John Flansburgh

Behind Flansburgh in this video, we can see a Matchless Chieftain, most notably at :48s.

John Flansburgh is seen using a Fender Vibrolux Reverb amplifier (blackface version) during a recording session for their lead single "Can't Keep Johnny Down" off of their 2007 album "Join Us."

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.

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.
