Personalised multi-point setup included

Before dispatch, your instrument will be treated to a full setup. That's not a quick tweak, but a full multi-point setup by an experienced guitar technician who will check and adjust every single thing on your guitar, bass, ukulele or banjo to ensure it is performing at its absolute best.

This is not a quick process but we believe every instrument should go through our process to acheive an exacting standard of playability.

Frets

We start with the frets on your instrument. All guitar necks move and change over time so we will make sure that your frets are nice and flat as we go up the neck. We don't want any high or low spots as this will mean your guitar will need a higher than optimum action and potentially suffer with fret buzz.

We check and properly profile the playing surface of the frets and then make sure the fret ends are finished off properly. The fret is then polished to ensure smooth string bending.

Truss Rod

Then it's on to the truss rod. This metal rod differs from guitar to guitar (some guitars such as classical guitars don't usually have a truss rod!) and basically controls the "relief" or curve of the neck. Not enough relief and your strings won't have enough clearance over the other frets when playing. Too much relief and you'll have a high action which gets worse as you go up the neck.

The heavier the strings then the more the truss rod needs to work. Proper adjustment in the workshop means that the action will be just right for the strings fitted to your guitar.

Top Nut

The top nut is super important and is one of the two open contact points of your guitar. The technician will check and cut each slot to make sure the strings both run freely but are not sitting in a slot that's too big.

The top nut also plays a big part in the action of your guitar so we'll hit that sweet spot between too low and too high.

Saddle(s)

Another really important part of your guitar!

On an acoustic, the saddle is cut to the correct height making sure the bottom is 100% flat and straight. This means the string can transfer its vibration properly into the body of your guitar.

For electric guitars, the saddles are adjusted to ensure your intonation is perfect. We will also match the saddles to the radius of your fretboard.

Bridge / Tremolo

The bridge affects the break angle and string height of your guitar and is also responsible for holding your saddles.

For a guitar with a Floyd Rose tremolo system or similar, the spring tension has to be just right to allow the tremolo to return to its "zero point" and keep everything in tune.

For guitars with standard tremolos, we can set it to float and be used both up or down like a true tremolo or we can lock the trem block back so the tremolo will only go downwards.... the choice is yours!

Intonation

Intonation is the measure of how in-tune the guitar string is across the length of the fretboard and a guitar with badly set intonation will get more and more out of tune as the string is shortened when you play.

Tiny adjustments are made to each string where applicable to adjust its length and ensure that the intonation is set just right.

Overall Action

Once all the above has been completed, the guitar is checked for playability and fine adjustments are made. This step brings everything together and means your guitar will be set up optimally.

Machine Heads

Every machine head is operated and checked for function. We need to ensure that the machine heads operate smoothly.

Electrics

All the functions of your guitar are checked to ensure everything is working as intended.

For acoustic guitars we will check the functions of the EQ system and controls as well as check the internal cabling and jack socket.

For electric guitars, all the pickups are checked for function and tonal response. All controls and switches are operated to ensure they are functioning properly. The jack socket is checked.

Other Parts

All other parts such as strap pins, bushings, tuning buttons etc are fully checked.

Dispatch

All our instruments get the same premium treatment whether you purchase online or instore.

If you have purchased online, your guitar will be carefully packed ready for dispatch. You will receive a tracking link via email.

Happy playing :)

Description

The NF ACOUS NM20 IEM is a professional in-ear monitor built as a full upgrade from the classic NM2, aimed at live performers, studio musicians, and audio engineers who need accurate, uncoloured reference sound. Pairing an MC2L-100P dynamic driver with patented Clutter Trap acoustic technology, it focuses on clean transient detail, controlled resonance, and reliable comfort during long sets or sessions.

MC2L-100P Driver and Clutter Trap Acoustic Technology

At the core of the NM20 is the upgraded MC2L-100P dynamic driver, working alongside NF ACOUS's patented Clutter Trap system to damp unwanted internal resonance and sharpen tonal accuracy. The result is a transparent, natural monitoring profile across a 9 Hz to 40 kHz frequency range, with distortion kept under 1%.

Rated at 32 ohms with 108 dB/mW sensitivity and a 125 dB maximum SPL, the NM20 handles demanding stage feeds and high-output headphone amplifiers cleanly while retaining fine detail.

Lightweight Construction and 25 dB Noise Insulation

The outer shell combines high-strength polycarbonate with metal accents, keeping the earpieces light in the ear while standing up to regular gigging and studio use. A snug fit provides 25 dB of passive noise insulation to cut down stage wash and room bleed, helping you monitor clearly without pushing volume levels.

Secure 2-Pin Connection and Supplied Accessories

A redesigned 0.78 mm dual-pin socket holds the included 5N OFC cable firmly in place during active stage movement. In the box, you get six ear tips across MS, S, M, and L sizes to dial in a proper seal, a 3.5 mm to 6.35 mm adapter for mixing desks and interfaces, and a protective storage box.
