Over the last few years, I've been experimenting with progressively more open bass clarinet mouthpieces, as some of you who frequent this sub-forum may have seen in other threads. Since I'm cooped up at home practicing social distancing on a rainy Saturday, I thought it would be fun to share some of what I've been interested in, mouthpiece-wise, on the bass clarinet and see what other people's experiences have been. I know I have seen others here make reference to some pretty open bass clarinet mouthpieces.
I'll preface the following with the disclaimer that these are just my opinions and I am just a geek who likes to play the bass clarinet.
I'd also like to add that, though I'm not sick, I've been working from home and limiting social contact for a week now, so things might get a little weird.
Background
I have a classical background but generally haven't played "classical" music outside of the occasional casual clarinet quartet for the last 8 or 9 years. I mostly play experimental music, often improvised, and a little jazz. I don't play for a living, but I generally play about 5 or 6 hours a week.
When I play, I am always looking for a sound that has some edge, but in particular a strong "core", which I associate with a sound that has a strong presence in the mids that makes for a relatively smooth transition to the high partials. When I hear a lot of players, especially jazz and experimental players, there is often a strong fundamental and a lot of high partial edge, but the mids are not there to support the edge. I think this is similar to the soprano clarinet ideal of "ping" in the tone, though most classical players would shy away from the levels of edge that I like. At some point, I named this well-supported edge "klang." So I'm looking for that klang and this is what's working for me.
After 9 years, a music degree and countless performances and practice hours on a very "normal" Fobes San Francisco RR facing, I started experimenting with a Vandoren B50, followed about two years later by a Selmer Concept and a Fobes 10K with a 2.15mm tip opening.* All of those mouthpieces are very good and I could probably play just about any gig on any of them without anyone complaining. The Fobes in particular is very special and is what I would still probably use if I were playing in wind ensembles and orchestras all the time. A very sweet sound that can be pushed moderately hard that maintains a good focus level at all dynamics. It definitely had the klang at most dynamic levels, including louder ones than I had previously thought possible.
Pomarico Jazz**
My general life philosophy, though, is that you never how far is far enough until you've gone too far. Naturally then, having found what felt like the holy grail of mouthpieces, my instinct was to ask "well what if we went even further?" I was starting to play more with drummers and sax players and, though I could sound good at a louder dynamic than before, why not see if I could have more?
So about a year later I bought a Pomarico Jazz** from WWBW.
The Jazz** was another eye-opener for me. When I checked it out visually, it looked pretty gnarly. The throat was visibly off-center, the rails were a little uneven and the little bit of rollover baffle was a lot more rollover baffle than I had ever played on before. But when I actually put a reed on it and played it, there was definitely something there!
It had a huge sound that wasn't anywhere near as edgy as I thought it was going to be. The lower register had real bark, but that's easy. Most bass clarinet mouthpieces will do that. The upper register was what blew me away. When I first played the B50 coming from that Fobes RR, I had been drawn to it because of the feeling of "headroom" it gave in the clarion, especially the upper clarion. I could really lean on it and it would just come out so clear and strong and secure, without any feeling like it wanted to leap up a partial. In pursuing more open mouthpieces, I was really hoping for that feeling...but more. The Jazz** delivered that for sure. So strong up there. I really like to learn sections of sax transcriptions on the bass clarinet and that can get a little hairy trying to really play strong up there to hit those lines as naturally as on a sax, especially jumping across the clarion <-> altissimo break. The Pomarico really felt like I could push those notes the way I wanted to and not have them feel too out of whack with the chalumeau.
The places it came up a bit short were its general reed-pickiness and, unsurprisingly, its softer dynamics. There was definitely a lot more resistance in this mouthpiece than in the Fobes 10K I was playing. That made playing softer a fair bit of work, but I decided the tradeoff was worth it for about 6 months, but it did come to really bother me. I hate an overly-resistant setup and I really hoped that it wasn't just the resistance that gave me that headroom.
