First Electric Instrument Ever Recorded

The first electric instrument ever recorded was Bob Dunn's steel guitar when he was a member of Milton Brown and his Musical Brownies headquartered out of Fort Worth. It is curious to consider that Bob Dunn's Hawaiian steel was actually recorded before Les Paul's solid body namesake had been developed. For the record, Dunn's original electric recordings were on a standard guitar played in Hawaiian style with a rudimentary pickup rather than on what is now called the lap steel.

Here is a link to some of the earliest steel guitar recordings ever made:
