First, did you know that RCA made a vacuum tube that was usable as a phonograph pickup?
Second, Feena Electronics. They introduced an interesting DJ MIDI controller in 2006. Since then, nothing. The last post to their forum was September 21.
Finally, this guy is building a duplicate of the old Metasonix Hellfire Modulator. He’s making a chassis for it out of plain sheet metal, and he apparently mated two toaster ovens together in order to bake powder-coating onto it. DIY FTW!!!
