A 1960s era National Resolectric that I've owned since March 2001. A very funky instrument that has a fine honky sound acoustically and is just plain nasty pluged in. Some of the resonator echo comes thru the single coil pickup. No controls what so ever, couldn't be simpler electronically just the pickup and the jack. It's possible that the electronics were added after purchase, but if so it was a nicely done job as the routing for the pickup is very clean.
