Warwick

Thumb

Named for one funk player’s thumb, fixed by Jack Bruce’s complaint, and the bass Bruce said he’d quit without.

Germany, 1985. An American bassist named John Davis, who pops his strings hard with his thumb, has been working with a small new bass maker. The maker’s next bass is built around that style: a tiny body, twenty-six frets, and the first run wears Davis’s initials.

Side A

A1

A bass named after a thumb

Most basses are named after a place, a company, or somebody famous. This one is named after a thumb, and not even a famous one.

In the early days of Warwick, the German company Hans-Peter Wilfer started in 1982, an American bassist named John Davis had a hand in a new design. Some say he was a serviceman stationed in Germany. His style was funk, popping and slapping, with the stubbiest finger on his right hand doing most of the work. In 1985 Warwick built a bass for exactly that kind of playing, and the first run had his initials on it: the JD Thumb.

Wilfer said later it was “the first bass with such a small body.” It was made for one player’s hand. It ended up belonging to somebody else’s.

A2

Small body, hidden neck

Warwick’s earlier basses had leaned on other people’s designs. The Streamer borrowed its curve from Ned Steinberger. By that reckoning, the Thumb was the first one that was all Warwick.

It’s small, which makes it easy to slap without wrestling a big slab of wood. It has 26 frets on a full 34-inch scale, and you can actually get up to the last one. The neck runs all the way through the body, but you can’t see it: the top is cut from one piece into three sections, two wings and a plank over the neck, and fitted back together so it looks like one solid body. The bridge pickup sits on an angle so the higher strings speak up.

The early ones were bubinga and wenge, finished in oil and beeswax. The balance wasn’t perfect, though, and that’s where Jack Bruce comes in.

A3

Jack Bruce complains

Jack Bruce, from Cream, was already one of the most famous bassists alive. The stories of how he found the Thumb don’t quite match. Wilfer says Jack saw one in a shop in Cologne and bought it, and that’s how the relationship started. Jack’s version, in his biography, has him buying one in a small-town shop and telling the factory the balance was wrong:

…and that’s where the Warwick Thumb comes from.

Both can be true. Either way, Warwick restyled the bass around him. By 1987 the JD badge was gone. The five-string had come in 1986, with its pickups moved in close together, and a six-string followed in 1988. In 1990 Warwick made a hundred numbered fretless Jack Bruce Thumbs, with little red lights down the side of the neck. Not many people bought them. The idea later went into the catalog as his signature model.

Prince, Fishbone, and a record advance

In the mid-’90s the Thumb became Prince’s bass of choice, on stage and in the studio. He had three that are still at Paisley Park: a white four-string with a custom eye painted on it, a black five-string with the lyrics to “Gold” written on it in gold, and a natural fretless. Sonny T played the black one in the “Gold” video. Rhonda Smith played the fretless in “The Holy River.”

In 1991 a magazine listed Fishbone bassist John Norwood Fisher’s gear, starting with “a Warwick thumb bass with a bubinga and wengewood body.” He bought his first one from Robert DeLeo of Stone Temple Pilots. Ryan Martinie of Mudvayne spent part of a record advance trying a whole pile of basses, and the Thumb was the one that worked. On “A Key to Nothing,” as he put it, “The rest of the song is my Warwick Thumb 4.”

B2

The one he couldn’t put down

In 1993 Warwick built Jack Bruce a fretless Thumb in Brazilian rosewood, the first one they made for him in that wood. He took it to his Rock and Roll Hall of Fame induction that year. He played it with Cream again at the reunion in 2005, with “White Room” and “Sunshine of Your Love” near the end of the set. He played it on Silver Rails, his last album, in 2014.

He said that if anything ever happened to that fretless Thumb, he might as well hang it up.

John Davis’s thumb gave the bass its name. Jack Bruce gave it its balance, and then he kept it busy for almost thirty years.

Construction

The job was a small bass you could slap without fighting a slab. Hans-Peter Wilfer, Vintage Guitar (Willie G. Moseley, July 2017): designed for comfort in slapping and playing in a virtuosic way, “the first bass with such a small body.” Chicago Music Exchange: 26 frets, and you can play up to the last one. Bass Center’s megabass.it chronology (12 July 2016): the first bass designed entirely by Warwick, if you treat the Nobby-Meidel and the Streamer as Steinberger and Spector cousins. That is the split. This table is not that curve (warwick-streamer).

