Yamaha Slide Compatibility

Matt_K · by **Matt_K** » 2022-08-17 7:45 p.m.

Per popular demand:

The "medium" bore slides all seem to be compatible. I've found bells/slides from these "medium" bore slides to be compatible, and essentially the same length:

356(G)

445

446

630

645

646

Interestingly, the YSL548 bell section accepts the aforementioned small slides, and the lock ring is the same, but the tenon is a little too short so unless you get it EXACTLY right, it's wonky. But if you do get a tight fit, it actually works. I had a 356 slide on my 548 bell for awhile and it worked really well.

My understanding that I'd hope someone can corroborate is that all large bore tenons are the same as my 548 but I don't know that for sure.

Additionally, some basses... maybe the 622? has a Bach receiver. Jeff Cortazzo borrowed my bell section when his Mt. Vernon bell was in the shop about 10 year ago from a... airline incident. And he just put his Shires slide on it and it fit on about the same way a Shires slide fits in a Bach slide. Not great but not bad either.

My 643 and 548 are slides are interchangeable with the opposite bell sections. Interesting fact, the outer slides and the tuning slides are also interchangeable.

Matt_K · by **Matt_K** » 2022-08-18 8:53 p.m.

Yamaha seems to have bascially made like, one tuning slide for like... all of their medium/large models up to like, the 300 series. Maybe they have a different taper internally? Not sure, but the tuning slides on all of the models I mentioned are totally swappable. Also, you can get the tuning slide fairly inexpensively from them.

PaulT · by **PaulT** » 2022-08-22 7:11 p.m.

You can add the 640 to the list of compatible .525 Yamaha slides.

And the tuning slide is compatible between all 600 series Yamahas, .525 and .547. I have used the tuning slide from my .630 (with its cross brace and weight) on both my 620 and 640, respectively. (experimenting).

MrHCinDE · by **MrHCinDE** » 2022-08-22 7:36 p.m.

My 612Rii slide is a good fit on my Bach 42 bell. It’s a bit shorter than a Bach slide but perfectly usable after getting used to it for a few minutes.

Similarly my Bach 42 and Edwards large-bore slides fit well on the 612rii. The Bach slide with the 612Rii bell is just about short enough to be playable at A=442Hz for me, the Edwards slide is in a more comfortable tuning range.

I think I remember someone on here saying not all 612 slides are alike so YMMV.

I think we can add the oddball 350c and non-US 455, 456 to this list. But the 350c is not the same length as the others.

Klimchak · by **Klimchak** » 2022-08-24 9:51 a.m.

Also, the 353OR to the medium bore list. Just like the 455G except with a rose brass bell instead of gold brass. There is also a 353, no letter suffix, that is a straight .500”, similar to the 354.

DougHulme · by **DougHulme** » 2022-08-24 10:34 a.m.

The YBL 321 bass slide I have has fitted all the bass models I have ever tried it on, which is quite a few so I dont think they have changed the bell to slide fittings since they started productiion?

hyperbolica · by **hyperbolica** » 2022-08-24 10:50 a.m.

As noted in my 455 thread, 455 and 78/79/32/50h slides are compatible. The 78/9 combinations sound usable going both ways, but the 32h slide doesn't seem be playable with the 78/9 (although it does technically fit).

The 455 slide on the 79h adds a little punch to the articulation. The 79h slide on the 455 adds a little depth to the sound.

Matt_K · by **Matt_K** » 2022-11-17 9:08 p.m.

Anyone know if Conn 18H (Corprion) will fit the receiver on a Yamaha 354/M1?

soseggnchips · by **soseggnchips** » 2023-01-18 3:48 a.m.

Anyone know if the 352/354 bells are compatible with the .525 slides? Specifically the 455G.

Matt_K · by **Matt_K** » 2023-01-18 9:05 a.m.

No, the 352/354 is much smaller on both the tenon itself and the threads. The medium bore ones are actually very similar to the largebore tenons such that you can actually get the medium bore to fit in a large bore and the threads will engage... but it'll be a little loose.

However, the part to adapt the receiver is very inexpensive.

The basses have many different tenons. The 830 has a bach/edwards compatible slide, to a degree, wheras my 613 is totally different.

I bow to your supreior knowledge Aiden. Its why I put a ? after my statement. Although like I say I have put my 321 slide on about 4 different models and they fitted but I cant say which ones they were now so I am probably not much use in clarifying my own statement... Doug

I’ve got a medium bore Yamaha slide at the moment I’m trying to figure out what to do with if you want to send me a pm/email I might be able to work something out depending on what you’re trying to achieve

soseggnchips · by **soseggnchips** » 2023-01-29 4:51 a.m.

No real plans at the moment - I found a 354 advertised with a trashed slide and thought that bell on my 455 slide might be an interesting combo.

While I'm on the subject, I've found the 455G to be a very likeable horn. It's too front heavy (as all larger straight horns seem to be) and I find it a bit stuffy in the low register, but I think that's more of a mouthpiece issue.

OK, I see, then the dual bore doesn't work, of course, you must have the larger adapter.

