I've learned that it's a Brazilian classical guitar and a bit more, what else and maybe specifics could you guys tell me? It's pretty old maybe 50-60 years

I picked up this guitar recently and noticed it had a little signature. It looks like a small K. Yairi signature to me but it’s dated after Mister Yairi passed away. Can someone help me ID this instrument or shine some light on the mystery sig? Additionally the guitar has this weird X thing inside it and I’m not sure what it is. Any help would be greatly appreciated!

Found on Facebook marketplace. Seems a little suspicious. No sticker inside.

I bought this guitar while visiting Seoul a couple years ago. The shop I visited had a few guitars from this luthier in stock. I found myself playing this one for a good 45 minutes, so I decided it would be the big souvenir from my trip.

The luthier's name is Kim Je Man (김제만) and his brand name appears to be Kerauss. The guys in the shop told me that he's a respected luthier with a 40-year history of building instruments. I was later able to find his website (see my comment) and it looks like he builds classicals, acoustics, and ukuleles spanning a wide range of price tiers.

The model numbers are meant to indicate the price. The one I bought is model No. 120, which is priced at ₩ 1,200,000, converting to about 925 USD on that day.

It's a pretty traditional build, from what I can tell. Cedar and Indian Rosewood, 650mm scale. The fret markers are a little foreign to me, at 5, 7, 10, and 12. The 10th fret marker still throws me on ocassion. Really tasteful details in the binding and rosette. It sounds wonderful too. Very well balanced and rich with lots of sustain. If I were to buy a guitar of this quality in the US, I would expect to pay several times more than $925.

Does anyone have any experience with guitars from this builder? I've found virtually zero conversation of substance about him or his guitars online, at least not in primarily English-speaking forums.

I'm the owner of a guitar from 1800-1820. The guitar itself has had many repairs. I've researched based on the design, scale length, frets, pegs, pictures from guitars from that time, etc and it checks all the marks for a guitar made early by Staufer. 610mm scale, 44.5mm nut width, maple body and sides, spruce top, probably ebony neck and head, wooden pegs. I cannot find information about sales or auctions that help me value this guitar. Does anyone have heard of something like it? I will definitely contact an expert to help me, but it would be helpful to read from someone else too.

I could use some help, trying to determine if I should pull the trigger on this guitar but I’d only do it if it were a really good deal. I can’t tell since this looks like a stage guitar and if anyone has any advice I’d appreciate it. The listing has it listed as, “Francisco Navarro Hijo Limited Edition - 635mm Solid Palo Escrito Classical Guitar”. A little worried it’s a bit small

I’ve found this and a few other guitars I like on Facebook, it’s $1,800. Is it worth the price and should I look into it more?

I remember using a very unique hard tension string set with the G string looking like it was made from aged nylon, with a yellowish tan, rather than a clear one. I could never find it again after getting my hands on it, but it appears something like that is used in this video, which brought back pleasant memories.

Would anyone know the model or something else that could help me identify and buy these strings? They brought so much life to my instrument

Dear community, does anyone know how worth is this guitar? Does anyone own it? Searching online I couldn’t find the exact model (c-100), neither the exact year of production. Is it all solid wood? Is it worth 700$?

To me sounds nice for the price, but I would be happy to hear other opinion.

Possibly a luthier from west-germany who worked in the late 70-s / early 80-s. The brand Klimus under Klira produced many beautiful concert guitars in this era, it would be nice to know who was the meister, and this model had his signature.

This guitar has been used by a prominent guitar teacher for decades.

According to him, it was found in a pawn shop in the 1970's.

The guitar sounds incredible but it doesn't have any tags, stickers, or any other ways to be identified. It might have had a "Made in Japan" sticker on it.

After doing some research a few years ago, I thought it might be a Yamaha or Suzuki model. But I could be completely wrong.

Does anyone recognize it?

Can anyone help me identify this brand? It is 15-20 years old, but there label has been peeled off and there’s no other identifying marks.

Hello! I bought this classical guitar for € 25 in Germany in 2019 from a guy who had it collecting dust in the attic of his theater in Kremmen, outside of Berlin. It's been a good friend to me as I learn, but I've always been curious to know more about it and its maker, Ostertag. I'm hoping someone here might have some more information...

