I saw Devo last night at Shepherd's Bush. They were looking a bit older and greyer (and a little fatter in a couple of cases) than they are in the above photo, but their playing was absolutely spot-on. Very entertaining and totally barmy.
Guitars used were a Steinberger bass (strung right-handed but played left-handed), an Ibanez Talman electric, and a couple of early G&L guitars that sounded fantastic. (I say early G&L because they had a simpler headstock design - without the little pointy bit, if you know what I mean).
There was another bizarre carved-up looking guitar that was used by Bob 1 on "Smart Patrol/Mr DNA" for a rather manic solo and then some mechanism was triggered to break all the strings. I didn't quite see how he did that.
Mark Mothersbaugh (the singer) also played guitar on "Satisfaction" - it was left-handed Strat (played right-handed) with effects pedals gaffer-taped to the body. Also, it seemed to have the 2 centre strings missing.
BTW, does anyone know what the strangely-shaped guitar in the above picture is? I'd love to know. (I don't mean the bass - that looks like a Gibson Ripper with a somewhat modified body!)
UPDATE: A little searching on the web has identified Bob Mothersbaugh's current favoured guitar as being the
ANOTHER UPDATE: The Blue Potato Guitar has been identified! Thanks Nic.
