VFE Old School Tremolo

Original Info:
"Our OLD SCHOOL tremolo pedal recalls the luxurious tremolo sounds of vintage tube amps. Derived from a rich sounding, but feature-limited tremolo circuit from the 1960s, we added extra range to both speed & depth controls. But we did not stop there! We added two unique circuits - one to starve the circuit to add grit & chop, and another that can adjust the speed or depth based on your playing dynamics."

You can find Madbean's PDF with schematic here.

    Nice one, I was seriously about to make a layout for this one in the next day or 2.

    Call it verified! Sounds and works exactly as it should. Used a NSL-32 since i have some. Reckon you could do this with a diy LED/LDR but didn't try that. Thanks as always Alex for the layout.

      Looks like the NSL-32SR3 is higher spec than the regular NSL-32, but I don't have an SR3. I'll give it a go with the regular one. The SR3 datasheet says 25MΩ to 150Ω compared to 500kΩ to 500Ω so I'm guessing I'll loose some depth to the tremelo?

    Thanks for the layout!
    I found in this page some optocoupler, two of them are NSL-32. I'm a bit confused about the right one.

      Thank you, and forgive me, I forgot the link of the page:
      https://www.musikding.de/navi.php?qs=nsl

      Anyway you can see the names in the details of the two products: NSL-32 and NSL-32R3. This make me confused.

      I think it's the 3.90€'s one.
      Banzai Music has it.

      Waiting for clarification here. Built it with the 49 cuts and it didn’t work first go, but it could always be me.

    Hello, love your site,
    So if I wanted to add a foot treadle like the univibe, would I just remove the speed pot and add a jack for an expression pedal? Since the pot only has two connections, I'd use a TS Cable and not a TRS. Maybe I'll try and find a broken wah and just build it to fit in that. Thanks and keep up the great work. Regards C

    How do you wire up the switch for this? Since Led- is at board standard offboard wiring dosnt work.

    Built this up last night. Many dumb mistakes were made, but it works well and is a very fun, useful circuit (less quirky than the Blue Warbler, which is also fun in a similar way). Thanks for posting the layout!

      I should mention I only had a standard NSL-32 and it still seems to work well. Though I'm curious how an NSL-32SR3 would affect the reactive time of the envelope, so I may try to get a hold of one
