Hi, lately I've been listening to Freddie Dredd a lot and I started wondering how to make a beat like that. Specifically, I'm interested in this track:

I'm not talking about the 808 kick or snare, but the main, leading sound in this beat. I wonder if it's a sample? Or is it a sound designed in a VST? In my life, I've gone through millions of presets and I've never heard anything similar. Maybe one of you has such knowledge and a trained ear that you will be able to verify whether it's a sample or a VST?
And here's a brief info from Wikipedia...
Dredd's production style is primarily sample-based, with him often using samples from bossa nova music and Japanese anime and video games accompanied by 808 cowbell melodies and phonk drums. His vocals are often very crude and aggressive in both lyrical content and mixing, with his vocals often being heavily bitcrushed and distorted. The genre would be considered to be labeled as phonk,[10][11] a subgenre of hip hop. Many of the sounds used in his tracks are reminiscent of the Memphis rap mixtapes from the mid to late 1990s.