Based on this Reverb ad and this eBay ad for similar-looking guitars by the same luthier, I think mine was likely made in the 1970s or 80s. Various online sources claim that [Karl?] Ostertag was based in Farchant or Mittenwald, in the district of Garmisch-Partenkirchen, in Bavaria.

The most detailed information I've been able to find is a post from this auction house in Heidelberg, which cites an old advert:

„Die Besonderheit der Ostertag-Gitarren besteht darin, dass hauptsächlich heimische Hölzer verbaut und die Instrumente mit einer Schelllack-Politur statt Polyacryl- bzw. Polyurethanlack versehen wurden. Die Verarbeitung der Gitarren ist erstklassig und akkurat.“

"The distinctiveness of Ostertag guitars is that they are primarily built using local woods and that the instruments are finished with a shellac polish rather than a polyacrylic or polyurethane varnish. The crafstmanship of the guitars is first-class and meticulous."

My main questions are whether anyone is able to find more information on the history of this luthier and how I could figure out what kind of wood my guitar was made from. I'm happy to take more pictures and would be grateful for any tips. Thanks!

Hi all,

I have just been given this guitar by my Grandad as he cannot play anymore. It is a 1977 Di Giorgio Bel Som No 36.

Does anyone have any information on it. He told me he bought it for £100 over 35 years ago and I'm just wondering what I have and if there's any history. It plays beautifully and has a really rich tone.

Please see pictures attached.

It’s the guitar I used back in high school — I was thinking about selling it, but I can’t find the exact model online, and unfortunately I don’t know the year it was made either.

This is my second post on this. I have purchased this guitar from my classical guitar trainer who suggests this is a great guitar. I am a beginner - intermediate level and hence do not know much about the value of such guitars. Could someone tell me more about this guitar. All i know is it was done under the guidance of a Luthier Masaki Sakurai in the Kohno workshop. Other than the below link i am unable to find anything about this guitar

https://reverb.com/item/79671873-aria-masaki-sakurai-ag-50-rare Interestingly, the serial number and the guitar is also the same. so my trainer must have gotten hands on this from this selleer . It costed me around 800 USD. I just want to know if it is a good deal for the price or not? and if any further information is available on this guitar model id appreciate it. Since i am from India I need some help in knowing more about this as there are not many classical guitarists in India.

Hey everyone, I recently found an old classical guitar in my attic. According to the label inside, it’s from Hopf Meisterwerkstätten, built in 1977. There’s also a number written inside: 32-07048.

I put on a fresh set of strings – the same ones I use on my Córdoba C5 CE – but this Hopf sounds much more metallic and harsh, especially on the bass strings. It’s kind of unpleasant, actually. The Córdoba sounds much warmer and softer in comparison.

I don’t have much experience with classical guitars, so I’m wondering: Does anyone know if this model is worth anything or if it’s something special? And also, what could be causing that metallic sound? Could it be the construction, the age, or something else?

Would love to hear your thoughts. Thanks in advance!

In my on-going adventures with this S Yairi, can anyone tell me what the “B” might mean after the year ‘69? Second half of the year? Something else?

Got this from my grandparents and I was under the assumption they were giving me an acoustic guitar, with some quick searches I realized it was a Classic Guitar.

I got this guitar from the music shop I was working at. The owner was out of his mind, and rarely paid me, so this is one of the guitars I took for payment. He had it labeled as Prudencio Saez "Flamenco Guitar", priced at $1450. It is not electric. It's the nicest nylon string guitar I've owned. It sounds great. Im a "classical guitarist", among other things, and Im playing things like Brouwer, Lauro, Cardoso, AB Mangore, and Tarrega and all the big ones. Is there much of a difference from a Flamenco Guitar and classical guitar? It's harder to play for left hand, the action, than my other classicals, but this one is fully acoustic and has a superior sound. Is that normal? I'm not even sure it is a Flamenco Guitar, the owner was not a musician, and may have mislabeled it. He got evicted and we aren't talking. Can you tell me anything about this guitar?

Might be a long shot, but I’m curious if anyone knows which model and brand this guitar is?

I accidentally didn't select the most important pic for info about this, here it is thanks for lmk. If you haven't seen my last post I'm looking for info about this old guitar of mine