Yeah, my 455g really grew on me quickly despite the front heaviness. I don't have low range issues with it. Interestingly, it seems to like smaller mouthpieces. I'm half tempted to get a 456 to see if that's better balanced. That could really be a horn that can do anything. I've talked some smack about Yamaha in the past, but this horn makes me want to take some of it back...

Dual bores have the same size tenon (outer diameter, anyway) than the other slides. The threads will not fit Edwards, and therefore won't fit Bach. I remember a Shires slide fitting a few years ago.

I'm sure someone will correct me if I'm wrong, but I've heard that the current 4xx series are just a rebadge of the mid-90s 6xx professional horns.

I've been using mine on 3rd in one specific big band as an experiment, and it's definitely been interesting. The low register stuffiness did turn out to be a mouthpiece issue. I switched from a Bach 4C to a DE XT/C+ setup and it's vastly better down low, on this and every other instrument.

I still don't know if I'll keep the 445 long term, but that's really just because I want an F-attachment for this part. If a nice 446 or 646 were to come along it'd be hard to say no.

455 or 445?

soseggnchips · by **soseggnchips** » 2023-03-24 3:33 p.m.

Mine's a 445G, the fairly common .525 intermediate model - sorry, I've just noticed I've typo'd throughout my original post.

I've never even heard of the 455. It looks like it's a JDM straight tenor version of the 356 (which we *do* get in Europe). Confusingly, it turns out there's also a 456A, which is Australian market-only, and seems to be a 445 slide (single-bore .525) on a 3/456 bell (8" instead of 8.5").

Actually, this is something I find mildly infuriating about Yamaha: they make a million different models and it seems to be completely arbitrary which are available in a given market. I wish they'd at least publish a single list of everything they make. That and serial numbers.

I wrote to Yamaha about dating my YSL-684G. Here’s their response.

Good morning,

I have a Yamaha YSL-684G trombone, and the serial number is 201305. Could you tell me the year it was made?

Thank you in advance.

Jerry Walker

Hi Jerry,

Thank you for reaching out to Yamaha. Unfortunately, that serial number is not coming up in our system. There are two likely reasons:

1. The instrument is older than our current database which starts in 1990. This particular model began distribution in 1987, so it is likely that it was pre-1989. However, because we do not have the data on these instruments, we cannot be any more specific than that.

2. The instrument is from outside the US market. The support email that you found is only for the USA market and unfortunately, we don't have serial number data for other countries.

Thank you again for reaching out and I'm sorry that we couldn't be of more help.

Best regards,

MrA · by **MrA** » 2023-07-06 6:52 a.m.

Hello all, not sure if this warrants a new thread or not.

I have a 682b (The bousfield valved open wrap one). I'm wondering if the yamaha medium bore slides may fit it's reciever. Specifically from say a 640/620.

And if anyone has actually done similar with the Yamaha instruments, and what results they got.

I've fouund myself playing first for eveything, and I've been considering a change to .525 or maybe even .508 instrument to help my high register consistency. A medium slide on the existing bell might be a good compromise.

Matt_K · by **Matt_K** » 2023-07-06 9:27 a.m.

Technically you should be able to fit and it will “work” but it’s obviously a little too small to be something I’d want to use full time. You may want to consider picking up a large bore slide and adding a 525 upper. I may have something sitting around from a similar project I was thinking of doing if you want to contact me

Chiptingle · by **Chiptingle** » 2023-07-07 11:33 p.m.

Has anyone here tried your medium bore slides with either a Conn 78 or 79H? I have a spare 79H bell, and maybe this is a less expensive way to get the horn out playing again.

They are interchangeable. Or at least, the 891 and 897 slides are interchangeable. I think they all have the same receiver.

For the 891 and 897, Yamaha also makes a .500 bore slide that will fit either.

Of all the combinations, the vanilla 891z is the best in my opinion.

No, or at least the 630, 645, 646, 356, and 446 all have the same receiver which is the similar tenon but the same locking nut as the large bores. Or at least it is as far as I can tell. I’ve had one of everyone of those slides and they all fit on a 548 bell section, albeit loosely.

Yes, that's my experience as well, the slide will thread on my Xeno but the tenon isn't quite there.

If someone watching this thread that owns a small bore Yamaha would measure the diameter of the tenon where the threads start and where the tenon ends it'll probably answer my question :pant:

Matt_K · by **Matt_K** » 2024-07-12 9:27 p.m.

For what it's worth, if you wanted th eparts, Yamaha stuff is pretty cheap and easy to get usually. You can probalby get a 446 slide receiver and have it put on your small bore bell section, and have a meidum bore tenon put on the small slide too. That's what I'm doing with my King equipment. Everything is going to have the 3B+ receiver except maybe my most recent project b/c the rotor I have is .493. But if I can make it work I will

Hello, from a high school student in Japan.

I have a YSL-456G and a YSL-3530R (i.e. a modern 455G), both medium bore and interchangeable.

These are both dual bore trombones, but I am wondering if a medium bore slide that is not so can also be used with the 456G.

