How to… carve a bridge

It’s been a while since I posted anything in my little DIY series, How to…, like me previous post about How to… reset a Levin neck or remove a bridge. I did carve a little floating bridge for my Levin 65 over a year ago but now it was finally time to carve a proper ebony bridge for my K. Yairi YW-1000.

K. Yairi YW-1000 Made in Japan 1973I thought about getting a pre-made Allparts ebony bridge at first but felt that it would be more fun to make one myself from scratch instead. I ordered some rosewood and ebony blanks from Madinter, it thought it could be good to have some extra at home, and got started. First I removed the old bridge, it had two screws that was a bit tricky to get out but eventually I figured it out. I removed the bridge with a spatula that I heated on a normal clothes iron, it works like a charm every time. Start in a corner and work yourself towards the middle and be careful when it starts to loosen up so you don’t break it off and chip the top, it should come off slowly and without force. I planed the ebony blank and then used a cabinet scraper to get it even. I copied the old bridge and drilled the holes straight away. It felt easier to do this before the bridge was shaped, it would also have saved me a lot of time in case I messed up the holes and had to start all over again. Luckily everything went fine.

K. Yairi YW-1000 Made in Japan 1973Once the bridge was sawed in to a good size, I made it a couple of millimetres bigger on all sides, I drew the outlines of the final shape. I mounted the bridge blank on a piece of scrap wood with two screws so I could more easily work all around with the bridge firmly secured. I used a chisel to carve out the shape on the sides and from the top down towards the wings. I got a good round shape with a half round rasp and then it was just a hell of a lot of sanding to remove all the lines from the rasp and to get it smooth and nice.

K. Yairi YW-1000 Made in Japan 1973I glued the bridge on and after 3 days I strung up both E-strings and used a drill as a saddle so I could move it around until I got the intonation right, I forgot to take a picture of that. I marked out the saddle and then sawed a 3 mm slot. Next step was to create a bone saddle to match and string it up. Easy peasy, well it was a hard days work but it was easier that I thought.

Since it’s my 35th birthday today I’m going to post this guitar even though it’s not 100% ready yet, it was my birthday present to myself. As I mentioned earlier I recently became the proud owner of a 1973 K. Yairi YW-1000. It’s something I’ve dreamed of for many years and after a bit of hassle it finally arrived. The previous owner didn’t really give much of a description so I wasn’t really sure what to expect. Luckily it sounds at least as good as I had hoped for, if not better and it’s structurally fine. Having said that, there were a couple of things that I wasn’t overly excited about, like the bridge and the scratches on the top. I don’t mind worn guitar but there is one big scratch that is still a real eyesore for me, I’m sure I will get used to it and not even see it in a few weeks. The bridge is a chapter for itself, I really don’t know what has been going on there. It has been removed at some point and re-glued, it also has two screws that I doubt were supposed to be there and on top of that someone has added a bit of rosewood to make it higher and topped it of with a fret as the saddle instead of a normal slot and bone saddle. As soon as the wood shops open again here in Barcelona, a lot of shops are closed in August, I will get a piece of ebony and create a new bridge from scratch. Since I couldn’t wait a whole month to play the guitar I lowered the bridge and cut a saddle slot and installed a bone saddle for now, which has worked fine. It’s a beautiful guitar, it’s smells wonder full and sounds even better. This is my third K. Yairi and I have to say that it’s without any doubt the best Japanese acoustics I’ve played so far. I really love my K. Yairi YW-130 and K. Yairi TG-40 but nothing sounds as good as this K. Yairi YW-1000.

Yairi YW-1000 Made in Japan 1973It’s worn and has few scratches but nothing too serious, except for the bridge as mentioned before. I changed the machine heads to Wilkinson WJ28NGD open gear in gold, the original ones were in gold too but most of it had worn off and on top of that they were really heavy. I love all the abalone binding and the hexagon inlays in the ebony fretboard. I’m so gay for bling on guitars, the more the better, perhaps I’m the Liberace of guitars.

