Ever since I built a few pairs of Jules' hydrophones, I have been interested in new ways to make recordings with things other than traditional diaphragm microphones. I have been thinking about building a set of contact mics using Jules' circuit and a flat piezo disk. One of the things I want to record is a passing train.
Then I got to thinking...I also having been tinkering with electric guitar builds and I have a few cheap pickups from kit guitars where I replaced them with better ones. Rails are steel. Like guitar strings.
What about putting a pickup on each rail. Run them through direct boxes and into my Mixpre and record a passing train?
