So it's safe to say that almost every BBD-based modulation effect is my 'nemesis circuit' NO matter how meticulous I've been in builds, or how much I've tried cramming related analog circuit engineering into my skull.

I've been reading about BF-2 substitutions, and if I read Mark's comments correctly, one can drop-in a xx3204, but that if the clock is running at the same rate you treat it as if you have half the stages of the xx3207. This results in a tighter effect for flangers especially.

My question is if this can be done for chorus effects, or if it would just be terrible sounding?

As long as it's pin and voltage compatible there's no harm in trying. At worst, it might be more boxy or metallic sounding than a typical bbd chorus.

Not sure what's happening there. It adds to cart fine on my end. Can anyone else check and see if they have the same issue? If so, let me know which browser (thanks in advance).

I'll PM you johnk.

Check for DC on the pot. It should be 0v on all three lugs but if not one of the 220n caps could be bad.

Any chance that Freekout is dropping soon?

Yeah. Docs are 99% done (for everything). Just waiting on the VFE MCU delivery which should come in the next couple of days.

I'm in hour 5 of the 2 hours I thought I needed. Still at it so no insults

You guys are being mean and I like it  

All the restocks have been inventoried. Just need about two more hours to finish up the new project docs tomorrow.

The VFE MCU have been delayed a couple weeks, no reason given. So, I'll just not worry about those and get everything else out.

BAT41 have a slightly higher forward voltage than 1n34a. You might try BAT46 instead.

Right around March 10th or sooner. I've also got restocks coming at the same time including all the VFE projects. There's another 10 or so projects that will drop soon after that, too.

Do you hear the relay click when you turn the effect on?

Hey guys, recently had a request from someone to add a rate LED to a Polytrog I build for them. I assume it will follow the "rate" pot if I put it in parallel with the LDR LEDs? If I do this, should I put it after all of the vactrol LEDs and then lower R42 to ~250R? This is a complex circuit compared to what I normally mod, so want to make sure I cover my butt before I start poking around in it!

If I wanted it to pulse with the "mod rate" pot, where would be the best place to tap into that voltage? Thanks!

For the Rate pot you would put the LED in series with VC1-3_L, nt in parallel. Lowering R42 might compensate or prove unnecessary. For the Mod_Rate I'd try a 10k CLR and LED connected to pin7 of IC9_B first. Do it on a breadboard where you can easily disconnect the LED and see if it impacts performance.

These are just educated guesses.

I only just saw this thread. I'm not sure how a CE-2 would sound with a purely sine wave modulation. I think it might ened up sounding a little lop sided because the peaks and valleys would be much more drawn out.

However, this is DIY so all ideas are a good starting point. My suggestion is to take a different approach and maybe adapt one of the Electric Druid microcontrollers to be the modulation engine. Then you could use all sorts of different wave types, not just sine and triangle. Take a look at the Flangelicious project and consider how you might have to work it into a chorus design. It might require a BBD with extra stages, or some other wizadry.

Update: the headers came today after all.

Dope! How about the coming soon stuff?

Well I have no choice except get them out ASAP (plus the other 10 that are basically ready) so I can work on the Microsynth. I'm gonna set a much better pace this year.

Also, I have a small handful of Archibald and Harbinger2 boards not listed in the store. PM me if you would like one.

Back in stock: SSABP, 9mmBB, CurrentLover, Freeloader, IMP, JunkTrunk, Kezurokai, PorkBarrel, Prognosticator, RoughCut, ScareBear, Shortbus, Skoolie and Transponder.

Couple notes:
-TrashCompactor: if you order this with the 4305 chip it will be soldered directly to the main PCB rather than an adapter board.
-Orders with Skoolies will not ship until Friday. The 8pin female headers I include with these were supposed to be here today but are running behind.



I will have more restocks coming probably the first week of February.