K. Yairi YW-1000 Made in Japan 1973As soon as I got the guitar I removed the fret, lowered the bridge by sanding it down and then I cut a proper saddle slot. Apparently the top of the bridge is rosewood on an ebony base so I had to paint the top black to match the rest. The bridge works fine but I’m not happy with how it looks so I will try my best to carve a new one in ebony and replace it.

The fist video is with the old makeshift rosewood bridge that the guitar came with, the second video is with the new ebony bridge that I carved myself from scratch, you can read about it here.

I did it, finally I found myself a K. Yairi YW-1000. This has been a goal of mine for years, or at least since October 2013. You never see them for sale in Europe and to buy one from the US or Japan would set you back at least $1500-2000 plus import taxes and the risk that it gets confiscated in customs, some countries are really picky about Brazilian rosewood crossing their boarders. This K. Yairi YW-1000 was made in the 48th year of Emperor Shōwa, meaning 1973, I love the Emperor based serial numbers. I will write a lot more about this guitar when I got it all set up, I need to re-glue the bridge first.

K. Yairi YW-130

K. Yairi YW-130 Made in Japan 1977K. Yairi YW-130 a Martin D-28 copy made in Kani, Japan in 1977

I recently came over a 1977 K. Yairi YW-130, a beautiful Martin D-28 copy. I’ve been looking for a D-28 copy for a while, just out of curiosity to see the difference between the D-35 and D-42 copies that I have. The Morris W-40 and Morris W-50 both have a 3-part back which gives them a lot of bass and punch in the middle so perhaps a Japanese made D-28 copy would be more bell like and balanced, like a real Martin, and I was right. The K. Yairi YW-130 sounds amazing, really clean and even all over, with awesome overtones that sneaks up on you if you let it ring out. It has a solid spruce top, rosewood back and sides with a simple ebony bridge and fretboard. I do love my Morris guitars and I think it’s a great brand, but nothing comes close to K. Yairi. The old K.Yairi TG-40 that I got a year a go is awesome too, but I think I prefer the sound of the new one. Perhaps my acoustic guitar preferences has slightly shifted from the Gibson sound to Martin.

Yairi YW-130 Made in Japan 1977I didn’t have to do anything to the guitar when I got it, I just changed the machine heads to Wilkinson WJ28NGD open gear in gold which I love. It’s a bit worn and have a few dents in the spruce top that I’m planning to figure out how to soften a bit.

K. Yairi YW-130 Made in Japan 1977I’ve really come to love guitars with the typical Martin volute, just like my Morris W-50, and the double dots on the 7th fret, it’s just beautiful. There is nothing better than a black Ebony fretboard on an acoustic guitar. I thought ebony was like rosewood until I got my Goya T-18 two years ago and it just blow my mind, there is no nicer fretboard material.

My new K.Yairi TG-40 has finally arrived, after 40 days stuck in Spanish customs. I have mentioned earlier that it’s a lot easier to import things from Japan to Spain compared to buying things from the US, well that was a lie. I have bought three electric guitars, mainly Greco’s from an eBay seller called Tokyowax. They all arrived within 48 hours so I stupidly assumed that everything from Japan would arrive quickly and without any problems, but no. Tokyowax uses DHL Express and they tend to deliver things within 2-5 days and you pay the taxes straight to them when they deliver the guitar. It wasn’t that easy with EMS Japan, that package went straight to customs in Madrid and spent 40 days in their lazy company. How can anything take that long? K. Yairi could probably have built me a new guitar in that time, if he was still alive. It seems like the only option now when buying guitars on eBay is to use the Global Shipping Program, that worked for my Goya 163 at least. Anyway, the guitar is amazing so it was well worth waiting for.

