I’m not referring to an electric steel guitar, but an acoustic resonator, or resophonic guitar, played lap style. The Dobro is a staple of bluegrass, and is prominent in older country. You hear it in other styles too sometimes.
The best answer I can think of is “Looking Out My Back Door” by CCR. I know there is some uncertainty as to what constitutes ‘prominently’ - the solo is on a regular (electric) guitar, but the Dobro is an important part of the sound.
I’m not sure, but the guitar sounds like a wooden flat top (as opposed to a resonator), and the part played on it sounds like a bottleneck slide (i.e., upright, not lap style).
Does Lynyrd Skynyrd’s *The Ballad of Curtis Loew *feature a Dobro? The titular character plays one, but I don’t know if the same can be said for any of the band members.
Just to clarify, my use of ‘prominently’ refers to how prominent a part the Dobro plays in the song. There might be some very famous songs with a Dobro buried down in the mix, practically inaudible. But LOMBD wouldn’t be the same without it.
If the OP is referring to resonator guitars in general, a National is as appropriate as a Dobro. Knopfler certainly plays a resonator in concert, and I imagine he played one on that album.
That’s probably the winner. But Rory Gallagher was big in Europe in the 1970’s and he was another one who regularly pulled out a resonator guitar for acoustic sets.
I think Soundgarden’s “Burden In My Hand” has a resonator strumming the main chords. Tons of other guitars on that recording, but if you listen closely, the resonator plays all the way through the tune.
It’s certainly possible that’s what they used, though of course what it is supposed to be is an acoustic guitar being heard through a crappy little mono radio speaker (you can hear the stations being tuned just before the tune starts).
