Types of Guitars Used and Features
Yoshinobu Ohga’s guitar collection demonstrates both tonal diversity and adaptability to different performance contexts. His mainstay instrument for many years has been the Gibson Les Paul Standard. With its thick, powerful tone and strong sustain, it naturally complements the heavy, hard-driving sound of B’z. In songs like “ultra soul” and “RED,” the punchy distortion tones owe much to the Les Paul Standard’s strong midrange character.
During the “B’z LIVE-GYM 2015 -EPIC NIGHT-” tour, Ohga expanded his lineup further, preparing multiple Les Paul models including the Les Paul Custom and a ’58 Reissue. These instruments were carefully selected to handle different tunings and tonal needs, allowing him to switch guitars mid-set depending on the musical context. The Custom provided a darker, smoother tone, while the vintage reissue brought a rawer, more open midrange texture.
In acoustic sections, Ohga frequently uses a Taylor 814e, which offers lush resonance and sparkling overtones. This guitar has been featured in ballads like “Kimi wo Kinishinai Hi Nado” and “Exit To The Sun,” where its natural projection and clarity suit intimate arrangements. Backup models from the Taylor 800 series have also been spotted on stage, showing his preparation for unexpected live situations and ensuring tonal consistency across performances.
A Fender Custom Shop Stratocaster has also been part of his arsenal. This guitar was chosen for its bright, sharp attack and the kind of crisp high end that works perfectly for tracks such as “Black Coffee” or “EPIC DAY.” Compared to the Les Paul, the Stratocaster provides a contrasting tonal option with more articulation and presence in the upper registers.
For songs requiring alternate tunings or dramatic stage visuals, Ohga has used a double-neck guitar made by Diamond. This instrument was notably employed in “RED,” where one neck could handle standard tuning and the other a half-step down, allowing instant transitions between parts without changing guitars mid-performance. The striking look of the double-neck also adds stage impact, underlining Ohga’s flexibility as a performer.
All of these choices reflect his role as a support guitarist for diverse acts such as B’z, ZARD, and Mai Kuraki. Each guitar is selected not for flash but for functionality, enabling Ohga to cover a broad musical spectrum. His instrument lineup showcases his deep understanding of tone, as well as the professionalism required to adapt to different artists and live situations. These selections are believed to represent the backbone of his guitar setup across tours and recordings.

Tone Settings, EQ, and Mixing Approaches
One of the most distinctive aspects of Yoshinobu Ohga’s tone design is his ability to adjust the midrange so that his guitar always finds space in a dense band mix. This is especially crucial when supporting B’z, a band known for its loud, information-rich arrangements. Ohga’s guitar rarely gets buried in the mix, even when competing with Tak Matsumoto’s powerful lead guitar and full instrumentation. His method is not just about volume but about choosing the right frequency range and controlling dynamics naturally through playing touch.
For distorted sounds, Ohga typically sets the FAT13’s gain at around 5 to 6, balancing saturation with clarity. Rather than maxing out gain, he relies on guitar volume control and picking dynamics to shape nuance. Treble and presence are slightly boosted, ensuring that his tones occupy a distinct frequency range without overlapping Matsumoto’s guitar. This approach makes his playing supportive yet audible, whether he is laying down rhythm chords or stepping out briefly for fills.
On the clean side, the FAT12’s EQ is set with restrained mids and smooth highs. This preserves the natural resonance of Taylor acoustic-electrics and the clarity of Fender Stratocasters. For live settings, PA engineers often apply light compression to the midrange, helping his clean tones remain articulate without sounding squashed. This setup allows acoustic guitars to cut through in large arenas while still sounding natural and musical.
Effect programming is also a key part of his tone strategy. With the MS-3 and ML5, Ohga pre-programs patches that activate delay or modulation effects at precise song sections. His delays are often tempo-synced, using quarter-note or dotted-eighth settings to enhance rhythmic precision. Subtle chorus or flanger effects are employed only when needed, adding dimension without overwhelming the arrangement. His discipline in avoiding unnecessary effects highlights his philosophy of serving the music first.