Warwick itself starts 13 September 1982. Vintage Guitar: Wilfer’s father, Fred, had founded Framus in 1946; Hans-Peter started Warwick that September in a tiny Bavarian workshop. Guitar-list dates the Thumb to 1982 — the company year, not this bass. MusicRadar (Roger Newell, 28 October 2011), Vintage Guitar, Sweetwater, and Wilfer put the Thumb in 1985. Wilfer, Chicago Music Exchange: “The first thumbbass we made in 1985.” Keep 1982 as the shop. This plate starts in 1985.

The first run wore JD. Vintage Guitar: JD Thumb Bass, for expatriate American bassist John Davis, whose popping, funk-based style used the stubbiest digit on his right hand. Bass Center: a U.S. serviceman stationed in Germany who took an active role in the model. Then Jack Bruce. Wilfer: Jack saw it in a Cologne shop, bought his first, and the relationship started. Sotheby’s quotes Harry Shapiro, Jack Bruce, p. 284: Jack bought a Warwick in a small-town shop, told the factory the balance was wrong, “and that’s where the Warwick Thumb comes from.” Keep both. Wilfer has a 1985 bass Jack found. Jack has a balance complaint that restyled it.

What you get is a hidden neck-through. Vintage Guitar, on a 1986 original: seven-layer wenge and bubinga assembled so it doesn’t look like a neck-through; a cap of three sections — two wings and a plank covering the neck as it courses the body — cut from one piece and installed to look contiguous. Wilfer: measurements of hundredths of millimetres. Bass Center: four wenge strips separated by three wider bubinga strips, 26 frets, J/J, the bridge pickup on the diagonal so the D and G speak up. Vintage Guitar the same angle. Oil and beeswax on bubinga. Brass Just-A-Nut. Schaller tuners, straplocks, and a one-piece bridge of Wilfer’s design. Early boards are wenge. EMG, Seymour Duncan, Bartolini, and Schaller sat in the routes before MEC.

Not the Streamer. Visible through-neck, Ned’s NS curve, reverse-P and J, 24 frets (warwick-streamer). This is the small hidden-neck with 26. Not Stage II, which borrowed the hidden neck and is still a Streamer. Not Thumb BO. Bass Center: first bolt-on 1994–95, walnut, 24 frets, then bubinga 1995–97. Guitar-list: 1994. Warwick Forum: 1993–94. Keep 1993, 1994, and 1995. BO is screws, not this table. Not Thumb SC. Wikipedia: forum contest, NAMM 2010, swamp ash with bubinga pommelé top, flamed-maple neck, soapbar humbuckers. Single-cut. Not Buzzard (Entwistle, 1985–86). No Gibson SKU.

Then the instrument changed. 1986, five-string: Bass Center has the neck pickup moved in, almost against the bridge pickup and parallel — not a four-string with a B bolted on. MusicRadar: first five-string produced in Europe, that source’s claim. 1987, the two-piece brass bridge still on the spec sheet. Bass Center: JD drops after a closer restyle with Bruce; leftover plaques on transition instruments. 1988, six-string, Bartolini soapbars. 1990, MEC pickups, February on Bass Center’s chronology. Jack Bruce limited that year: Bass Center, 100 numbered fretless four-strings with red LEDs. Demand was thin; the idea later sat in the catalogue as a signature. 1992, lighter alloy bridge; Bass Center says the already-soft balance got worse. 1995, the shop left Franconia for Markneukirchen.

German Wikipedia: Custom Shop is Masterbuilt, Germany; Pro Series is Teambuilt, also Germany; RockBass is “Standard,” China. Wikipedia’s RockBass list does not include a Thumb this pass. Same silhouette at two German prices, bolt-on under it. The table is Masterbuilt NT 4-string: pommelé, wenge/ekanga, tigerstripe ebony, MEC J/J, 3-band lithium, two-piece brass, Just-A-Nut III. Classic vs current: 1985 JD — seven-piece wenge/bubinga, wenge board, EMG or Duncan, Schaller one-piece, short horn — against that living Markneukirchen 4-string. Same small body. Same hidden neck. Same slug.

