RZ Clarinets Conservatory Bb-Clarinet 18/6

I spent several weeks working with the Buffet Crampon BCXXI and immediately felt that this is a clarinet designed with a clear set of priorities - improved low register depth, a more stable high register, and refined ergonomics for the left hand. I approach this review as a player who values orchestral blend and solo flexibility, so my focus was on how the BCXXI performs across chamber, orchestral, and extended repertoire settings.

First Impressions

The BCXXI’s silhouette is subtly unfamiliar - the lower joint is noticeably longer while the bell is shorter, and I noticed right away that the balance in my hands felt slightly different but comfortable, thanks in part to carbon-fiber reinforced rings. Unpacking it felt like receiving a traditional professional grenadilla clarinet updated with purposeful changes rather than gimmicks, and the included rose-gold ligature and two barrels signalled that Buffet intended this as a serious, ready-to-play instrument out of the case.

Design & Build Quality

The BCXXI is built from natural grenadilla and uses Buffet’s cylindrical bore with metal-capped tenons and carbon-fiber wire around key joints - these choices visibly reinforce the instrument without adding bulk. Keywork finish is high quality with silver plating and rose-gold plated pillars/accents, and the key action felt precise and reliable from the start. The instrument comes with GT pads (waterproof and breathable) combined with natural cork pads, which I found sealed well and required no adjustment during my test period.

Playability & Ergonomics

Buffet’s modifications for ergonomics are tangible - the slightly raised D tone hole and reworked key posture for the left hand made certain passages feel less cramped compared with some traditional designs. The added third fingering for middle B-flat is interesting; it opens up fingering choices that can help smooth transitions without register breaks, and I used it often in melodic lines. Thumb rest adjustability is standard, but the overall hand geometry felt like a modern optimization rather than a radical redesign.

Sound & Response

The BCXXI’s defining acoustic change is the extended lower joint with a strategically placed resonance vent - in real playing this gives the low E-flat a woody, present quality I hadn’t expected from a clarinet with a shorter bell. The chalumeau register overall felt more even and the high register was surprisingly stable and easy to speak - I was able to produce clear, consistent high notes without overcompensating embouchure pressure. In ensemble passages the BCXXI blends well while still projecting a focused core when I pushed for a solo line.

Accessories & Storage

The instrument ships with two barrels (commonly 65 and 66 mm), a compact BCXXI-branded case with shoulder strap cover, a rose-gold Harmonie ligature with silver-plated screws, a mouthpiece cap, and a pull-through swab - enough to get playing and to experiment with small adjustments to tuning and response. The compact case is well shaped for the longer lower joint and felt secure for gigging short distances; it won’t replace a large touring case but is perfectly serviceable for daily rehearsal and commute use.

Real-World Experience

I used the BCXXI in a mix of settings - chamber rehearsal, a few orchestral excerpts, and solo practice - and it delivered consistent results. In orchestral seating the instrument sat well within the section and the low E-flat carried without sounding forced. During a chamber rehearsal the flexibility of the mid-register fingering allowed me to negotiate tricky phrasework with fewer register jumps, and audience-facing solos felt authoritative without being overly bright.

The Trade-Offs

No instrument is perfect - the BCXXI’s design adds a new fingering option and altered geometry that may require a short adjustment period for players deeply habituated to a traditional layout, particularly on technical repertoire where muscle memory is critical. The price point places it in the professional bracket, and while I think it delivers acoustic and ergonomic value, budget-minded players might find similar tonal outcomes on less expensive models after setup and adjustment.

Final Verdict

The BCXXI is a thoughtful step forward for Buffet Crampon - it keeps the tonal character and build excellence players expect while introducing targeted physical and acoustic changes that genuinely improve certain registers and ergonomic comfort. I recommend it to advancing students and professional players who want an instrument that offers a modernized approach to the Bb clarinet without abandoning the classic Buffet voice; soloists and orchestral players who prioritize a solid low E-flat and balanced mid-range will find a lot to like here.