K. Yairi TG-40 Made in Japan 1977

It has a really nice tone with great bass response. It easily has the best bass of all my acoustics, even better than my Morris W-40 which has that Martin D-45 bass sound, this is nicer and a lot clearer. I guess it sounds like an old Guild D-40, at least if I can trust the Youtube clips I have seen since I haven’t had the chance to play one myself. It actually reminds me a bit of a Gibson Jumbo, like I mentioned in my Gibson J-45/J-50 post: “The Yairi TG-40 is a Guild D-40 copy, which was introduced in the Sixties as a competitor to Gibson’s J-45. The Guild D-40 became famous as the Bluegrass guitar for their even response over all the strings and I really like the sound of them, it’s actually not too far off from a Sixties Gibson J-45. With a bit of luck it’s going to be an awesome Yairi copy of an Guild which might sound a bit like a Gibson.”

K. Yairi TG-40 Made in Japan 1977I didn’t have to do much to it, it was ready to play when I got it. However, the pickguard was loose so I had to remove that, clean it up and then glue it back again with my trusty fish glue. When the strings was off I quickly polished the frets and oiled the ebony fretboard. I also installed a jack for my LR Baggs M1 and a strap button.

I bought this K.Yairi TG-40 from a really nice eBay seller called montebell86 who was a pleasure to deal with. The guitar was listed as “Taniguchi Gakki” Japanese guitar shop original model, very rare. Solid spruce top, sides and back in solid mahogany, neck in Honduras mahogany, bridge and Fretboard in black ebony. The label states it was made in 1977 but the serial number starts with 51 which was the 51st year of Emperor Shōwa and puts it to 1976.

K. Yairi TG-40 Made in Japan 1977K. Yairi TG-40 Made in Japan 1977I got this K.Yairi TG-40 fairly cheap since the pickguard needed to be reglued and one machine head wasn’t working properly. It also has two cracks, one on each side that has been professionally repaired and can’t be seen from the outside. Since the machine heads needed to be replaced I decided to change them for Wilkinson WJ-309 in gold, just like I did on my Levin 174


Here is a quick little comparison between the K.Yairi TG-40 and my Morris W-40, they sound pretty similar and I don’t think I would be able to tell them apart in a blind test. Well the Morris has a bit more bass and is a slightly weaker on the treble side, I feel that the Yairi is more even over all the strings.

Yairi TG-40 Japan Catalogue 1970'sK.Yairi TG-40in the Japanese catalogue from the late 1970′s. List price ¥60.000, around 420€, which must have been a fortune back in 1977. Then again, this was a fairly cheap guitar for being K Yairi, the top model cost ¥200.000, about 1400€.

Gibson J-45 / J-50

1955 Gibson J-45My new dream guitar, an old Gibson J-45

A year ago when I started to buy acoustic guitars I had no idea what the difference between a Gibson or Martin was or how different body shapes, models and tone woods affected the sound. I could easily have told you who was playing a Telecaster, Stratocaster or Les Paul while listening to a song but I could never have told you if someone was playing an acoustic Gibson, Guild or Martin. Over the year I have added 6 Levin guitars to my collection and 5 Japanese acoustics, two of them sold by now, and played a lot of new made Chinese and Korean guitars and I have come to following conclusion. My favourite acoustic guitar is an old Gibson J-45. This is nothing new, I realised that last summer after seeing Kris Kristofferson, I did a post about it with some great acoustic guitar demo’s to prove my point. There is something very special with the old Gibson Jumbos, it doesn’t really matter if it’s a J-45, J-50, Southern Jumbo or Advanced Jumbo, they all have that special booming bass sound. If you listen to any acoustic Jackson Browne, early James Taylor or even Bob Dylan you will understand what I mean straight away. There was a lot of Country players that favoured this sound before the singer and songwriters of the Sixties and Seventies. Two modern examples that I really like is Gillian Welch and Daniel Romano, he is actually playing something more modern like a Gospel but the bass is still there. If you listen to Dan Tyminski and hear his 1946 Martin D-28 I’m sure you would want a wartime Martin straight away but still, there is something special with the Gibson Jumbo sound. I’m not even sure if I would prefer a Gibson J-45 or a J-50, actually I really like the Southern Jumbo too with their fretboard inlays, so I guess as long as it’s old, worn and sounds like a Gibson Jumbo I would be happy. I mentioned earlier that I recently ordered a 1977 K.Yairi TG-40, which I have very high hopes for. I bought it straight from Japan and unfortunately it got stuck in the Spanish customs and has been there since the 12th of April. The Yairi TG-40 is a Guild D-40 copy, which was introduced in the Sixties as a competitor to Gibson’s J-45. The Guild D-40 became famous as the Bluegrass guitar for their even response over all the strings and I really like the sound of them, it’s actually not too far off from a Sixties Gibson J-45. With a bit of luck the customs will release my guitar soon and with even more luck it’s going to be an awesome Yairi copy of an Guild which might sound a bit like a Gibson.

