Amplified Music Box
I had a couple of cheap music boxes lying around which I had bought a while back. They both play Harry Potter, one in the box, one which has been ripped out of the box. I found a point in the melody that played one note and recorded that a few times. I started by sitting the music box (the one with no box) on the body of my acoustic guitar, since my pickup has an internal mic too, that worked fairly well, but after a while the battery in my pickup died. I didn't have a spare so I decided to turn to my electric. I recorded the music box by sitting it on the strings above the bridge pickup. Unfortunately the signal wasn't loud enough to distort the music box as much as I wanted but the experiment still gave some results I am happy with, especially with some reverb and delay.
I might return and try this again in the future, perhaps in a space where I can get some more volume (not my living room..)
Played through my Fender thinline tele, bridge pickup, through some guitar pedals (cant remember the exact ones), into my Fender hot rod deluxe amp, and recorded with an SM57.
