Tim at Discchord did a fine job with that video. It’s given me GAS for the TT-303 even though I hardly play acid house. I’ve read that the TT-303 isn’t made with great build quality, but Devilfish is planning a mod for it that includes upgrading knobs, switches, etc. to improve the build quality.
However, I don’t regret ordering the three Volcas as a bundle. The Volca Bass is really a full-range monosynth and not a bass-only synth - the “bass” part of the name being Korg’s playful poke at Roland. I look forward to doing all kinds of naughty things to all 3 Volcas with my Octatrack.
