Shubb Capo Royale vs G7th Performance ART: A Comparative Review

My quest for the perfect capo continues. I search because the two primary problems with capos still exist: string buzz a loss of tune upon application. A few months ago my first capo review involved a comparison of three G7th capos: G7th Nashville, G7th Performance, and G7th Performance 3 ART. String buzzing when a capo is applied was the problem addressed. The G7th Performance 3 ART makes the claim that its Adaptive Radius Technology provides “…buzz-free use.” The claim was held up when compared to the other G7th capos. With G7th’s most recent product, there was only one buzz recorded which contrasted to multiple buzzes with two other capos made by “The Capo Company.” The string buzz contest was settled, in this posting maintenance of tuning is addressed. Two capos which boast the ability to keep your guitar in tune when applied to the fret board are compared this day: the Shubb Capo Royale, and G7th’s Performance 3 ART.


Let’s begin with the claim set forth by G7th:

The Performance 3 is the culmination of years of designing, tweaking, and improving — but most importantly, listening to guitarists and their views on what a capo SHOULD do. Now, coupling our Unique Tension Control system with the ground-breaking ART [Adaptive Radius Technology] string pad mechanism gives a near-perfect capo experience.
The ART system within the top bar of G7th Performance 3 capos adapts to the true curvature over your strings and fretboard, exerting completely even pressure across all the strings — setting a new standard of in-tune, buzz-free use. It gives you the maximum tuning stability with the minimum possible tension in EVERY position, on ANY guitar neck.

Next, we have the Shubb claim:

The Shubb Capo is designed to reduce tuning problems. Its custom material presses the strings just like your fingertip. Its unique design closes onto the neck just like your hand. Its pressure is totally adjustable. The result: no retuning is necessary.

Similar claims, but will there be similar results? I put the capos to the test on five different guitars using one Snark electronic tuner. All five guitars were tuned (standard tuning) using the Snark tuner. Then, each capo was placed on frets 2, 5, and 7 on all five guitars. Each guitar was retuned before repositioning each capo at the above mentioned frets. “Distuning” was noted for each capo at each position by the number of “minute” increments (flat and/or sharp noted by -1, or +2, for example) from the “12 o’clock” position on the tuner. Here are the results in terms of total “distuning minutes” at all three fret positions (again 2, 5, and 7).

Breedlove Pro Series D25/SRH acoustic dreadnought:

Shubb: +9 (all sharp), G7th ART: +6 (all sharp)

Faith FG1RE PJE acoustic dreadnought:

Shubb: +20 (all sharp), G7th ART: +10 (all sharp)

Yamaha A5R ARE acoustic dreadnought:

Shubb: +13 (all sharp), G7th ART: +16 (all sharp)

Taylor Grand Pacific 317e acoustic dreadnought:

Shubb: 0, G7th ART: +4 (all sharp)

Ibanez Talman Prestige solid body electric:

Shubb: +4 (all sharp), G7th ART: +9 (all sharp)


Shubb: +46 minutes sharp, G7th ART: +45 minutes sharp

Subjective winner

In conclusion, I was pleased with the tuning stability provided by both capos. I will NOT run the results through a Chi Square statistical analysis, but I would guess by the results there would be no statistical difference between the two. Further, the minor distunings at all five fret positions would not be audibly noticeable to the vast majority of players except, perhaps, to someone blessed with perfect pitch. My experience with tuning issues with other capos allows me to express the opinion that both capos live up to their respective claims. However, I would give the Shubb Capo Royale the nod given its price of $20.85 (Amazon) compared to the G7th ART’s price of $49.99 (Amazon). Plus, with its slim gold-plated presentation, the Shubb just looks cooler!

Keep on playing!
