Gewa Violin case question
Has anyone seen the Gewa Air Prestige cases? I'm in the market for a case and I'vee seen a lot of BAM cases but have seen no reviews at all about these relatively new Gewa cases. It seems like the Gewa might have better thermal protection than the BAM contour and slim line cases and at a slightly lower price.
They're basically the same as the regular Gewa Air cases but with leather on the outside for aesthetics.
You may want to read this thread:
Right -- you'll find almost everything you want to know there, and perhaps a lot more!
Thanks, also besides the leather on the top half of the case this case does have retaining ribbons and so does not open 180 degrees.
It seems they've listened to some of their critics.
Plastic and composite cases do not offer protection against accidents, or thermal protection, as well as plywood cases. I would not recommend getting one, unless you play a plastic violin...
Thermal protection figures are excellent this isn't fiberglass which I would never get. I really think the composites have improved quite a bit. The anecdotal evidence I have seen from a few previous generation Gewa air owners is very good vis a vis thermal protection. Also my shaped Mooradian padded cover will fit this case I'm sure.
Speaking as someone who actually owns a Gewa Air case and an often-recommended Bobelock plywood case:
Whilst I haven't had personal experience of Gewa's latest plastic cases, I have in the past had two plastic hightech cases from BAM. If the Gewa cases are made in a similar fashion to the BAM hightech cases, they are not fit for purpose and, IMHO, ugly.
Those composite materials work when its cold, but sunshine is a real problem!
Jeff, please let me know to which factual inaccuracies you are referring, and I will be happy to confirm or correct them.
"it's not possible for the rebound to have a greater acceleration and peak force than the initial impact."
Jeff, I asked if you would point out the “factual inaccuracies” that you claim that I expressed, but you haven’t:
I'm looking forward to seeing the data set from your study, I think it'll settle a lot of the issues and arguments that take place over case materials, etc.
Thank you, Michael. The "Violin Cases Safe in Movement" project ("Custodie Sicure in Movimento") is indeed ground-breaking research, because up to now there has been no independent study made on effective violin case protection levels.
Perfect - I like the sounds of this study. Not only are you smashing things, you are smashing things in a way that will better inform consumers and creators alike.
The whole problem really is the weight issue, which many violinists have truly taken to extremes. I've posted elsewhere an experience of mine, in which at a tradeshow a girl picks up a case only to set it down with a grimace: "too heavy" (the case weighed 2.3 kg/ 5.1 lbs). I explained that a modicum of material was necessary to protect the instrument, and she said "well I have other priorities".
I'll get in touch over those graphs in the near future, I really am curious. My motive for asking was to have published results - I don't doubt your own testing. From your posts and reputation I trust you to be 'up front' about things and not to dramatize or fib to make your own product something it isn't.
Hahaha! Thanks - I'll do my best! :-)
I have never understood why some violinists obsess about the lightness of their case, then fill the case with kilos of music, a music stand, and even their lunch...
I was waiting for Carlo to "weigh in"... ;-)
Do all plastics split easily if not reinforced with fibres?
I wonder about the thermal testing. I suppose that it's straightforward to put a few temperature loggers in a case. However, properly defining the environment is much harder to do reproducibly and meaningfully. Heat transfer from the environment to the outer surface of the case can be from thermal radiation, direct sunlight, and natural or forced convection. I'd argue that those processess dominate over heat conduction in the shell material. Natural convection and radiation have a thermal resistance of around 0.1 m2K/W combined, equivalent to centimeters of carbon fiber composite (2 m.K/W) or a cm of wood.
From my perspective as a manufacturer, I prefer real world testing over number crunching, and then use the indexes and math to try to understand what I have observed, learn from it, and maybe be able to make a better product.
@Michael McGrath. I already do have an Italian leather case but, as it doesn't match every outfit, I thought I would get one in every colour.
Black, dark brown, dark blue leather; beige or medium brown suede (not recommended for the cover).
