I give you the cheap-o-cello!
While looking through Tony Conrad images, I came across his LSD(Long String Drone) instrument and decided that I should just make one for myself. The original (from what I can find) had all three strings tuned to the same note, had a flat bridge and wa played with a guitar slide.
I had this setup that way for a bit, it makes great lap steel tones, but only has 3 strings, it’s weird to fret, and I wanted to give bowing a try. I have tried several heights, shapes, pickup positions, curved top nuts, flat ones, no nut, and my current favorite: the zip tie nut! I can switch between the guitar pickup and a contact mic that is wedged in there.
Having a lot of fun integrating it with voice and modular, building up textural loops with w/ filtered and fedback with 3 sis. Just waiting on an a-177-2 to show so I can set the w/ loop feedback levels/punch in while playing!