Sometimes when I’m left unsupervised, especially on Sunday nights, I end up buying guitars that maybe I shouldn’t have bought, or rather that maybe I don’t really need. I’ve been thinking a lot about trying to find a 1970’s Gibson J-45, I can’t really afford anything earlier, but that would still set me back a at least 1500€ which is really hard to justify for a guitar player on my level. I’ve managed to track down the guitar sound that I love to Gibson’s old jumbo models, think Jackson Browne, and the J-45 or J-50 would have been ideal, I think, it’s hard to know without trying but from all the Youtube clips I’ve been listening to they all have a very similar sound. It’s that dry woody booming bass sound that is unmistakably a Gibson J-45. Now I got a Japanese made Guild D-40 copy instead, it wasn’t really planned but I couldn’t resist, or I got carried away, anyway, it’s mine now. The Guild D-40 has a lot of awesome qualities, it’s a proper bluegrass guitar and was built for their even response over all the strings. I trust that Yairi did a good job 37 years ago and even if it doesn’t sound like a Gibson J-45, I’m sure it will have a lot of warmth and good bass, just what I’ve been looking for. On top of that, it’s a freaking Yairi, I never thought I would be able to afford that and I’ve dreamt of a Yairi since I bought my first Japanese acoustic.

Kazuo Yairi

Master Luthier, Kazuo Yairi Dies Aged 81

I just found out that Kazuo Yairi died earlier this month at the age of 81. As I mentioned before, I would love to one day afford a K.Yairi and big reason for that is the philosophy of Mr Yairi himself:

Good materials are hard to find so it’s better to make guitars through limited production by hand instead of mass production. Trees are very important “precious” things so we should make good use of them. Guitars made with “heart” are the best use of trees.  Kazuo Yairi

I’m extremely happy with the two Morris I have and think that Terada is one of the better acoustic guitar builders in Japan. Having said that, I think everyone that is in to Japanese acoustics dream of owning a K. Yairi, at least I do. Unfortunately they are a bit too expensive for me, I’m sure they are worth it but you can get an old Martin, Gibson or Guild for that money. One thing that I really like with Yairi is that they use the year of the Emperor of Japan to determine the production year of their instruments, how awesome is that. See the list below.

When was my Yairi made?
By reading the number stamped on the heel block of your Yairi, you can tell in which year it was made. The first two numbers correspond to the year of the Emperor of Japan at that time, see chart below. The second two numbers refer to the month of production. Taken from The Fellowship of Acoustics

Martin D42/D45 Made in Japan copy

Alvarez Yairi 5070

I’m after a Japan made Martin D42/D45 copy. If anyone happens to see one for sale, please let me know. It doesn’t have to be a Alvarez or Yairi, Morris, Mountain, Suzuki, Aria and pretty much anything else would do as long as it’s made in Japan in the 1970’s or early 1980’s. However, it has to have the hexagon inlays and binding around the top and soundhole.
