screw bell case roundup

jacobgarchik · Post by **jacobgarchik** » Sun Feb 16, 2025 9:47 am

According to these (somewhat confusing) specs the protec is 6-8" deep, sort of shaped like a pyramid. Am I reading these right?

"Weight: 5.95 lbs; 2.7 kg
Exterior dimensions (tuning slide end): 35.5(l) x 8(w) x 12(h) "; 902 x 203 x 305mm
Exterior dimensions (bell end): 35.5(l) x 6(w) x 8(h) "; 902x 152 x 203mm
Accommodates bells up to 9" (229mm)"

https://www.protecstyle.com/SCREW-BELL- ... O-PAC-CASE

Compare to the Marcus Bonnas, about 5.5", or Holton, less than 5". They are both flat cases, not pyramidal.
I believe this is because the cases are structurally hard styrofoam covered in cordura, as opposed to fiberglass (bonna) or plywood (holton), so they need to be thicker to maintain stiffness.

The prototype I had was flat. But it may have changed a bit.

did it seem thicker than the competitors?

Burgerbob · Post by **Burgerbob** » Sun Feb 16, 2025 11:10 am

It was a bit thinner than my Chinese screwbell case (Y-Fort), but larger overall. I used it for a bit instead of the stock case, it definitely had some advantages in getting the horn set up more easily.

Since I live close to the trombone shop, I'll probably head in and take a look at it once they come in. Currently looking at getting a cut bell, and protec is a good option being roughly $250 cheaper than an MB

Since I just got one of the Marcus Bonna screw bell baby case, I thought I’d share a quick size comparison photo.
This is the Lawler hard case, the MB baby, and the Basilli side by side. I forgot to reattach the Basilli sheet music pocket, but you can still get a pretty good idea. Amazingly, the MB is the only one I can fit a Rath R3F in.

In what ways did the Rath not fit?

In the Lawler Case, it doesn't really fit at all. In the Basilli case, it fits fine without the valve section, but when I add the valve, the trigger mechanism plus thumb screw just makes it so I can't quite squeeze it in. (Mostly the trigger is too wide). It's a tight squeeze in the MB baby, but it does seem to fit. (I also love the storage for the trombone stand on the outside).

Seen this before…. Not sure I’ve ever seen a worse idea for a case.

At least parts to repair will be unique and difficult.

Not 99%... 100!
It IS shorter (read description for all 3 models), as I understand "cable" means "handslide" there... In original German description they use word "Zug".
Actually it is Yamaha 350C conception, just made by German craftsman.

Just ordered a "Plano" 36" gun case what I will set up the interior foam to fit my screw bell. I thought the price and protection were outstanding versus building from scratch, $110 plus tax free shipping. Will post photos with my horn inside when it arrives.

New member here. I purchased a B.A.C. custom screw on bell recently. I had a Marcus Bonna case for it for a little while but I felt it was lacking in the trombone stand department. I ended up purchasing a Pelican 1700 protector long case for it. It works great, though a little heavy. Once I have permissions to upload pictures I’ll add them to the thread. It works well and it fits everything I would want to take to a gig (including the trombone stand).

Last year when I went to Japan to bring my new bass home, it took me almost 1 hour at Yamaha Ginza, amidst sympathetic gazes from the shopkeepers, to set the fitting up

Not counting another 30 mins at the hotel. But I have to admit, it is the best (if not the only) screw bell bass case in the market.

Yamaha recommends the MB Baby with their cut bell horns. They look smaller and much thinner, but I don’t like the way the bell is secured with a leather strap.

Here's the preliminary result after tracing and cutting foam. I still have some tweaks to do but it is actually usable in it's current state. I'm planning on adding some cloth lining under the bell and accessory compartment to keep things from slipping under the foam. (Hot glue will set everything in place when I'm happy with it.) I was hoping it would be lighter but at 11 lbs. it seems to give excellent protection.

Someone will probably ask so I'll explain the balance weight. Standard Bach didn't do the job so I used a vinyl album weight which I never use for playing LPs since it slowed down my turntable. Hot glued into place and easily removable in the future.

baBposaune · Post by **baBposaune** » Fri May 02, 2025 5:11 pm

For anyone who might be thinking about making a detachable bell case from a 36" Plano gun case, know the following: if an inexpensive solution is what you seek, these are available from Amazon for around $90, so I could've saved $20 if I had checked. The DIY labor part is not terribly difficult. It weighs more than I was hoping for but I did not want to build one from scratch. The total $ for a scratch build could easily have cost double.

