I’ve been breathlessly awaiting one of these since I saw this. It’s Korg’s Miku Stomp, a spinoff from the company’s Vocaloid voice synthesizer. It tracks your pitch as you play and responds with a synthetic voice that forms various syllables and phrases.
There’s some cheating here: The effect’s latency is quite severe, so I had to slide the Miku track back in time while mixing. Its triggering is also inconsistent, so I replaced a few notes. Miku tracks best when playing melodies on a single string, hence my awkward, position-jumping fingering. (Actually, it tracks pretty well when you play slow melodies full of sustained notes. But steady eighth-notes at 155 BPM as heard here is a major challenge.)
One of the pedal’s most interesting aspects is the way it interprets slurs. When there’s no break between notes, Miku sings a sort of pseudo diphthong. Detached notes get a syllable with a clear transient.
IMHO, the inescapable facts that Miku is silly and doesn’t work terribly well doesn’t diminish her total awesomeness. No doubt about it: heaviest stompbox ever.
The tune, of course, is “Georgy Girl,” which I’ve loved since forever. It was a blast recording the backing tracks with classical guitar, ukulele, ukulele bass, 12-string, toy piano, M-Tron Pro, and a mix of live and sampled percussion. And of course, gobs of my favorite reverb effect: Universal Audio’s EMT140 plate simulation. Yum.
