People were somewhat perturbed by my description and furthermore that it was pretty accurate. Now, bringing it up two octaves, here is a note that I would consider a pretty squishy F4:
I'll open the floor here for y'all to discuss some notes and their "feel". Have a crunchy G♯4? A coarse B3? A velvety E♭2? Drop them here! I'm curious to see what y'all will come up with.
