John Flansburgh

John Flansburgh used a Gibson SG Standard in the 2000s, as noted on the TMBW: The They Might Be Giants Knowledge Base.

According to the official wiki :

Fender Mustang (light blue) - "My first guitar was electric. It was a baby-blue Fender Mustang. I learned to play while working at a parking lot in Washington D.C."[5] He started out with only the top three strings, as it was easier to wrap his hand around and form chords. There are photos of him playing it in about 1980-81, during The Blackouts and The Turtlenecks period.

According to the official wiki

Gibson ES-330 (cherry red) - One of Flansburgh's earliest guitars. "I never even thought about other guitars I enjoyed it so much. […] It is the double speed guitar on the recording They Might Be Giants—flown in from the original demo made five years before the album) but alas it was stolen in a big apartment theft."[13] This was the guitar used at the El Grupo De Rock And Roll show.

According to the official wiki :

Gibson L1 acoustic guitar - Custom built during the John Henry sessions.

According to the official wiki :

Gretsch Bo Diddley prototype (firebird red) - Borrowed for use in the video for "(She Was A) Hotel Detective" (1986).

Flansburgh (who considers his Arbiter Fuzz Face (26) “the ultimate fuzzbox”) has a similar rig — only “much more difficult to operate.” In fact, he hopes to go back to a more primitive setup. “I look back on having an open-reel four-track,” he muses, “where I could just plug my guitar into the front. The minute you get a patch bay — unless you really are an engineer — you can’t work as efficiently. It seems efficient because it’s much more versatile. But home recording isn’t about versatility. It’s about getting the idea down quick.”

John Flansburgh’s amp is an original Matchless HC 30 head and a Xits (custom) 2-12 cabinet. “We use an SM57 off the axis of the cone to balance out the 3k that is prevalent in the mic,” monitor engineer Carter explains. “Both Flans and Dan Miller use JDI SGI line drivers to help balance out their signals, then run through Sennheiser G2 wireless systems.” Flansburgh’s footpedal gear includes the Radial SGI TX and SGI RX, Boss Noise Suppressor NS-2, Electro-Harmonix micro POG, MXR micro flanger and Semaphore tremolo.

John Flansburgh, in a Tumblr post, confirmed the use of the Roland R8 drum machine, stating, "...using the Roland R8 drum machine which was kind of the last of the big drum machine libraries (some very very familiar sounds from big budget dance tracks–anything new jack swing styled tracks of the moment C+C Music Factory, etc.) The sound was much crisper while still often realistic."

John Flansburgh mentions using the Otari 5050MKIII-8 tape machine during the Flood tour in 1990, as detailed in a Tumblr post.

John Flansburgh confirms the use of the Moog Micromoog in his music through multiple Tumblr posts, where he specifically mentions employing the keyboard as a drum machine. He achieves a snare sound by "using the white noise generator with a quick attack and slow decay." This information is corroborated by the TMBW: The They Might Be Giants Knowledge Base.

In this Dec 15, 2009 article for Magnet Magazine, John Flansburg, as co-guest editor for the month, details his use of the Boss DR-110:

The DR-110 was an early tool for TMBG. There is nothing real about the sounds that came out of this early “pro-sumer” drum machine, but more singular to the DR-110, there was nothing particularly big sounding about it, either. The graphic display can be tapped into, which put it well past the pre-programmed “accompanist” rhythm boxes that were created for console organ players, and hearing the results of an entirely hypothetical graphical idea turned into a rhythm wasn’t usually successful but was still fascinating.

Additionally, in this 2025 Tumblr post, John confirms that the band used the Boss DR-110 Dr. Rhythm Graphic for early Dial-A-Song recordings around 1984. This includes its use on the song "1999", the first demo of "Don't Let's Start", and tracks on the 1984 Promotional Demo Tape.

John Flansburgh confirms the use of the Hohner Special 20 harmonica on the track "32 Footsteps," as stated in a response on Tumblr.

John Flansburgh said he used the TC Electronic Booster + Line Driver & Distortion on John Henry, running into a Fender Deluxe and then a JCM 900 half stack; in a Tumblr post, he called it “the final secret weapon” on the Deluxe amp and said it added “a millisecond of delay” to the sound.

In a Tumblr response about the recording of John Henry, John Flansburgh said he used “my Marshall JCM900 head and 12x4 set up ‘crunchy’ on one side and my Fender Deluxe on the other,” supporting that he used a Marshall JCM 900 Lead Series Model 1960A 4x12" Angled Guitar Speaker Cabinet. This is probably part of the Marshall Amp he bought for Apollo 18.
