Modern Boss DF-2 Super Feedbacker & Distortion Type Pedal?

[Abe]

So back in my younger days my Dad had a Boss DF-2 Super Feedbacker & Distortion effect pedal my brothers and I would use sometimes as kids. It wasn't super great but it did have the interesting feature of holding and sustaining a note or harmonic feedback. You'd play a note and press it down. If it was one clean note it would hold that endlessly while the pedal was pressed down. if you played a chord or multiple notes and did that it kind of had a mind of it's own. Lots of older folks here so I bet some of you may be familiar with it. Would be a feature I'd be interested in if there are modern options that are similar yet better. Wondering what those options may be. I could buy a pricey old used one off eBay or Reverb but I'm wondering if there is something new and modern that does the same thing but better. Let me know if you have any ideas for me. Picture of what it was below.

I had this pedal, the feedback mode was cool. I don't think there's a modern version of it. But the originals shouldn't be hard to find.

The EHX Freeze can possibly do something similar with holding the note but it's a different process altogether.

I didn't know this pedal had existed until a few months ago, seeing it on youtube grabbed my interest because I use a torpedo captor to record my amps but I wanted feedback for certain songs. Boss does make the FB-2 which is a booster/ feedback, used are going for under $100. Digitech also made the FreqOut which is going around $200.

I have the Freqout. It's alright, but I prefer natural feedback.

Hmm. Did some reading and watched some videos and have become most interested in the DigiTech FreqOut. A bit more advanced of an acquisition than buying one of the old Bosses used for significant $. It also has the most options and abilities it seems. However I can tell that some of its noise is not quite organic sounding enough to be better than what my hollowbody is naturally inclined to do through tubes. I feel it can be somewhat useful though.
