early December and finally boxed it up, which is not like me since I generally start and finish before starting something new. An OTA lm324 and jfets replace the vactrols on something like the mutron III/Q-tron which give it grittier sound and lends itself better to more synthy type sounds. I like this one and am thinking of leaving it on an all bass board I'm working on. I especially like it in LP mode on the slow attack setting. Nice range on it too. Another winner. Tayda powder coated light blue enclosure with Quicksilver graphic. Nice easy build with good tones.

Fuckin tight
She's a beaut', Clark!
That's awesome!
This one went under my radar. I usually prefer OTA phasers over optical. Do you think their are tonal parallels between phasers and filters with respect to optical versus OTA?
Thanks guy. To answer your question John, the only other ota envelope filters I've played are the DOD fx25 and 440 reissue. It's a slightly different flavor than vactrol based ones but I generally tend to like most ota based pedals. This one I think has a more linear and consistent response to the envelope where as led/ldrs can vary quite a bit. It's smooth though. And I agree it's phasers are are supreme superiority.
I think you've mixed up the LM324 with the LM13600, there's no OTA here, just J-FET's as variable resistors.
Can't think of any other envelope filter that went that route off the top of my head.

Damn your right Scruffie, I don't know what I was thinking. Must have been just the DOD stuff then. I haven't read the build doc since last December so I don't know where my head is at! 🤦🤷 Post edited to reflect me being a dumbass.
