Herman Hauser Guitar care

Post by detwidkul » Wed Mar 13, 2019 2:40 am

Hi

wondering about the proper humidity for Hauser iii care, it is recommended to keep the guitar between RH 60-80 from the luthier. Anything lower for long period may have a chance to crack.

it is quite high, compare to most standard RH 45-60 suggestion.

what do you guys think? it is hard to maintain such high humidity when storing with other guitars
need to practice more!

detwidkul,
only one thing
comes to mind as a reason.
was this guitar built with it's
owners location, in mind?
i know that if a builder knows the
guitar will be living in an environment
outside let's say, the 40-60% average range,
they might build w the different environment
in mind.
for example, i know that some players are in
hot humid environments, and don't
want french polish as the finish on
their guitars.
** what was the recommended
humidity for the kathrin hauser guitar?
and did you order both from their shop?
BTW- congratulations on having
such a nice group of guitars listed!!!

***boveda makes 2 way humidity packs
w different humidity %. you can
probably order some in the range you
require.
if at first you don't succeed, try, try again.
then quit.
there's no use being a damn fool about it.

yes Kathrin recommend to keep her guitar with 60-80. so i search the reisbach Germany! and yes the humidity there around 60 -80 normally.

it is hard to keep them properly in my country.

Boveda probably is the solution for this case,
need to practice more!

I wouldn’t be too worried until it got below 30.

Have you got it right?
Europe is not tropics minus quite humid in some coastal areas.
You can not keep houses warm in wintertime in central
and northern europe without proper heating system
and that sinks the humidity.
60-80% sounds like bavarian outdoor humidity not indoor.

this is the quote from luthier

The dry humid can make a crack in the guitar, so if it is to dry for more as 2 weeks, the air wetness is under 60 % by for example 45 % till 30 % sure it getting a crack to 80 %.

By 50 % it can be that the fret come out on the side of the fingerboard, so the guitar speak to you..... please give me more air wetness, so if you do not look to that, the problem
starts to make a crack.

Yes 60 % is also o.k. from the air wetness, but more dry it is not to good for a long period. By 50 % the problems for a crack can start.
45 % are sure too dry. 60 % is a good way to keep the guitar.


--- so wetness is good for Hauser! OMG

2 things stand out. First, a translation error. Some of what Hauser says does not make sense. Second, the OP lives in Bangkok which is hot and humid--much more so than Germany. Was the guitar built for a non AC Bangkok environment?

Consensus about the humidity in workshop is somewhere 45 - 50 ish.
I doubt (but do not know) if Hausers have 70.

the humidity may be close to 80% but that is during the winter months when the temps are round about 3-5 degrees C. Warm that air up to 20 degrees C and the RH drops into the 30's. during the summer months it is close to 60%%

I can confirm that a Hauser III needs to be in an environment with RH of 60%. I left my Hauser III in a hermetically sealed case with constant RH of 50%, and after a month the ends of fret wires were sticking out. The RH at Reisbach must be pretty high all year round.

I would assume the Hauser folks can afford a dehumidifier so we can rule out poverty, but why would they build a guitar requiring an environment which is more humid than for most other guitars? Is a humid guitar the secret to the Hauser sound?

Maybe :)
It is also possible that they have a huge wood stash that is stored at 60% RH for generations and want to build their guitars in the same environment for stability. All I know is that I have to buy special Boveda Humidipaks to keep the guitar case at 60% RH.

I have a H3 that has been kept at around 45 to 55 for a couple of years.
No problems thus far and the guitar hasn't "speak" to me yet.

Personally, I'm very wary of humidifying inside the case ever since I heard Martin Simpson tell me of a guy who did this rather agressively, with the result that the top warped +++.

You will not overhumidify the case using the Humidipak system. You can if you use conventional humidifiers (Oasis, Dampit etc).

I've wondered the same about Hauser guitars. I agree it doesn't make obvious sense.

The most likely reason I can see is that previous Hauser generations had less control over their workshop climate than we have today, so it's an aspect of their tradition, like a secret sauce. Today they might choose to control the climate in their shop the same way it used to be done, or at least to keep the RH within a range that Hauser 1 would have worked in.

If that's not it, then maybe their hygrometers read on the high side. Something about the way they are/were calibrated, or the type of element inside them ....
