Model S

NK Forster Model S – Designed to be heard, wherever you’re playing.

Refined. Balanced. Responsive to the way you play.

WHAT IT IS

The Model S is a hand-built steel-string guitar, shaped like a Martin OM or OOO but with a tighter waist that gives it sharper focus and tonal clarity. Whether you play with fingers or a pick, this design adapts to your touch. The Model S-SS has a pronounced mid range response, the S-HO, a little more bass. It’s the most versatile model I offer, built with your input from the ground up.

WHY YOU NEED IT

You’ve outgrown factory guitars or even luthier made guitars that sound generic.
You want a voice that feels like yours. Focused, alive, expressive.
The Model S gives you a refined response across the spectrum, whether you’re picking softly or digging in with a pick.

It started as a minimalist build. But the shape delivered so much clarity and balance, it became the foundation for something far more evolved.

WHAT YOU GET

A fully custom Model S, tailored to your playing style.
Choice of tonewoods selected for tone, feel, and look.
Two soundboard designs available: S-SS and S-HO.
A lifetime warranty.

WHY IT’S WORTH IT

Every instrument is built by me – no production runs, no shortcuts. Each design has been refined through years of feedback from professional players who rely on their instruments night after night.

You’re not just buying materials and labour; you’re buying the sound, playability, and longevity that come from over three decades of experience.

The Model S has been my main guitar for the last decade. It’s a constant source of inspiration for me. Without Nigel’s guitar, I don’t think I would have ever recorded a solo record, they have incredible tone and give me so much confidence, making me a more fluid player.

The Model S has unrivaled versatility. I have used it in every session I’ve ever played, it triumphs in every style including old-time jazz, pop rhythm overdubs and open-tune fingerstyle. I’d truly be lost without it.

Nigel's 14 fret to the body, single cutaway steel string has impeccable tonal separation and sustain. No blur; each string sounds as though it's on a separate audio track. The guitar is over 10 years old and has aged into nuance - it is as responsive as a great classical guitar. If you play fingerstyle guitar, this is the kind of precise and lovely instrument you want.

- David Hartman, USA
I have 2 guitars from Nigel, a model F that I bought in 2007 and a model S of 2010.

To me, they continue to be an endless source of joy and inspiration. The workmanship is second to none. The sound is just breathtaking. Take my word for it. Clarity, separation, sustain to die for; the sweetest trebles you’ll ever hear, a midrange full of presence, and bass strings just as strong as necessary; the result is a well-balanced overall sound across the fingerboard. It just doesn’t get any better.

Like all true works of art, Nigel’s guitars are unique. You can’t really compare them to anything else out there. In my view, this sets Nigel apart from many other world-class luthiers many of whom sound somewhat similar. It seems that Nigel has never followed anyone else’s (not even Sobell’s) footsteps. He’s always been doing his own thing.

But most importantly: After all these years, I still get goosebumps when I pick the guitars up and play the first chords. No kidding. I can’t think of a better reason on which to base my recommendation of Nigel’s work to anyone seeking his life instrument.

- Alex Hanslik, Austria
The Model S is an ideal guitar for the studio - some guitars have a narrow ‘sweet spot’ where the sound is balanced and strong in every register - the Model S has a super wide sweet spot and will give a huge number of tonal options depending on microphones and room acoustics. It simply sounds great wherever you’re stood, always.

Ian Stephenson, England
Some seemingly simple design ideas combine into the best guitar I’ve played, bar none - genius - it’s constantly inspiring, and it’s changed the way I play for the better.

Gavin Davenport, England
I've had my NK Forster for 5 years now and it's the best guitar I've ever played. Solid, resonant
It's my number 1 live and recording guitar. The tone and sustain are unique and the craftsmanship is top tier.
