You may remember the galaxy guitar from this post, and that it was completely fucked. Well, no more! I replaced the faulty transistor, so now it's REALLY loud, and added a couple of innovations -- I found that I could make an LED light up in response to sound by connecting it across the new transistor - so I wired that up and stuck it out the front of the galaxy guitar, my inspiration is at the top.
. Now it can be wiggled around in front of the photoresistor, allowing for excellent expressive control.
I also added a voltage control input that has some (limited) interactivity with the pitch control. It works extremely well with a piezodisk, and not much else. A wonderful effect (which, of course, I can't find now) involves a piezo I attached some wires to, then strummed the wires while playing the galaxy guitar, creating really warbly noise and junk sounds.
