Bolt-on Neck x Humbucker Models【Bacchus Global＆Universe Series】

In this article, we’ll go into detail about “bolt-on (detachable)” and “humbucker” models of the Bacchus brand, see some of the advantages and disadvantages of both of them.

What exactly are “bolt-ons” and “humbuckers”?

Advantages and disadvantages of bolt-on models

Bolt-on (detachable) refers to a specification in which the neck and body of a guitar or bass are bolted together.
There are two major methods of bolt-on joints: a metal plate called a neck plate is placed between the two and secured, while a heel-less cut is made to allow smooth access to the high frets, so the plate is eliminated and the bolt is secured to the body itself.

Advantages of bolt-ons

・Sound: Bolt-ons tend to have a punchy sound with a strong attack.
・Flexibility in body shape: Bolt-ons are easier to maintain than set necks (where the neck and body are not detachable), and are also easier to replace than set necks, making them suitable for mass production. Many standard guitar body shapes use this bolt-on design.

Disadvantages of bolt-ons

・Sound: Since the neck and body are bolted together, the transmission efficiency of string vibration is limited compared to a set neck, where the neck and body are in close contact. As a result, the sustain tends to be shorter than that of a set neck.

Features of humbucker pickups

A humbucker is a pickup consisting of two single coils wired together. There are two main types of humbuckers: a single coil pickup with two single coils in a row, and a “covered” pickup with both single coils covered by a metal or differently shaped cover.

Feature 1: Resistant to noise!

A major feature of humbuckers is that the coils are connected by wiring that reduces noise. This produces a clearer sound than a single coil. This specification is useful not only for amplifiers but also for DTM creation, which is becoming increasingly popular these days.

Feature 2: Thick and powerful sound that works well with distortion!

Humbuckers have a higher output than single coils and are characterized by a thicker, more powerful sound with an emphasis on the lower midrange. They also work well with distortion effectors and are especially useful in genres such as hard rock and metal.

Feature 3: Extended sustain!

Humbuckers, with their higher output and greater sound energy, can transmit string vibrations more firmly to the output end, allowing the sound to last longer.

They are perfect for those who want the benefits of humbuckers: noise reduction, high output, sustain, and a choice of standard body shapes.
The Bacchus Universe Series is an entry-level guitar lineup with a familiar electric guitar body shape and a relatively affordable price range, so they make for a very good option as your first guitar or second guitar. It is also available in the entry-level Bacchus Universe Series lineup at a relatively affordable price.

TAC24 and IMP24 models with coil tap and 24 frets for a wide range of expression

These models are equipped with a “coil tap” function that allows the single coil of the humbucker to be operated independently. The TAC24 has a TL-type body shape, while the IMP24 has an ST-type body shape.
Humbuckers are characterized by a round, powerful sound with more bass, but by using the coil tap switch located between the volume and tone knobs, it is possible to produce a crisp single-coil sound.

※The model in the image is “TACTICS24-FM/RSM”, but the coil tap works in the same way

The “24” in the model name indicates that the guitar features 24 frets, making it adaptable to technical playing styles on high frets. The bridge is also equipped with a two-point tremolo unit, which allows for arm-up-and-down playing.
The TAC24 and IMP24 models allow for a wide variety of sound creation, expanding the range of expression of the player.

Many models to choose from, 24 TACTICS models

The “TACTICS24” model is part of the Bacchus Global Series, a lineup that’s higher in quality than the Bacchus Universe Series. Compared to the TAC24 model, the TACTICS24 model has upgraded parts such as the nut, frets, and bridge.
The current TACTICS24 models in the Global Series are available in a total of 4 models and 18 colors.

Bacchus Japan Tune-up Series

The TACTICS24 models in the “Japan Tune-up Series”, the Series that’s above the Global Series, are characterized by the use of quilted maple and other woods often reserved only for high-end models for the body top. The TACTICS24 models are available in a total of four models and a total of 11 colors, ranging from walnut and other woods with a subdued appearance to spotted and burl woods with a striking look to them, further increasing their individuality.

The two series together offer a total of 8 models and 29 color schemes to choose from, providing a wide variety of options.

Bacchus Global Series “BARON” models with beautiful curves of the arch top and TL type body shape

The “Baron” models in the Bacchus Global Series lineup are characterized by their body shape. While following the standard body shape, the “BARON” models are one-of-a-kind guitars with a swooping “archtop” body top!

The variations of its derivatives, such as the “BARON-JAZZ” model with a hollow body structure (a structure that gives the guitar a more acoustic sound by creating a cavity in the body), are also noteworthy.
It may not be an exaggeration to say that this model, which is novel while following the body shape and structure of previous guitars, produces a sound suitable for the future of music making.

But are “bolt-on” x “humbucker” guitars practical specs? Are artists actually using them? In fact, we have already released a signature model by an artist. Here it is!

Bacchus Global Series – Yome to Ore’s Marco signature model: GIN-FORCE

The husband-and-wife unit “Yome to Ore” has attracted many people with their solid playing skills and has over 400,000 channel subscribers on YouTube as of 2025.
The signature model “GIN-FORCE” of the husband, guitarist “Marco”, who colors the music with his lead playing, is also a bolt-on type with humbucker specifications.

We are also certain that the specifications are practical, as many accomplished artists use them on stage and in performance videos.

If we can help the player express himself, that’s mission accomplished!

We have introduced various “bolt-on” x “humbucker” models from our Bacchus brand.

But at the end of the day, a guitar is just a companion that makes the player shine. It would be a great pleasure for us if our guitars could enhance the charm of the player. That is what is most important.

For that reason, we have a variety of models for you to choose from!
Please enjoy your favorite bolt-on x humbucker combinations!
