I've never attempted to record a Steel guitar instrumental until recently when I recorded a Slow MOR blues jam as incidental music for a DVD, but my favourite piece of my own recorded Steel playing (non pedal) is on the intro to "I Love the South", a song about a visit to Tennessee and Kentucky a few years ago.
It's here, if you click the little radio!
