I have a huge stack of records that prove it was used heavily throughout the 00s. And the 90s too

It's amusing to see comments implying that the TB-303 is some kind of neglected classic. It can only be considered to have been forgotten for perhaps the two years after Roland ended production in 1984.

"Acid Tracks" came out in 1987 and I genuinely feel like I've been reading endlessly about the 303 ever since.
