Go ahead. If you want to make it even more accurate I suggest actually leaving spaces at 100% and only putting a more noticable pitch shift into a short spot and then have that loop.
So for example, quick shift down from 100 to like 97 and up back to 100% then leave it at 100 for a bar or something like that and then have that loop.
Even though it's straight forward, I'll explain it. Essentially 2 subtle things happening here. Or three.
The sample and the drums are running through a rasselbock with naswalts pitch automation trick, but the tone knob is just subtly shifting from 100% to some 97%. The trick was to choose the right speed. You can exaggerate the tape deck motor struggling by making the wobble loop faster - 1 cycle in 1/16th note or so.
You are welcome. I use the sidechain clipper technique a lot for "parallel clipping" in case you want something to distort in relation to another sound. So far I've only tried it with bass, but there are probably other uses too.
Then make the compressor a clipper/limiter by completely lowering attack and release, put the ratio right up to infinity and turn the sensing to 0 ms rms (or rather turning it to peak). On the sidechain signal, use an EQ to cut the high end and boost the ever-living hell out of the low end until it is clipping (this will not be audible, since it's just sidechain), lower the threshold to your distortion liking and now you should have an inconsistent hiss.