I spent several weeks playing the Buffet Crampon Tosca in mopane and came away impressed by how the instrument balances projection, harmonic richness, and responsiveness across registers - it feels like a professional-level clarinet that wants to be heard without demanding constant force from the player. My perspective is that of a working player who moves between chamber, orchestral, and solo repertoire, so I evaluated the Tosca for flexibility, tuning stability, and how it sits under real rehearsal and modest gig pressure.

First Impressions

The first time I picked up the mopane Tosca I noticed the weight and finish right away - mopane has a warm, slightly reddish grain that makes the instrument look as serious as it sounds, and the keywork finish gives it a classy, professional presence. Immediately playable from cold, the instrument felt responsive without a steep break-in; the low F correction key and Eb lever are well-positioned and the adjustable thumb rest made it easy to find a comfortable hand position during long practice sessions.

Build Quality & Design

Construction is excellent - the body and bell in mopane are solidly finished and the tenons have metal caps that give a reassuring fit when assembling the joints. Keywork is silver-plated (with gold-plated pillars/posts on this limited finish) and the blue-steel springs feel lively and precise; the pads are a combination of GT (Gore-Tex style) waterproof pads and genuine cork that should help with long-term reliability and reduced sensitivity to humidity. The Tosca comes with two barrels (65 and 66 mm) and a 'high-tech' protective case that keeps everything well organized and secure.

Playability & Usability

In play, the Tosca is forgiving but articulate - I found articulation crisp without needing overly aggressive tonguing, and altissimo response was accessible when I adjusted my voicing. The ergonomic layout of the 19/6 key system with the low F correction key made alternate fingerings more usable, and the thumb rest adjustment meant I could quickly tweak the balance of the instrument for longer sessions. I did a mix of scales, orchestral excerpts, and a couple of contemporary solo pieces, and the instrument stayed comfortable and responsive through it all.

Sound & Tuning

Sonically, the mopane Tosca sits between warmth and brilliance - the lower register has a rich, rounded core while the upper register opens with clarity and presence that projects well in a hall. I noticed good cross-register consistency - the instrument tends to be relatively stable in pitch when compared to many instruments in its class, though like any wooden clarinet it will require attention to voicing and a slight warm-up period for pitch to settle. The included barrels give useful micro-choices for front-end and response, and I used both barrels in different settings to fine-tune center and color.

Real-World Experience

I took the Tosca to a chamber rehearsal and used it in a small recital setting; in both it cut through an ensemble without sounding thin and blended nicely when required. The high-tech case handled transport to rehearsal and back with no drama and the instrument tolerated typical humidity swings over a couple of rainy days without a pad crisis - the Gore-Tex style GT pads and quality tenon seals helped there. I did have the occasional need for a tiny mechanical tweak (a common thing on any new professional instrument) but nothing serious that kept me from playing.

The Trade-Offs

The biggest practical downside is that the Tosca is sold without a mouthpiece, so you'll need to budget for a mouthpiece that matches your playing style and embouchure; that extra step matters if you want the instrument truly optimized right away. Also, at this level of instrument the price is high and Buffet's quality control can produce variability between individual instruments - I recommend playing several examples before committing, because some players report differences from one instrument to another. Finally, mopane is visually distinctive and not everyone will prefer the color or grain over traditional grenadilla, but sonically it holds up very well.

Final Verdict

The Tosca 19/6 Mopane is a compelling option for the advancing professional or serious soloist who wants a clarinet with a broad palette - it combines a powerful, flexible sound with modern conveniences like GT pads, low F correction, and a two-barrel setup. If you value projection, harmonic richness, and a refined build, and are prepared to choose or invest in a mouthpiece and to play multiple instruments to find the best match, the Tosca in mopane is absolutely worth auditioning.

