Not quite in a whim, as I've been thinking about it for a while, but today I saw a pretty cheap Theremin on evilbay and snapped it up. I'm going to try running it through some weird modulation effects pedals and see if I can freak out Mrs Returns. After that, I figured it would be a really cool instrument for non musical kids to muck about with at my YBTB sessions.
I'm a tiny bit worried that I'm getting more and more like @HarrySeven by the day, but meh...I'll go with it!
Look out for some bloody weird videos soon!
Just because you're paranoid, don't mean they're not after you
