Have you seen Steve Vai’s Hydra guitar? It’s a one-off made by Ibanez and the more you look at it, the more stuff you realise it has.
Seven-string, four-string headless bass with half-fretless neck, 12-string with a different kind of half-fretless neck, Sympathetic strings, MIDI, coil split… it probably also has a garage door opener, one of those little Amazon buttons you use to order more laundry detergent, a slide whistle, a Rapid Antigen Test, snack drawer and a flea circus. I love it.
Check this thing out on the track ‘Teeth Of The Hydra’ from Steve’s forthcoming album, Inviolate.
But I’m gonna hazard a guess that we’re not gonna see this one in any publicly available form.