The first Selmer
At some point I was over at Mike Manning's workshop getting my bass clarinet adjusted and I mentioned my reservations about the Pomarico. After chatting for a bit, we decided that we shouldn't start modifying my main mouthpiece, but that we could probably turn another mouthpiece into something comparable. I decided to come back with a couple of mouthpieces as candidates for him to reface and we could pick which one seemed like the best fit. He mentioned that he'd had good success refacing the older-style Selmer mouthpieces, so I brought in a Selmer H that I had ordered at some point and never liked (the facing was visibly a mess). I also brought in the Concept, since I felt like it had potential, but just wasn't quite doing it for me.
First he measured the Pomarico, which had a fairly uneven facing. Not terrible, but not perfect. Then we decided that we'd try modifying that older Selmer, since he was familiar with those mouthpieces. He put a facing that was a perfected (symmetrical) version of the Pomarico facing on that one and opened it up to 2.58mm. That one had effectively the same facing as the Jazz**, but with a concave baffle starting right behind the tip. He was able to leave a little material right behind the tip that was there from opening it up, but not a lot. The floor of those older Selmer designs dips lower than the bore of the mouthpiece, so the transition to the bore is actually a step up. I put it on my horn and it was interesting. It has a big, broad sound, but I thought it sounded a bit too hollow. It was missing some of the high-mids that I like, which I think kept it from picking up much focus. I think it might be a little too open for a mouthpiece with so little baffle material.
So after that experiment, we decided he should take a pass at the Concept. I had been a little hesitant to go after that one, since I did kind of like it as it was. But hey, what the hell.
The Concept
That one came out incredible!
The concept has a pretty thick tip rail stock from the factory and a lot of material near the tip and in the floor area back from the tip to the chamber. It has an interesting trapezoidal throat that means the floor steps down into the bore. Interestingly, my Fobes 10K does the same thing, but it's a little less of a pronounced step. Because of that massive tip rail and the abundance of material around the tip, Mike was able to give me a short, but pretty high rollover baffle carved out of what was already there, without adding any material. So, in the interest of seeing how much is too much, he opened it up to a 2.58mm tip and left the baffle pretty high. Facing is 27mm, I believe. It was interesting, but a bit too brittle, so we went through a couple of rounds of lowering the baffle a bit. At some point we agreed that we should leave it a little higher than I am used to since we could always take it down a bit later.
We did one more pass at this one a couple of weeks later to take a little more out of the baffle and now it plays great. It has a lot more baffle than the Pomarico, almost as much as my Lamberson L7 tenor mouthpiece. Way more than I would have guessed would work for me.
The sound overall is fairly bright, but I find it to be very rich, with what I'd consider a strong, focused core sound that gives me the klang. It can be pushed outrageously hard. Much harder than any bass clarinet mouthpiece I've ever played, and not by a small amount. It gives the feeling of headroom in the upper register without excessive resistance (just enough to work with) and the lower registers speak much more easily at soft volumes.
I've been on this modified Concept for about 5 months now and am still loving it, with no further modifications. I sometimes think that I should see if the baffle can come down a bit, but I don't want to make changes that aren't reversible, especially when I don't know if they'd be better. At soft volumes, it takes a little bit more of a conscious voicing effort to get the throat tones to speak with sweetness and clarity compared to the 10K, but it is totally doable.
Photos
Having these three mouthpieces all with similar facings but totally different internal dimensions has been really interesting for me. They are all in the same ballpark, but play totally differently from one another. I've included some photos of the Pomarico and the two refaced Selmers.
Check out the different baffles:
Left to right: refaced Selmer H, refaced Selmer Concept, Pomarico Jazz** (hard to photograph)
and the different throat designs:
Hard to really see the step up from the floor to the bore in the Selmer H.
So what did I learn from all of this?
