What is it? Possibly, if you’re a guitar player, it’s the best place imaginable.
It’s where you want to spend all of your time when behind the neck of your favorite guitar. Bond with your guitar!
The weight, the girth, the neck, the action, the balance and built in curves influence your guitar comfort zone.
Sometimes you play a guitar and instantly it’s a joy to play. Feel is most important, more so than any other aspect of your instrument.
As builders, we can assemble the finest materials and mate them in the best ways possible, but if a player doesn’t enjoy the feel then nothing else really matters.
A guitar needs care from the moment it’s produced to the time it gets to you.
The body and neck must work well together. All other parts must be in harmony with each other.

Comfort mods include, tummy cuts in the back of the guitar for better more ergonomic fit with the human body. Because the cut makes the guitar body fit the human body closer.  The feel is softer with comfort curves that feel more natural to us.  Other comfort issues include smaller and thinner guitar necks. In addition players with medical issues such as tendonitis, we work with them. Guitar neck shaving is done to slim down the neck for ease of play. Other comfort mods have to do with a guitar players hand size, and reach on the “heel crest area of the neck”.

These mods help a player feel more comfortable

Still other guitar comfort mods include slimming down the general thickness of the neck, the width of the neck, radius or curvature of the top of the fret board,  height of the strings from the frets, the scale length of a neck, string gauge,  certain afflictions like arthritis, may have an effect on the location of the volume and tone controls.  This affects the feel of the distance of the strings from each other.  Areas as neck back contours can be very influential to a players comfort.  Because all of these mods help a player feel more comfortable.  And therefore they are more able to concentrate on the job of playing music.
As a guitar player you’ll need:

A well balanced guitar with light weight that you can play all night long.

Body contours in the right places, especially where your right arm lays.

Volume control is easy to manage while playing. One that retains the highs when dropping or rolling off the volume

A bridge that is comfortable to handle while palm muting

The strings are close to the frets board making it effortless to play the guitar.

Easy to grip neck with the right feel to make holding it a joy

Your Comfort Zone

When it comes to bonding with a particular guitar it needs to exactly strike your comfort zone at first touch. Nothing else really matters unless the guitar plays and feels great.
