Guitar World, January 1984, "Carlos Alomar: Hard Driving Anchor Man For The David Bowie Show" by Gene Santoro

Alomar loves the concept of chimes, high frequencies, strange intervals and an odd bar of time superimposed on top of a very slick rock-funk format. Carlos' own guitar sound is a high-tech one, and any thing that he can pick up or throw into that to further its aims, he will do. He has everything he needs at his fingertips, and he signals the band with a nod of the head. Carlos will take a simple ninth funk chord and — before slapping it out — he'll slide up and down the neck, hit two dissonant intervals in between the funk and slap on his digital delay to make it sound like birds chirping. Then, he'll signal the band to go to the next section. Or, he might start off playing with the micro-synthesizer on, sounding like the guitar's under water, switch on the multi-effects with the sound of angels and then rip into an outrageous heavy-rock thing by slapping on some overdrive. This works out to the kind of sound, for example, he got in 'Fame': that is, funk chops all over the place laid over a clean, whack-flack execution; all kinds of cool chord inversions and substitutions; and the freedom to go wild with volume and sound effects through his mammoth rig of equipment in a huge stadium or hall.

Recently he has simplified his stage rig, and no longer uses the customized 700-watt system that in the past blew away the folks in the front rows. Now he plugs into two Roland Jazz Chorus Amps, with a Roland GP-120 that clicks in for solos. For special effects, he has two top-of-the-line Ibanez multi-effects digitals mounted on racks, and also uses two Electro-Harmonix micro-synthesizers. His favorite performing axes are his stereo Alembic, his 1958 mapleneck Stratocaster with a Kahler tremolo system and his new Steinberger six-string, which he was the first performer to introduce onstage.

Musician, March 1984, "Who The Hell Is Carlos Alomar?" by J.D. Considine, pg. 90

Carlos Alomar's criterion for his stage sound with David Bowie is fairly simple: "When I strum my guitar," he says, "I want to hear it come out of the amplifier just like on the record." To get that clean, well-manicured sound, he uses an Alembic stereo guitar, outfitted with Dean Markley strings (usually .009s), run through two Roland Stereo Chorus amps, with two Ibanez UE-300 effect units, a pair of Yamaha E-1010 delays, and twin Electro-Harmonix 203 guitar synthesizers. He also uses a Stratocaster, a couple of Yamaha guitars, and a prototype Steinberger guitar which he describes as "great, it's really great."

International Musician & Recording World, January 1985, "The Boy Keeps Swinging: David Bowie" by Philip Bashe

Carlos Alomar used an array of guitars: Alembic stereo electric, Steinberger prototype, acoustic, Spanish and 12-string. Amplification consisted of two Roland JC-120s and for effects, he employed two Yamaha E-1010 digital delays, Ibanez UE-400 and UE-405 multi-effects units, and two Electro Harmonix 230 guitar synthesizers. In this era of guitars that sound like every instrument but, Alomar opted for a fairly traditional and lightly textured sound.

"I didn't want too much of a synthesized sound," he explains. "I wanted to keep it balanced because of the horns on the album. And I didn't use the real heavy-duty power, because David's always screaming, 'No Heavy Metal!'"

Alomar played virtually all of the guitars on Tonight and details his unorthodox method of devising parts.

"I'll start off with the Alembic guitar and play one very complicated part, and from that I'll break it down into three parts and then play them all separately. This way you have your stereo placement: one guitar on the right, the other guitar answering on the left, and one guitar playing everything in the middle of the mix. It keeps the sound very interesting."

Heritage Auctions, October 2006, 2006 October Music/Entertainment Memorabilia Signature Auction #634, [Lot #22286 "Carlos Alomar's Alembic Guitar with Case."

Carlos Alomar's Alembic Guitar with Case. A beautiful, all original 1975 standard point Alembic guitar -- the oldest model in their history -- owned by David Bowie's guitarist/bandleader/songwriting partner and played exclusively by him on all of Bowie's world tours and recordings from 1976-2000. Custom made for Alomar in 1975, it features a zebra-mahogany body, walnut-maple neck, and ebony fingerboard. The Alembic company confirms that although the serial number on the headstock reads "75-156," marking it as the 156th instrument made by '75, that number also included top-end bass guitars made during the period, which was what the company was primarily known for. It was actually only the 40th (approximately) guitar made by 1975. The guitar comes with an ornate leather strap with the initials "CA" and an Anvil guitar case, used to ship the guitar internationally during tours, with Alomar's name stenciled on it. The case is, of course, a little battered from travel, but the guitar and strap are in Excellent condition with light rhythm pick marks on the front and belt marks on the back of the guitar, but no cracks, breaks, or repairs. A very rare axe with a lot of history behind it, this is one sweet instrument. With COA from Carlos Alomar himself!.