Signal routing is carefully optimized to preserve clarity. Wherever possible, he avoids long chains of serial connections that could muddy the tone. For acoustic sets, Nova Delay and Nova Reverb are placed on a dedicated signal path and sent directly to the PA as a clean line, ensuring maximum transparency. For electric sets, his routing balances between front-end drive pedals and effects loop integration, minimizing signal loss while maintaining tonal integrity.
In the overall band mix, Ohga’s guitar is often panned slightly right, leaving room for Matsumoto’s guitar on the left and vocals in the center. EQ adjustments by the front-of-house engineer typically emphasize the 2–4 kHz range for articulation while reducing overlap with keyboards and backing instruments. This careful placement ensures that Ohga’s contributions are always felt as part of the ensemble rather than clashing with lead elements.
Another critical factor is dynamics. Ohga’s playing integrates with compression and EQ rather than fighting against them. Instead of relying on heavy outboard processing, he achieves dynamic balance through consistent picking and guitar volume adjustments. This “player-driven compression” produces a natural feel that translates well across different venues and recording situations.
Ultimately, Ohga’s tone settings are not about spotlighting himself but about enhancing the total sound of the performance. His use of EQ, gain staging, and mix placement reflects a philosophy of balance and precision. Whether shaping crunchy rock riffs for B’z, delicate cleans for ZARD, or atmospheric textures for Mai Kuraki, his approach demonstrates professional-level awareness of how guitar fits into the bigger picture. These methods are believed to be central to his consistently reliable tone, regardless of stage or studio environment.
Affordable Alternatives to Recreate the Tone
Reproducing Yoshinobu Ohga’s professional guitar system in its entirety would be unrealistic for beginners or hobby players, given the boutique-grade amps, custom pedals, and rack-based switching systems he employs. However, it is possible to approximate the essence of his sound using more affordable and accessible gear. By focusing on the tonal characteristics that define his style—clear cleans, punchy midrange distortion, and tasteful use of spatial effects—you can get remarkably close without investing in prohibitively expensive equipment.
For the amplifier, boutique FAT amps are difficult to obtain and costly, but the BOSS KATANA Artist MkII is an excellent substitute. It delivers versatile clean tones with ample headroom and smooth overdrive that captures the essence of Ohga’s balance between power and clarity. Its integration with multi-effects pedals makes it particularly suitable for those looking to recreate Ohga’s flexibility at a fraction of the cost.
When it comes to effects, the BOSS MS-3 stands out as a practical and affordable centerpiece. Combining a switcher and multi-effects unit, it allows you to replicate Ohga’s workflow of blending core drive sounds with modulation, delay, and reverb. This single unit can cover many of the essential textures found in his live rig, making it one of the most cost-effective ways to begin.
For additional boost and solo projection, a compact pedal such as the Ibanez TS Mini or Xotic BB Preamp provides midrange focus and sustain, similar to what Ohga achieves with boutique boosters like the Ovaltone Harmonics Boost. These pedals excel at cutting through dense mixes, ensuring solos remain articulate and dynamic.
On the spatial side, while Eventide’s H9 is a high-end solution, more budget-friendly pedals like the NUX Atlantic Delay & Reverb offer rich time-based effects in a single compact unit. The Atlantic even supports dotted-eighth delay settings, a common feature in Ohga’s live tone, allowing guitarists to approximate his delay-driven textures at a much lower cost.
For acoustic guitar players aiming to mimic his Taylor 814e tone, the Yamaha A5R or Taylor Academy Series are viable alternatives. While they cannot fully replicate the harmonic complexity of the 800 series, they deliver warm resonance and solid projection at a beginner-friendly price point, making them excellent choices for singer-songwriters or support guitarists.
Finally, supporting pedals like the KORG Pitchblack X tuner and BOSS FV-30H volume pedal complete the system. These affordable units replicate the tuning stability and expressive control of Ohga’s more elaborate live rig. Together, this collection of alternatives allows players to recreate a simplified but effective version of his setup in the 50,000–80,000 yen range (roughly $400–600 USD), making it accessible for aspiring musicians.
