Mark Potter

We have these on 'Grounds for Divorce'. National Resolectrics, which sound amazing. Incredible.

— Matt Skinner, Elbow's guitar tech

From this 2011 interview with Music Radar:

The album's finished now, but that doesn't stop them from tweaking the songs for the road. As they work their way through set closer, The Birds, it's Mark's bluesy slide riff (played on a National Resolectric) that resonates across the room, in contrast to the recording.

From this 2017 interview:

You hear this at the beginning of ‘Kindling’. I played the riff that we then looped to create the track, but forgot to tune it. So when we came back to the track, it made everything that little bit more fun. We tried to retune it in mixing but it lost all of the character, so in the end we decided to go with the original recording and live with it. If you’re being really precise you might hear it but the vibe of the tune was what we needed. That’s something that applies throughout the album, really.

Guitarist Mark Potter from the UK alternative rock group Elbow plays the Godin Montreal, enjoying its smooth tones and versatility.

Additionally, in this TC Electronic Gear Run for Elbow's Northside Festival 2011 set, guitar tech Matt Skinner states that Potter was using the only two existing prototypes for a Montreal. Skinner also states the Potter only used the acoustic output. Potter himself elaborates in this article:

I started using them about five or six years ago. They have an acoustic output and an electric output and the electric sounds as good as my ES-335.

I'm in talks with Godin about making a signature guitar. It will be somewhere between the Montreal and the 5th Avenue. It's still very early days, but I'm hoping that the next time I'm in the studio, I'll have a guitar with my name on it!

"My workhorse guitar. It’s the first guitar I always plug in when I’m looking for a sound. I’ve played it for so many years that I know what I can get out of it most of the time. I’ve had this one for about eight years. The first Elbow album it’s on is Leaders Of The Free World, and it’s been on every subsequent album."

"It’s a reissue of the one that George Harrison used to play which I got as we were coming to the end of recording The Take Off And Landing of Everything. It’s such a lovely guitar. Aside from tone it has this wonderful dampening system operated by levers, and it gives you a great muted sound."

In this other interview with MusicRadar, Potter stated the following about the recording of Elbow's "Grounds For Divorce":

It was a Gibson Les Paul through an Electro-Harmonix Big Muff pedal and then I used a '54 Vox AC30 head with a vintage Marshall 4x12 cab. It's not like I thought 'I'm writing a rock riff, therefore I must use a Les Paul'. My favourite guitar is a Gibson ES-335, but I played it on that and it didn't quite have the sort of crunch that I was going for, so as soon as I picked up my Black Beauty Les Paul, that was it - it sounded great. Originally I just recorded the one riff and then I thought 'Well, how about if I track it two or three tones up the octave?' Then I did down the octave and then I played it on a bass, bending the note on that as well. When we twinned these four or five signals of the same riff played in five places on the guitar, it just sounded massive.
