The Doors – The Doors

Per The Doors Guide website - a website that aims to be the ultimate resource for one of the most innovative bands to come out of the west coast music scene in the late 1960s — THE DOORS":

"Robby Krieger plays a red 1964 Gibson SG Special with P-90 pickups on the first two Doors albums and for a bulk of the group's live shows from 1966-1970 (later with an added tremolo bar). Sadly, this legendary guitar was stolen and remains missing. I have the guitar's original serial number so anyone who believes they've found it can contact me for confirmation. Note: Robby sometimes incorrectly refers to this as a '64 Gibson Melody Maker."

At about 1:35 during this video for Reverb, Krieger discusses his studio rig for recording with The Doors: "Recording wise, it was the SG and a Twin Reverb. That was pretty much it." The recording dates for the first two Doors albums indicate this would have been a Blackface model (the Silverface variant was not manufactured until 1968, at which point "The Doors" and "Strange Days" had already been recorded and released).

This photo shows Manzarek with a Vox Continental organ during a Doors concert at the London Fog in 1966. This was the organ Ray Manzarek played in the early years of the band. It can be head on every song from the band's eponymous debut album, as well as several later hits such as "People Are Strange," "When the Music's Over," "Peace Frog," and "Love Her Madly." Manzarek started touring with a Gibson G-101 (Kalamazoo) around August/September 1967, though the Continental made a few more appearances such as on the PBS Critique in April 1969 and at the Aquarius Theater in July 1969.

Ray described his use of the Vox Continental and his subsequent switch to the Gibson G-101 in a 2008 interview with Modern Keyboard:

The very first piano, or the first electric keyboard, I used was a Wurlitzer. We didn’t really play a lot of gigs with it, so it didn’t really count. Then we got a deal with Columbia Records; and Columbia owned Vox. Billy James [the Columbia A&R man who, in 1966, signed the Doors to a contract that ultimately produced no records] said, “Do you guys need any equipment?” We said, “Oh God, yes.” [laughs] He said, “We own Vox.” I said, “Vox…VOX. Oh my God, I can get a Vox organ like the Dave Clark Five. Yes I need an organ.” So we went out to Vox and I got an organ and an amp. I couldn’t believe it. It was free.

I played a Vox Continental for the first half of the Doors’ career. Until Columbia sold Vox to an Italian company. Vox was an English firm originally. And the Italian Vox Continentals just didn’t hold up. They started falling apart. Even the old ones I used to have to replace every six months. I would break them just by playing too hard. The keys would start to stick and I would fuse everything. So I’d have to throw it out, get a new one. Once every six months wasn’t bad. But once Vox was sold to the Italians, it was like once a month, once every other week.

I said, “Well that’s it. I can’t use these anymore. I’ve got to get something else. What else is there?” There was the Farfisa and there was the Gibson Kalamazoo. Now I would have gotten the Farfisa, except the top was rounded and I couldn’t put the Fender Rhodes bass on it. I needed something with a flat top. And the Gibson Kalamazoo was the only one that had a flat top. So that’s what I used—a Kalamazoo—for the rest of the time.

In this photo, Manzarek can be seen playing a Fender Rhodes Piano Bass on top of his Gibson G-101. Because the Doors did not have a bass player, Manzarek would play the bass lines on the Piano Bass with his left hand. He usually opted for the gold sparkle top model, which he'd place on top of either his Gibson G-101 or Vox Continental organ.

This webpage talks about the Ludwig Mod Orange kit Densmore used with the Doors. One of the things about it is that this kit had a clear resonant head for sometime and later replaced with a drum head with the Doors logo on it. John Densmore's Facebook page had a post that said "For all you drummer aficionados - a little info about John's Mod Orange Ludwig Downbeat kit" which linked the webpage for anyone who wants to know more information on his Ludwig kit
