VoteIs The Ibanez GRG121SP Easy to Play?
The Ibanez GRG121SP meets 5 out of our 8 criteria items for beginner friendliness, which means that it's a good guitar to start with as a complete beginner. This takes into account the type of frets, scale length, nut width, bridge type, fretboard radius, and neck profile to determine the easiest combination for new players to get used to.

- Comfortable fretboard
- Short scale
Hand Size Comfortability
After taking into account the neck profile, scale size, fretboard radius, and nut width, we can conclude that the Ibanez GRG121SP's construction favors people with relatively small hands.
Nevertheless, this comes down in the end to personal preference. Make sure you test this guitar—or another one with similar characteristics—before buying.
How Lightweight is it?
We found that the Ibanez GRG121SP weighs between 6.75lbs (3.1kgs) and 7.6lbs (3.4kgs). This was recorded from some online retailers that publish the weight of the guitars they sell.
Scale Length
Scale length is the distance the strings will span between the bridge and the nut. It can tell you a lot about the overall playability and tone of the instrument. A longer scale length means longer distance between frets, brighter tone and more string tension—which means lower action, but more difficult bending of the strings.
Here's the Ibanez GRG121SP's 25.5" scale length compared to other common sizes:

This is the same scale length used in Stratocaster guitars, and it's one of the main reasons they have such a bright sound. It's considered a long scale when compared to most non-baritone guitars.
Since the distance between bridge and nut is relatively long, you'll need to give the strings more tension to get them in tune. This higher tension will allow for a couple of things. First, you can get a lower action (get the strings closer to the fretboard) because the strings won't 'wiggle' too much when pluck and won't cause fret buzz. This can allow you to use lower tunings without increasing your string gauge, and it will make it easier to press down the strings fast.
However, the frets will also have a wider separation between each other, which can make it harder to play, especially if you got small hands. The higher tension will also make the strings feel stiffer, so bending will require more strength.
Neck Profile

The neck profile tells you the thickness (neck depth) and shape in cross section. Every difference will completely change the feeling and comfortability of the neck. This is a highly subjective thing, but most players indeed prefer certain types of necks (like Cs and Ds) because they feel nice in most hands.
The Ibanez GRG121SP's neck thickness is approximately 0.77'' (19.6mm) at the first fret, and 0.85'' (21.6mm) at the twelfth.
These measurements were taken either from the official Ibanez website, or, in case this information wasn't provided, by researching multiple online marketplaces and forums where owners of this model have posted their measurements.
It has a GRGR type neck. This neck is used mainly in Ibanez's mass production guitars, and it's very similar to the Wizard profile in terms of shape and thickness. It's thinner than the C profile that most people prefer. The idea is to give players the least interference from the neck when playing fast. It's the type of neck that shredders love. However, some people might prefer a thicker neck that allows them to wrap their hands around it for resting while playing.
Fretboard Radius
When it comes to fingerboard radius, personal preference will dictate which one is better for you. However, most people seem to agree that a more curved (lower) radius will make it easier to play chords while a less curved (higher) radius is better for soloing and bending.
The Ibanez GRG121SP has a 15.75" fingerboard radius. Here's an image comparing this guitar's fretboard radius to other popular choices:

It's a radius that makes playing single notes (and bending, vibrato, sliding, etc) easier than on a classic Les Paul guitar. However, it's still more curved than some baritone and 7+ strings guitars.
Compound radius fingerboards give the best of both worlds. Unfortunately, the Ibanez GRG121SP has the same radius across the board.
Playability compared to main competitors

Nut Width

The Ibanez GRG121SP has a nut width of 43mm (1.693''). This size is also known as 1 11/16'' and it's the most common size. It offers a good balance of string separation at the nut. It's the size that most guitarists prefer as it gives them just enough space to play open chords without muting the strings, but without spreading the strings too wide and making bar chords difficult to perform.
Frets
The Ibanez GRG121SP has 24 frets. A lot of people mistakenly believe that having more frets will always be better because it gives you a higher octave. This is certainly an advantage, but there's also a disadvantage to this.
Since the fretboard will be longer, the neck pickup will need to be placed closer to the bridge. And as you may know, the further away the neck pickup is from the bridge, the warmer it sounds. This means you'll have a brighter-sounding neck pickup when using a 24-fret guitar, even if you use the same pickup on a 22-fret guitar.
It comes with nickel silver frets, so they won't last as long as stainless steel frets. If you use your instrument a lot, you might need to replace the frets after a few years. But this is unlikely as most people change instruments before this happens.
Fret Size

