If you're ok with using a PC (Win/Linux) you *cannot* beat an Analog Discovery Diglient USB scope. Function Generator, Scope, Frequency Response, spectrum analyizer, impedance, transistor, scripting, python support, etc, etc. Amazing tool. You can get a used one on ebay for less than $200...

Well when you have a defunct RD lab from the 80s-90s and there are THOUSANDS (hundreds and hundreds of boxes of 100s) in cabinets all over gathering dust...... sometimes you dont get all the values, but there are a lot of em. seems a shame that they wind up in a landfill somewhere. I've seen...

You "can* mount it off board and it will fit https://forum.pedalpcb.com/threads/my-atomic-doucast-with-1590bb-off-board-transformer-mounting.3013/#post-24329 https://forum.pedalpcb.com/attachments/dc1-jpg.4325/

I think I posted some of this before - but I'm still confused about "output" stages in pedals. I assume most pedals are "designed" to work with guitar inputs on amps. So the amp typically has a high impedance 1meg etc right? But if you want to plug a pedal into a "line level" (either +4dBu...

Anyone have one of these boxes? Would love to see inside or a schematic. Could make a cool pedal - hint hint....

I pretty much stopped after the Simulcast and then built the Duocast - love em.

I'll take a look - I do have OP07's

Yeah, I have a bunch of these. They just dont work with way pedal are powered. Too bad too - nice plugs and mount from the inside.

No problem - just pm your address and I'll throw a few in the mail.

Are you in the US? I have a few and can send you one if you want

Only thing I've ever done is adjust to taste - I always socket my LED resistors to be able to adjust. Seems like a lot of electronics manufactures dont bother and just try to go by specs - and wind up with LEDs that have the brigntness of a laser and could be seen from the moon. Yeah, MXR...

yeah I think I'll just try the way you suggested (same as mine). I'm not interested in all the options like the CherryPie. Just to get a "noramal tremolo" as an option would be nice. Whats also nice about this option is that if I socket C2 and C3 its super simple to try it out and hear how it...

Got it - like pedalPCB said just put the LEDs for the LDR's in phase. Or the way I had drawn out seems workable.

Did a search for the schematic but nothing turning up.

Right - I just put a 10pF so there was "something" there vs open to avoid pops, but thats pretty much what I'm thinking C2 is C7 in my schematic and C3 is C5

So a harmonic tremolo has a High Pass and Low Pass section. Each with a LDR (not sown in circuit). Can you get a "normal" tremolo sound by only using one of the paths and opening up the filter? Something like below where you switch C7 and C5 so they are either "off" (as shown = normal...

Great - I'll screen a few of the LDRs to taste. I take it you just used the 3mm tayda diffuse LED (as specified on the build doc)? Covered or uncovered? I looked at a lot of the harmonic tremolo projects / pcbs etc. The Pendulum looks like a great balance: not too complicated (three knobs)...

I thought the C100K vs 50K was supposed to give you more "low speed" range - I too wouldn't care for the super fast range Volume - not sure. The two reviews on the Pendulum seem to contradict whether the vol range is too much (high) or just right btw - anyone know if the KE-10720 (tayda) work...

found a cool link with PedalPCB Pendulum Zepplin Labs Quaverato BYOC Brown Face Harmonic Tremolo 1776 Effects Carindal Tremolo V2 Surfy Industries SurfyTrem I think the pendulum sounded awesome! Going to order one and give it a try. Opinions on the mods from anyone?: replace C50 with...

Go the bug for a tremolo... I don't have a harmonic trem, does the Pendulum sound anything like the Supro?