TromboneConcerto · Post by **TromboneConcerto** » Fri May 02, 2025 7:26 pm

I own both a DAC case (made from a viola case) and a MB with the detachable slide case.

The MB is far superior in every way. It is about the same weight, doesn't have that glossy plastic exterior that will scratch and scuff, and the detachable slide case has saved me a few times on flights. You also never have to worry about the slide being hit by the bell, because they are fully separated.

The MB is also slightly thinner. I bought a Pelican Storm Rifle Case and when I need to check my horn I put the MB Case, with the horn in it, fully inside the rifle case! It closes nice and tight and is an excellent solution for flying when it's a complete no go in the overheads (small plane, Japanese airlines, etc). The Pelican case even leaves a bit of room for clothes which acts like foam to keep the case from moving around in there.

This isn't saying the DAC case is bad- it is very light, gets a lot of comments and protects my horn very well- but I don't think it competes with the MB.

The pelican cases are definitely heavier but worth it. I feel like if a photographer can trust their cameras in a pelican I can trust my horn in it. It’s bee tossed around a bit and the horn is fine.

The case made by Lion Carbon Fiber in Hong Kong has arrived last week.
It is as light as the carbon fiber Marcus Bona Baby. I ordered mine in the metallic gray color, but there are plenty of color choices.
My Bach 42T fit nicely in the case, but a horn with a wide chassis like the Shires needs to be placed inside the case so that the lever and hand slide do not interfere. More movable pads and cushions would be nice.
Overall I am very pleased with the quality of this case.

I know ultimate brass had some prototype cases. Very, very few of them were made. I had one and ended up selling it, as I felt that the prototypes lacked enough padding.

mbarbier · Post by **mbarbier** » Fri Jan 09, 2026 8:56 pm

Not a new case, but case adjacent. I'd assume other folks share the same, minor, complaint with screw bell cases that you can no longer bring an in bell practice mute as easily when traveling. Recently got a Wallace compact practice mute and found that it fits by the bell flare in the mona tenor case- was excited and wanted to share. Don't like it as much as the normal Wallace practice mute, but it's a pretty decent mute. Glad to have a mute that fits in the case. It's a bit tight, but seems ok.

alberttrombone · Post by **alberttrombone** » Sun Mar 08, 2026 5:04 pm

Thanks! It definitely seems good option, good trombone security and with a lot of room to travel with the ipad an even bone stands, ipad stands or anything that fits in the big pocket. And the price is more almost a third of a MB...

mbarbier · Post by **mbarbier** » Sun Mar 08, 2026 6:28 pm

I recently saw them in person and was comparing next to my bone case. It's quite a bit bigger than the Bona in a way that would give me pause if being bought for travel. Outside of it being solidly bigger, the shape and the large Zipper pouch on the outside really take away the "it's a string instrument" assumption/excuse you can use with the Bona (or some other cases). But then again my bona was like $450 when I bought it so it's also a skewed opinion.

The Gard one, while a soft case, is VERY small and not much more than the Protec.

On the Protec side, at the same event one of my colleagues tried a different case for their Bach and it just didn't fit a Bach slide? It was very strange to given how prevelent the Bach 42 is, so just also gave me a bit of a suspect eye towards them that I didn't previously have, so that's also probably colouring my opinion. But the cut bell case of theirs did feel needlessly large.

NordicTrombone · Post by **NordicTrombone** » Mon Mar 09, 2026 2:22 am

Speaking of Gard, they've got two newer options that seem really small. Could be a great option if you don't mind a softer case

alberttrombone · Post by **alberttrombone** » Mon Mar 09, 2026 4:32 pm

Wow, that one is so thin! Maybe it works for people who just travel with their car to gigs, but for a city transportation/airports seems quite risky...

About the other Gard case, I bought the Gard 21C-ESK and I sold it after two weeks.
Didn't like at all the separate compartment for the slide, and it has a weird balance in the back.
I was bumping all the time at the subway doors and other places. It's quite soft and I don't trust a lot in soft cases for travelling through the city and going to gigs.

About the "violin" comparison for plane traveling, maybe in the US it works, but in Europe when traveling with "cheap" airlines like Vueling you will never be able to bring your horn to the plane if its bigger than a cabin bag (max. 56x40x25cm), so a slide will never fit that measurements unless somebody comes with a screwslide system jajajaja

I'm really liking the design, and how light it is. But it's a bit on the expensive side. Though if you are comparing them to the Accord cases, also from carbon fiber, then it's about the same I guess.