Finally, let's talk about fret size. Some people prefer tall frets because it's easier to press the strings and perform bends since there's less friction against the fretboard. On the other hand, some people like shorter frets because they like to touch the fretboard when playing, or because they got heavy hands and tend to press too much on the string and alter the of the note pitch accidently.
The Ibanez GRG121SP's frets are Medium size. With medium frets, you can feel the fretboard more than with jumbo frets, but it's still easier to press the strings cleanly than with small frets; notes might change their pitch just slightly if you press hard on the fret. Also, if you need to do some fret leveling after years of playing, you'll have some room to sand them down without having to replace them.
Playability Score
Does the Ibanez GRG121SP Sound Good? Tone Analysis
Wood will have little influence in the final tone of an electric guitar. Instead, the hardware, especially the pickups, will be the most important thing to look at. Bur first, let's see the quality of the wood.
Wood Used in the Ibanez GRG121SP



Poplar Body: It's similar to Alder in terms of tone as it has a fat low-end with strong mids, but it's a lot cheaper and softer. It's a bit heavier so it's mostly used for tops.
Roasted Maple Neck: Similar to simple Maple, but even stronger, darker, and more stable to temperature changes. This is thanks to the treatment process that consists in using high temperatures to drain the water, sugar, and resins from the wood.
Jatoba Fretboard: It's an exceptionally hard and dense wood that emphasizes the mid-lows, giving a fuller, more round sound than, for example, Mahogany. However, it also has a lot of clarity in the top end.
Pickups
Unfortunately, it doesn't come with pickups from one of the top brands. This doesn't mean you will get bad pickups, but you might want to consider a pickup upgrade after some time.
These are passive pickups, so you can expect a moderade level of hot output instead of the overwhelming output that distinguises active pickups in metal.
The Ibanez GRG121SP's configuration is HH. With this pickup combination, you'll get warmer tones and more output than using single coils. Humbucker pickups cancel the noise that single-coil suffer from, which also results in a warmer tone. This pickup combination isn't only for high-gain music like Hard Rock or Heavy Metal. Their warmness is also popular for Jazz, Indie, R&B, Blues and more.

Versatility
It gives you a good amount of tone options with its 5-way switch. You can use it to choose at least 5 different pickup combinations.
Unfortunately, it doesn't come with more options for coil split or coil tapping. This makes it less versatile than some competitors.

What music genre is the Ibanez GRG121SP good for?
As a 6 strings, Solid Body guitar with HH configuration and Passive pickups, we'd recommend it for genres like Hard Rock or similar. However, you can use almost any guitar for any genre. This is just the typical type of music for this kind of guitar.

How well is the Ibanez GRG121SP Built?
Where is the Ibanez GRG121SP Made?
Knowing where the guitar is produced is a good way to know how well it's built. Some manufacturing countries are known for having higher quality standards. For example, most expensive guitars are made in the US or Japan, but there are some exceptionally great countries—like South Korea—that are building a good reputation.
The Ibanez GRG121SP is made in Indonesia. Many people prefer the quality of an Indonesian guitar over a Chinese. Respectable brands like Epiphone, Ibanez and Schecter are building in this country because of the great quality and lower price. Some people like to compare them to the ones built in Japan during the 80s, when Japanese guitar makers made a name for themselves.
Still, remember that we're taking about Ibanez here, which is a brand with good renown. They know how to use cheap labor in this country without sacrificing too much quality. So you shouldn't end up receiving a useless or ugly instrument.
Bridge
F106: The advantage of fixed bridges is that they don't require any kind of set-up. This makes it extremely easy when changing strings because you don't need to adjust anything besides tuning the guitar. Also, the fact that the bridge is directly attached to the body will help to increase sustain. The disadvantage is the lack of versatility since you can't create the same vibrato effects as with tremolo bridges.
Nut Material
Another important thing to analyze is the nut material, as it's one of the most important aspects that can affect the sound and playability of your guitar. A well-cut nut will make sure the guitar stays in tune and will make it more comfortable to play.
In this case, the Ibanez GRG121SP has a Plastic nut. This is a low-quality nut that you might want to consider upgrading soon. Bone and TUSQ nuts are the best for guitars with a fixed or simple tremolo bridge.
Neck Joint
The neck joint is the part where the neck of the guitar meets the body. There are three main techniques to attach both parts together: Set-In, Bolt-On and Neck-Through. The latter two provide different advantages, although neck-throughs are the most expensive.
This guitar has a Bolt-On neck joint. Even though this type of neck was looked down upon for a long time, nowadays bolt-on necks are well built and provide just as much sustain as any other join method. First of all, it's cheap to make because it consists of simply 4 bolts that attach the neck to the body. And you can travel with the guitar more easily, swap out the neck if you damage it, or upgrade to a more comfortable neck later on.
