Mike Starr

If you watch Would? In the music video, you can see that his Spector bass has black tuners which the NS-2a basses had, and dotted fret markers which the NS-2A basses also had. The bridge is black with black tuners and hardware like NS-2A basses have so this is the case. However I’m almost positive he recorded Dirt with a NS-2.

Throughout the video we can see Mike playing his sunburst Spector NS-2. He also owned a white and a black one.
