Marcus Mumford

Marcus is seen playing a set of Ludwig Black Oyster Pearls in this picture.

He uses this guitar in a lot of videos, like 'Little Lion Man' or 'White Blank Page (Bookshop Session)'. This is one of his favourite instruments, in fact it used its in a lot of concerts.

In this video source, you can see Marcus Mumford with a Martin D-28. He was also mentioned on the Martin Guitar Ambassador page. The July edition of Guitar Buyer has an article on Marcus' guitars and setup and includes two Martin D-28s are called "Mary-Kate" and "Ashley".

At 0:09 in this video, Marcus Mumford holds a Fender Jazzmaster.

In this video, at 0:11, one can see Marcus Mumford playing a Fender Telecaster on the left side.

In the video you can see Marcus playing a Gibson 1968 J-50 with The New Basement Tapes.

He uses this electric guitar for live performances of "Bellow my Feet". In the video of their Letterman performance he can be seen using one,

As far back as 2011 Marcus could occasionally be seen playing a Gibson ES-335 Semi-Acoustic guitar, as at the Bonnaroo music festival:

He plays often this guitar, even if it's not his main guitar, you can see he plays with this guitar in many live songs.

According to Collings artists page Mumford plays a C10 in Sunburst. In the picture he can be seen with one on stage.

Marcus was on the hunt for a new (to him) Fender Telecaster, something with some Springsteen vibe. After picking and playing several iconic teles, he stumbled across this really unique piece that just found its way to Chicago Music Exchange two days prior. It’s a 1967 Fender Telecaster in a blonde finish. What really sets this guitar apart from the others is the modified pickup in the neck. The original pickup was replaced with a vintage Gibson Patent Number pickup that really gives this guitar a screaming rock n’ roll sound.

Marcus uses this guitar a lot on Wilder Mind and it joined him for all of the Wilder Mind tour.

In the video for "Little Lion Man" the Yamaha F335 is present the entire time in Marcus' possesion.

In this video, Marcus can be seen playing a Collings D3 dreadnought at the One Love Manchester concert. The Collings D3 dreadnought has a similar design to the Martin D28, and Marcus began using it back in 2011 interchangeably with his Martin D28 (Likely multiple D28s). At the 2011 Grammy awards, Marcus played his Collings D3 during Mumford & Sons' live performance of The Cave.

2 different Super Reverbs

His choice for guitar amp used to be a Fender Hot Rod DeVille (especifically, the Hot Rod DeVille 410)

On the pedal board there's the GigRig G2.

Marcus Mumford posted a pic on instagram with a neat pedalboard infront of him. I think one of those pedals might be a blue sky. Can you identify the others?

He uses either a Beta or Sm58 for live performances

He uses either a Beta58 or SM58 E.g. 40:50

in this photo we can see mark playing a guitar with g7th capo

In this concert at the Reading Music Festival, Marcus Mumford uses the Fishman Neo-D Humbucking Acoustic Pickup. As one can see, the device is drilled over his sound hole (the black bar going across it). This picks up the acoustic sound and makes it sound much better and clearer.

In this photo, Marcus Mumford of Mumford & Sons is playing his Gibson F5-G Mandolin.

At the reading festival 2015, Marcus used a triad-orbit advanced mic stand. Enable him to easily switch between his instrument setup without changing it. When playing electric guitar, he does not use the kickdrum. However while playing the acoustic, he does.

The connection between the mic and the stand itself is a Triad-Orbit "micro 2" adapter.
