1974 Alembic Series I basses

- These Alembics featured active electronics and five-pin connector along with the standard jack.
John (about the first one): Bought from Fred Walecki whilst holidaying in L.A.… I had it re-wired back to stereo by Peter Cook. He brought it along to a Who rehearsal when he’d finished — I plugged it in and it blew my mind. I jetted to San Francisco 3 days before the tour started and bought three more!
From the August 1989 Guitar Player
He happened upon a second-hand Alembic in a Los Angeles music store. “Someone had wired it incorrectly, so I gave it to my guitar tech, Pete Cook, to fix. Right before we were to leave for a U.S. tour, he brought it to a rehearsal, where I tried it and was, of course, blown away. I flew over early to order three more basses from Alembic, who eventually built me the Explorer-shaped models.”

From the August 1989 Guitar Player
Although [John] was happy with the bright, clear tone of the Alembics, and assortment of inconveniences ultimately forced him to move away from the instruments after more than a decade. “Unfortunately, the basses were very sensitive to the climate changes on our tour schedules, and I’d spend as long as a half-hour before every gig making adjustments. Also, I grew tired of the bloody 5-pin Cannon jack and transformer box I had to use with them. What finally put me off was when we did Live Aid. Right before we were to play, my main bass went dead because I’d accidentally crossed some wires while changing the battery. I ran for the backup bass but couldn’t tune it because there were no transformers backstage. At that point we were introduced, and I barely managed to get back onstage in time to start ‘My Generation.’ If you listen closely to the video, you can hear me tuning the D string as we go. I just about got it in tune in time for the bass solo. I sold the main bass to the Hard Rock Cafe — that was its punishment.”
From May 15, 2002, Guitar Center interview
I eventually changed to using Sunn 300-watt Coliseum Amps powering four 18″ PA bins plus additional 12″ cabinets (up to sixteen 12″ cabinets at one point).
From the November 1977 Guitar Player (read an excerpt of the article):
John Entwistle’s amps are the responsibility of Bill Harrison, who stands to the rear of the bass cabinets when the Who are onstage. Each of the two signals of John’s stereo output is sent to its own Stramp 4120 stereo preamp, where they are again divided and relayed to one of four Sunn Coliseum slave amps. The Stramps are turned all the way up, the Sunns set at about 5 or 6. The current speaker array includes a pair of Sunn W bins, each with an 18″ Vega speaker; two standard Sunn enclosures, each with a Vega 18; two Sunn 4x12s; and two Sunn 3x12s. Entwistle describes his goal: “Mainly the sound qualities that I am looking for in this particular amping system center around the fact that I like separation between low and high notes. I can have four different sounds going on at once, with the equalization of the preamps and four amp heads. Just flicking two switches on the preamps allows me to select which sound I want at any given point.”