Overall, I'd say that there's still a lot to be developed where bass clarinet mouthpieces are concerned. I think to this point, we've been constrained by assuming that bass clarinet mouthpieces should have a similar amount of variety as soprano clarinet mouthpieces. I personally think that, much like the saxophone, the bass clarinet has a wider variety of "acceptable" tones than the clarinet and while we don't necessarily need the same variety of equipment as for the sax, I think more variety in production equipment would be worthwhile.
I think there are a lot of us who, despite having worked hard for years on our technique and our tone, find ourselves running into the limitations of our equipment in ways we've just accepted as how it has to be. There's no substitute for putting in the work, but I do think there's room for equipment to accommodate those of us who want something else.
It's exciting to me that the B50 even got made. Putting it out at that price point encouraged a lot of people like me to take a chance on something that seemed pretty extreme until I actually played it. Hopefully there is a B60 in the works!
* IMPORTANT NOTE: Last time I mentioned that 10K with the 2.15mm tip, a few SOTW-ers reached out to Clark to ask for one. Let's be clear that it was a one-off experiment. Clark never put that model into production and I happened to reach out to him to ask about more open mouthpieces right when he'd made it. I don't think Clark liked it very much and he has since released a (very) slightly less open 10K mouthpiece that I bet is very good. Clark is a great craftsman and a great player, so if he chose to make that one, it's probably because it's better. Please don't write to him to ask about the one I have. He isn't making more and you can't have mine. Buy the one he actually makes.

Hard to really see the step up from the floor to the bore in the Selmer H.
So what did I learn from all of this?
- This would all have been pointless if I didn't have a pretty clear sound goal in mind and a well-developed idea of what I need to do with my voicing and air to sound the way I want to sound.
- I always sound like me. The mouthpiece just makes it easier or harder.
- I think there's room for bass clarinet mouthpieces to get much more open than most of what's on the market. I'm not ready to go further than these right now, but I think there's room for a production mouthpiece more open than the B50. Doesn't mean everyone needs to play one, but it's a little funny to think about the variety of designs out there for the saxophone relative to the bass clarinet. The full spectrum of bass clarinet tip openings from Vandoren and Selmer right now is about 1.84mm to 2.15mm (.072" to .085"). That's a tiny range! There are some smaller manufacturers making more open mouthpieces, like Pomarico, but they don't have the market share that Selmer and, especially, Vandoren have. Look at the influence the B50 has had since it came out a few years ago!
- Bass clarinet mouthpieces can have a little baffle. Like with sax mouthpieces, I would guess that the more open you go, the more baffle you can get away with. I think the bit of rollover baffle gives an interesting color and makes the bigger tip opening a bit more free blowing. I'd actually be curious to know what a moderate step baffle would play like. I generally prefer a moderate step baffle over a higher, shorter rollover on the tenor sax (10MFan Robusto vs Lamberson L, for example). I find it's a bit smoother sounding and less gritty. I don't know if that would translate at all.
- I think I prefer a bore design on the smaller side. The Fobes 10K and the Concept both have smaller bores than the Pomarico and especially the B50. The Selmer H has a bore comparable to the Concept, but I think the lower floor takes away some focus.
- I probably wouldn't start a beginner on my mouthpiece or the Pomarico Jazz**, but I don't think it would be a problem for a beginner to start on a B50. I hope that eventually we start to look at the B50 as a more middle of the road mouthpiece once options become available for us.
Overall, I'd say that there's still a lot to be developed where bass clarinet mouthpieces are concerned. I think to this point, we've been constrained by assuming that bass clarinet mouthpieces should have a similar amount of variety as soprano clarinet mouthpieces. I personally think that, much like the saxophone, the bass clarinet has a wider variety of "acceptable" tones than the clarinet and while we don't necessarily need the same variety of equipment as for the sax, I think more variety in production equipment would be worthwhile.

It's exciting to me that the B50 even got made. Putting it out at that price point encouraged a lot of people like me to take a chance on something that seemed pretty extreme until I actually played it. Hopefully there is a B60 in the works!
