Goldbaby, the New Zealand retro perfectionists behind the Tape 808 sample set, just released Tape Drum Machines Volume 1, with a bunch of fantastically kitsch vintage gear like MPC's The Kit, Companion's Four In The Floor and the very cute Yamaha MR-10. All of these are then recorded on four different vintage reel-to-reel machines and sampled. For $24. If you're too cheap, the free samples page has a lot of goodness.