I was thinking jewel colours... they are very in now.
Dimitri, my point is that the theory tells you which experimental parameters are important to control, not that you should calculate the performance without measurements. Of course, side-by-side experiments are useful for measuring differences, but you can't easily compare new data to old data. For example, foam in a sandwich construction may become less insulating in a few years, but it's difficult to notice without controlled conditions.
The number of variables is one of the biggest problems of measuring case safety.
I'm enjoying reading this discussion. :-)
Jeff, very interesting information you provide here. You take a theoretical approach to explain practical application; I find it better to take the practical approach and then analyze through theory. Fine enough.
Jeff, I see a recurrent pattern of Dimitry using a generic term ("shock", "stiffer") and you interpreting that as if it were a well defined technical quantity ("peak acceleration", "inverse elasticity modulus") followed by you attacking by stating that that quantity is not bigger/smaller, regardless of whether that quantity by itself translates directly into better/worse performance of a product. I don't think that that leads to a constructive discussion.
Lydia's post well addresses the importance of lightness in relation to what use the musician puts his/her case through. For those interested, I can explain that individual markets have different requirements, which often translate into slightly different versions of the same model cases sold there. For example:
I like backpack straps. I can't imagine a case without them.
As I happen to have a Gewa Air oblong violin case in my atelier, I also would like to point out that the bridge clearance measurements which a poster above quoted do not apply to this case.
Its pretty obvious who speaks from real world experience, and who is just throwing around figures he's read!!
Real world, Lyndon, that's where we live..! ;-)
@Lydia. Congratulations on the new Enigma. Which variation did you go for?
I got a custom interior, using the Concept 7 fabric from the Luxury options, black velvet, and silver-gray bow-ribbons, removing the wood trim for a more contemporary aesthetic. Here's a picture:
Wow! That is one beautiful case (fiddle does not look too shabby either). Super choice of lining and kudos to Dimitri and his team for flawless execution. Every time you open it must give you great pleasure, both aestheticly and in the knowledge your violin is superbly protected.
Flattery will get you everywhere, Carlo... I think you know that... :-)
I really love the case. I really love the fiddle, too. :-)
I think this is what I will get someday soon too! Great great case!
Lydia... you've got champagne taste ;-) ... and I am on a beer budget :-( ... but dream is good for you they say! I'm jealous!
Dimitri, just for humor: I'm trying to ruin everyone's day by bringing in more of the nuances of plate-bending mechanics.
Jeff, don’t worry about ruining my day, just keep in mind that I’ll be away next week so we either wrap it up now or take a short break before starting again!
Ah, I forgot your mention of the Musilia case. First off you should know that Musilia is not the name of the guy who owns the company, or a sub-brand of Musafia (it appears to be a contraction of MUSafIa ItaLIA, the name of MY company), but a name which was made up for… well, for whatever reasons, OK? I gotta love 'em... ;-)
Disclaimer: Musilia cases should not be confused with Musaica cases, which are even cheaper Chinese imports sold by A. Cavallo Violins in Nebraska with "Quality and styling equal to many costly European cases".
I'd never heard of Musaica before, but at $195, that case isn't cheap, so it'd be interesting to know how it differs from other cases in that price range, like a Bobelock. (It looks like a Musilia is almost $1k -- definitely not cheap!)
What sets Bobelock apart is that it's a company that has been a heritage going back over 100 years, and it's named after Steve Bobelock. The Musaica is a generic Chinese-made product sold under different brands, produced by a no-name company. I think where you see enough pride to put one's name on a product (see also Negri, Riboni, etc.) you likely get better quality.
Dimitri, I look forward to hearing about the results of your experiment with the plywood/foam/plywood panel, if you'd be open to sharing them. If you haven't gotten tired of reading my ramblings, I do have some suggestions and things to watch out for:
Thanks for the tips, Jeff. I'll see what my supplier of laminate thinks of all this and maybe do some testing later this year.
