Personalised multi point setup included

Before dispatch, your instrument will be treated to a full setup. Thats not a quick tweek 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.


We start with the frets on your instrument. All guitar neck 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 theis 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.

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 must 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.

Top Nut

The top nut is super important and is one of the two open contact points of your guitar. The tech 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.


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 form the correct radius to match that of your fretboard.

Description Reviews Questions

The Sigma DM7E is a 7-string electro acoustic guitar that features an additional paired octave G string for a fuller, 12-string like voice.

Many guitarists like the idea of having an 12-string acoustic, but for many the playability and idea of keeping 12-string in tune can be a little off putting. Sigma have come up with an ingenious solution with this DM7E. By adding one extra string, an octave of the G, the DM7E is able to achieve something of the sound of a 12-string without having every string paired.

The body of the DM7E is a standard dreadnought size and shape, constructed from mahogany for the back and sides, paired with a solid Sikta spruce top. Married to the body is a 25.4" scale mahogany neck, with a comfortable low profile neck profile, that is topped with a micarta neck. 

With the addition of an onboard preamp (wth tuner) and undersaddle pickup, amplifying the DM7E is a breeze - great for studio and live work.

Other appointments include bone nut and saddle, and chrome diecast tuners.
