Greg Ginn

As you can see. Ginn is playing his "Custom" Dan Armstrong right here. Ginn modified his Dan Armstrong with a Les Paul-style stop tailpiece and a variety of pickups that would frequently have to be replaced when the pickup shorted out.

See this fucking picture

Greg uses one of these Modulus Graphite Black Knife strats, his one has one pickup and one volume knob - sort of like a Tom Delonge strat

Hard to see it in the background but as soon as you notice the big SMF logo behind Greg's head, at least there is no mistaking what it is. Possibly Greg's very first guitar head considering how early this photo was taken in his life! Also these things are tube amps, therefore he most likely was in the long term process of really figuring out what kind of sound he was looking for. Greg actually went through a variety of different guitar heads throughout his career with Black Flag; some of them were tube amps like this one, however most of them were solid state. He's used guitar heads made by SMF, Sound City, Peavey, Roland, Yamaha, theres even a couple photographs of him with a Marshall guitar head (However it is also possible he simply happened to be next to a Marshall head that belonged to a different band). I really don't know what kind of guitar amps Greg uses nowadays.

(Right behind his head). One of the most circulated photos of Greg's career, unfortunately the only evidence I'm aware of as fas as the origins behind Greg's particular amps he used during bLAck fLAg's ten year run; was financial limitations. Black Flag simply didn't have ample money during their ten year span, naturally this resulted in the band having no choice but to gravitate towards low-cost equipment that they could afford. Greg in particular went through about a handful of guitar heads (mostly solid state Peaveys); whether Greg "loved" how they sounded or "settled" for them, I have no idea.1983 was a pivotol year of Greg's career beause it galvanized his intentions of having absolute creative control over ANY band he would play in; tone chasing became more prevalent in Greg's equipment choices. My War (1983) was Greg's offical transition into guitar pre-amps and power-amp rackmounts, the first being a Roland SIP 300. You can listen to Greg play guitar through it on My War (1983), Family Man (1984) and Slip It In (1984). Greg would no longer use Roland SIP 300 after 1984.

Greg Ginn play the bass with the Texas Corrugators

I have no source but I know for sure that he used one. It's very well-known among fans... just find some words from the man himself and edit this, please.

Greg Ginn used a Theremin as part of his stage setup for his electronic music-based project Greg Ginn And The Royal We. The Theremin can be seen mere seconds into the supplied video, and throughout the clip he frequently takes a hand off of his guitar to play the Theremin. He also incorporated the Theremin into Black Flag's live show during their ill-fated reunion tour and related album "What The...?" and his short-lived band with Mike Valley, Good For You.
