Madbean Current Love Electric Mistress build oscillator noise.

[RRJackson]

This isn't specific to the Madbean build. I have this gripe with most modulation effects. I really like the sound this circuit makes in the lows and in the midrange, but then I can hear the sweep up in the highs and it annoys me. Like I said, I find the same fault with most modulation effects, so this isn't a gripe about the Madbean version of this circuit. I call it the, "Pennywhistle Effect." Is there any way to limit that high frequency swishyness? I'd just love it if the whistling wasn't audible.

Get a totally different delay device. I am still astonished that the bucket chips are in use today. 1,024 or so bits, when my dumb-phone's little ringer has mega-bits.

You can severely low-pass the output. On full speech/music this sounds un-natural. It may be useful for some guitar sounds.

You're not relative with Batman, are you?

The thing is, I've tried putting it in an effects return and rolling off the highs while mixing it with a clean signal. Mixing it with a clean signal doesn't sound good to me, BTW. Rolling off the highs sounds terrible, too. I like the effected high frequency content, but I don't want to hear the whistle of the oscillator.

Some modulation effects avoid that, but not many. The old Maestro phaser was great for that. I own the Heptode copy of that circuit and it's my favorite modulation effect. I just wish I could get the same kind of thing to happen with the Electric Mistress circuit, because I love what it does other than that.

I have an EM clone similar to the Madbean CL and I wouldn't say it "whistled".
If I don't play anything through the effect then I can hear "swish" but that is just the peaks & notches in the flanger's frequency response filtering the noise.  It's not the LFO that the problem.  It's just part of the price of using a noisy component like a BBD to produce a delay.