Players

Do not hang a Streamer, a Buzzard, or a Jack Bruce JB3 on this plate. Do not recruit Mike Inez or Robert Trujillo from the Streamer list. Do not flatten L.D. 50 onto a Thumb Martinie had not bought yet.

Jack Bruce (Cream). The player this bass kept. Official site: after Aria and Spector long-scales he found Warwick; the Jack Bruce Signature is a modified fretless 4-string Thumb with MEC and side LEDs. Sotheby’s lot 24: 1986 fretless, serial D369 86, Seymour Duncan, one of his first; BBC South Bank Show with Clapton, 1987; 1989 U.S. tour with Ginger Baker and Blues Saraceno. Lot 36: 1993 Brazilian rosewood, serial A-003638-93, the first Warwick made for him in rosewood — Rock Hall induction 1993, BBM mid-1990s, Cream reunion 2005 (closing half: “White Room,” “Sunshine of Your Love”), Silver Rails (2014). Jack, via Sotheby’s: if something happened to that fretless Thumb, he might as well hang it up. Vintage Guitar: two signatures; the first a limited four-string Thumb, the later one reminiscent of his ’60s Gibson EB-3. The JB3 Survivor (2012) is that later idea. It is not this table.

Ryan Martinie (Mudvayne). Guitar World (Chris Jisi, 22 September 2024, from a January 2003 Bass Player tour of The End of All Things to Come): mainly a Warwick 4-string, tuned C G C F. “The rest of the song is my Warwick Thumb 4” on “A Key to Nothing”; verses on a fretless Pedulla Buzz. L.D. 50 (2000) is the earlier Ibanez Soundgear / Dean 5-string tuning (F# B F# B E). Do not mash them. Warwick NAMM 2013: record advance, he tried a whole crap ton of basses, the Thumb was the one that worked; no factory alterations at first.

Prince. Guitarcloud, from Prince — Guitar & Bass (Paisley Park Archives): preferred live and studio bass in the mid-1990s, Act II tour onward. Three Thumbs, all now at Paisley Park: a white four-string with a custom “eye” graphic (Jeff Munson design, Steve Parke airbrush), seen on The Gold Experience and Emancipation stages; a black five-string with the lyrics to “Gold” in gold lettering; a natural fretless four-string, near-mint — Rhonda Smith plays it in “The Holy River” video. Sonny T played the black/gold five-string in the “Gold” and “Endorphinmachine” videos.

John Norwood Fisher (Fishbone). Musician (Roy Trakin, May 1991): “a Warwick thumb bass with a bubinga and wengewood body,” plus a fretless Fender and an Alembic. Equipboard: Warwick interview in which he says Robert DeLeo sold him his first Thumb. Album-to-bass credits for named Fishbone sides are unpublished here.

Also known to play stays short. Wikipedia: custom fretless seven-string Thumb NT basses for Jeroen Paul Thesseling (Obscura / Pestilence). Those are custom objects. Do not recruit Entwistle, Inez, Trujillo, or P-Nut from the unsorted Warwick artist list.

Rarity

You can order a new Thumb NT from Markneukirchen. Masterbuilt NT, Masterbuilt BO, and Teambuilt/GPS BO all coexist on this silhouette. GPS is not a Masterbuilt NT. Custom Shop is the limited current line. It is not vintage rare. Wikipedia’s RockBass list does not print a Thumb this pass.

Warwick does not publish Thumb unit totals. None invented. Serials date a bass; they don’t count a model. Bass Center: about 60–70 instruments a month in 1984, about 100–120 a month by 1990 — company-wide, not a Thumb census. German Wikipedia: about 4,000 electric basses and guitars in 2009, company-wide. Same caveat. Bass Center on the 1990 Jack Bruce limited: 100 numbered fretless four-strings. Wikipedia on the 2001 Limited Edition Thumb BO: 150 that year. Named limited runs. Not a 1985 factory total.

What is actually thinner: JD-badged short-horn Thumbs from 1985; EMG- or Duncan-era instruments before MEC (1990); seven-piece wenge/bubinga before the living five-piece ekanga; first-year five-strings (1986); the 1990 Bruce hundred. Bruce’s rosewood A-003638-93, Prince’s eye-graphic four-string, Martinie’s C G C F four-string are unique objects. They are not a vintage Thumb.
