Exploring free improvisations a little more, I found some hair clips around the house and wanted to see how they sounded on my electric 12 string. It sounded kind of interesting when I used a nearby screwdriver so I pressed record to see where things went.
Something about the metallic created some almost percussive textures, once the slide nullified the repetitive nature of a couple of the higher notes ringing out I was able to get some interesting textures. The input started going on my guitar, but it never cut out and I ended up trying to improvise with it which whilst is not reliable on any other occasion worked out for this recording. No effects apart from a little reverb on the amp which went a long way. I started flicking the hairclips towards the end which created some interesting rattling resonances.