The reverse is the same and I would like to know which models are compatible with the 456G slide.

My English may be strange because I am not good at English and I used a translator.

No, the "large bore" Yamaha receiver is different than the medium bore receiver. Well, technically the medium bore slide will fit in the large bore and the threads will secure, but the connection will be super loose. Easiest course of action would be to replace both the slide receiver (bell side) and slide tenon (slide side) on one of the sets to match the other. Yamaha parts are typically pretty inexpensive and readily available, a good tech would make short work of such a project.

I'm not aware of any stock 525/547 Yamaha slides fwiw, but another option if that's what you desire would be to replace the upper slide with a 525 on the 547 slide and that would at least accomplish getting the 525/547 working on a large bore bell section and I suspect would be cheaper than the suggestion I made above.

There are actually a few Japanese speakers here, so if something isn't translating right, you may consider posting the Japanese text in parallel with your translated text and someone might be able to help.

To the best of my knowledge, all of the Yamaha medium bore slides will mate with all of the medium bore bell sections. When I say "medium" bore, I mean all Yamaha 500/525 and 525 slides that I have tried (including 356, 446, 630, 645, and 646) have mated and, as important, had an acceptably similar length in both the slide in bell section.

Can confirm, owning both a 456G and 446, they do indeed interchange.

Tatsu · by **Tatsu** » 2024-11-16 6:36 a.m.

Thanks for the answers everyone!

I then also purchased a 455G and was able to pursue the setting by replacing the slide and main tuning tube. The replacement of the slide and, of course, the main tuning tube was more effective than expected.â

Anyone knows if the Yamaha 448 slides are interchangeable with the Yamaha 648 slides? I bought a Yamaha 648 and a cheaper hardware refresh could be to use the 448 slide section on it, but I am not sure if it really fits perfectly and if yes, how does it play? Anyone out there who may have already tried it?

biggiesmalls · by **biggiesmalls** » 2025-01-13 10:09 a.m.

Just throwing in a wild card: Elkhart 8H/88H slides will hook up nicely to Yamaha 641/643 bell sections. While the 641/643 slides have nickel silver outers reminiscent of large bore Holtons of the era, the red brass outers and Remington leadpipe of the Conn slide will bring the Yamaha bells very close to an 8H/88H sound and blow. Also, the 641/643 nickel silver slide can be mated with an 8H/88H bell for a bit brighter sound with some very crisp articulations.

641's can be had quite cheaply, so if you already own an Elkhart 8H or 88H, this is a fun way to add some cheap thrills to your quiver.

Pozanos · by **Pozanos** » 2025-01-13 12:45 p.m.

Thanks, I have a Blessing B88 which is based on the Conn 88H, and the outer slide surprisingly fits to the Yamaha 648 inner section. It has a more heavy feeling. However the entire slide does not fit to the Yamaha bell as the tenon of the Blessing is bigger.

But the Blessing I am planning to sell so I need another slide for the 648.

Is there a comprehensive model/spec list for Yamaha? I used to know where two different online spreadsheets were, and they are both defunct.

If you had a 354 and a 356 could you use the tenon from the 356 slide or the receiver from the 354 to build a single .500 single bore F att horn?

Maybe, tried, playable but still a little loose after fully tightening the nut

You... might be able to get the 356 tenon on a 354. I don't think a 354 receiver would fit on the valve of the 356 though. I don't know how successful you would be with that but it might work. I've seen crazier. The 356 I had were a .530" so it's not that far outside typical divergences. However, the lengths of the slide and bell are different on both models so intonation might be wonky too, even bore differences being accounted for.

Today I happened to try a 354 slide on an 891Z bell section, and vice versa. It works. I played both combinations a little and everything seemed fine. I didn’t check intonation though.

Would a Ybl 612ii slide fit my early model Ybl 612?

[quote="biggiesmalls"]Just throwing in a wild card: Elkhart 8H/88H slides will hook up nicely to Yamaha 641/643 bell sections. While the 641/643 slides have nickel silver outers reminiscent of large bore Holtons of the era, the red brass outers and Remington leadpipe of the Conn slide will bring the Yamaha bells very close to an 8H/88H sound and blow. Also, the 641/643 nickel silver slide can be mated with an 8H/88H bell for a bit brighter sound with some very crisp articulations.

641's can be had quite cheaply, so if you already own an Elkhart 8H or 88H, this is a fun way to add some cheap thrills to your quiver.[/quote]

Anyone try a 648 slide on a 643 bell section or vice versa?

Hi all - anyone know if the 80s 648 and 646 bells use the same receiver? I have a 648 that plays like a dream, and might just sell other horns if I could put a 646 slide on it. I really got inspired by David Marriott, Jr., who plays/ed a 646. And of course, nobody will ever imitate Robin Eubanks!

No, the .525” and .547” Yamaha slides are not compatible.

But, the Yamaha .525” horns are essentially the same bell section in regards to bell taper and tuning slide size, so putting a 646 slide on a 648 would be very similar to a normal 646 except for any variation in bell materials.