I spent several weeks playing the Yamaha YCL-CSV R to see how it behaves across orchestral, chamber, and solo repertoire, and I came away impressed by how balanced and focused the core tone is while still allowing expressive color and projection. My use case was as a primary Bb clarinet for rehearsals and small concerts - I wanted an instrument that felt clearly professional out of the case yet responsive enough to shape lines dynamically.

First Impressions

The moment I put the CSV R together I noticed a solid, traditional feel - grenadilla body, well-machined fit between joints, and silver-plated keys that feel substantial under the fingers. The included Yamaha 4CM mouthpiece is serviceable for immediate playing, but I quickly swapped reeds and explored different barrels to fine-tune resistance and color; out of the case the horn is already remarkably well-voiced for a custom-series Yamaha. After an initial week of focused practice I felt the instrument already settling in and responding consistently across registers.

Build Quality & Protection

The CSV R uses seasoned grenadilla for body, bell, and barrel and that density shows up in the instrument's resistance to humidity-related warping and its overall heft - it feels like a professional instrument built to last. Keywork is silver-plated nickel silver with a thicker plating finish, and the threaded posts and blue-steel needle springs give the mechanism a precise, durable action; leather pads are installed for a warm seal that keeps buzzes at bay. The included case is protective and well-padded, with room for the accessories that come with the horn, and the adjustable thumb rest with strap ring is a practical touch for long rehearsals or players who like a strap.

Playability & Usability

From a playability standpoint the CSV R sits in a sweet spot - not too resistant, with enough core resistance to support orchestral lines while remaining flexible for jazz or chamber work; the extended C#/G# key adds a slightly more comfortable reach for some hand shapes. Intonation across the registers is solid - I found small adjustments in barrel and embouchure were all that was needed to lock in tuning, and the hand-tapered undercut tone holes help the upper and chalumeau registers speak evenly. The key heights and touch are well-considered, and after a short setup by my tech the action felt fast without being fussy.

Accessories & Setup

The CSV R ships with the Yamaha 4CM ebonite mouthpiece, a silver-plated cap/ligature, and a protective case - enough to get you on stage, but I recommend budgeting for a personal mouthpiece and reed preferences to truly tailor the response. I swapped the stock mouthpiece for a backup I already own and noticed immediate changes to brightness and articulation; that said, the factory mouthpiece is perfectly usable for auditions and rehearsals. The adjustable thumb rest made dialing in a comfortable hand position quick, and the strap ring is useful for long sessions or marching arrangements where shoulder support helps reduce fatigue.

Real-World Experience

I used the CSV R across mixed repertoire - orchestral excerpts, a few chamber pieces, and solo etudes - and it handled transitions between legato orchestral lines and more forward chamber writing with ease. Projection was reliable in rehearsal rooms and small halls; the tone carries without feeling harsh, and the center of the sound remains focused when I opened up for forte passages. Dynamics respond well - the leather pads and thicker key plating give the instrument a solid voice at higher volumes while preserving nuance in pianissimo passages.

The Trade-Offs

The main trade-offs are price and the included mouthpiece - as a custom-series professional horn the CSV R sits at a high price point where players will expect a top-tier mouthpiece and setup straight away. Some players may find they want to adjust key heights or replace the mouthpiece to better match personal technique, which adds to the initial cost. Also, like any grenadilla instrument, it benefits from consistent care and occasional tech adjustments - it isn't a "set and forget" instrument for the casual player who prefers zero maintenance.

Final Verdict

After spending concentrated time with the Yamaha YCL-CSV R I view it as a strong professional Bb clarinet - balanced, reliable, and built to a refined standard that will satisfy orchestral and advancing solo players. If you want a consistent instrument that projects with a focused core while remaining flexible for expressive playing, the CSV R is a compelling option; be prepared to personalize the mouthpiece and have a tech check the setup for your exact preferences. For me it replaced several compromises I used to accept on lesser horns - the CSV R simply lets me play with confidence across contexts.
