1965 Mory Jazzmaster

Post by sleepkid » Sun Oct 19, 2014 1:36 am

Ok. So, I thought I'd finally open up the lid on the Mory Jazzmasters. There are one or two other Mory Jazzmasters floating around on this forum, but I thought I would present the kind of be all/tell all as I present my ugly/beautiful 1965 Mory Jazzmaster (please note - I play 'em, I don't coddle them, and I don't refinish them - if they're mine.)

So what is a Mory Jazzmaster? Mory is the nickname of Moridaira Toshio, who went on to found the very successful Morris guitar company. He was also responsible for the production of H.S. Anderson line of guitars (designed by Hidesato Shiino, and made famous by Prince and his Wildcat Telecaster). However, before he did all that, Moridaira ran a small company called "Mory" which made guitars in a small warehouse (and this could mean large garden shed really) - reportedly behind his house - in Tokyo from roughly 1965 to 1967, at which point he launched the Morris brand. There are no Morris Jazzmasters that I know of. These guitars were handmade. (Another famous handmade guitar line in Japan were the Voice guitars, made by Mr. Iwase who originally used to work for Teisco). The Mory guitars are a little bit unusual in that they are of better quality construction than the factory guitars being turned out. The body on my Mory is actually 3 pieces of Alder, which is just about unheard of for mid 60's Japan, as most guitars were either made of Luan ply, of Mahogany covered with a veneer.

Image

It says "Handmade - Mory High Quality Electric Guitar - Excellent Design - Wonderful Sound - Exceptional Finish - 32,000yen" - so, a little over US$1000 for 1965 Japan. Note the rocker switches instead of a toggle switch.

It's just about a dead on copy of a Jazzmaster, with a few minor exceptions, which changed throughout the years. The rocker switches being one, eventually being replaced with slide switches, and then a toggle switch. Original tuners were 6 on a strip I believe. Also, the tremolo arm changed from the October 1965 catalog (tremolo in the picture, and on mine) to the April 1966 Catalog (tremolo on the other Mory Jazzmasters posted here in the Offset forum, which is more Jazzmaster-esque, but still unique). The original pickguards on these were thicker, and two ply. These guitars were shielded at the factory, and the shielding was actually fairly well done, consisting of actual strips of sheet metal, as opposed to a foil of some kind.

Which brings us to the one I found. It had been long abused, and unfortunately was no longer in 100% original condition. Someone had changed out the tuners, the original pickguard was long gone and replaced with a Jazzmaster pickguard (complete with Krispy Kreme sticker for some reason), and of course that meant no more rocker switches. Original bridge was gone. Also, the tremolo cover was missing, revealing the incredible (as in "I can't believe that thing works") tremolo tailpiece. They'd also decided to add some original inlay work - using, a pick? what? Still, when I got it, it was playable. And despite all the dings and scratches, has one of the best sunburst finishes I've seen:

Image

Image

Was incorrectly strung up - but I can't really blame the person, the door hinge tremolo/tailpiece really doesn't look like it should work at all:

Image

But aside from the goofy tailpiece, and a slight route for the original Mory bridge, bodywise it was a near perfect match when laid out next to my long suffering (and I do mean suffering) 1959 Jazzmaster:

Image

Necks are also the same, though the Mory has a nut that terminates the fretboard, unlike the Fender nuts which are inserted just before the end of the fretboard. The headstock on a Mory is more akin with a CBS headstock (ever so slightly thicker) as opposed to the Pre-CBS headstocks.

Unfortunately I can't tell you too much about the pickups as the ones in mine had been rewound, but they had used the original bobbins, and they dropped right into the 59 Fender pickup covers just like they were made for it.

Since the ones in mine had been rewound, and were a bit unbalanced, I took them out, and substituted in a pair of amazing sounding mystery pickups (which are a story unto themselves - but for another time) from a 1960's bizarre Japanese guitar (kind of a crime to remove them from the original guitar, but the original guitar didn't have a construction to match the majesty of the pickups). Also had a tremolo arm made which is longer than a standard aftermarket Jazzmaster arm, because the tremolo system is about 3cm back from where it would be on a Fender. Eventually will have a new pickguard made for this which will match the original dimensions. But other than that, this is pretty much how I'm going to play it:

Image

Beautifully ugly. But sounds and plays great.

Image

...and yes, it works. I prebend the string ends a little bit, hook them over the pegs, and then use a short stubby flathead screwdriver to hold them in place while I tune the string up to tension. Once they're on. They stay on. I've even tried to make them come off, and they won't. I can't believe it works.

Anyway, just thought I'd throw that out there.

that thing is so cool...
along the years i've become a fender purist, but this guitar is pushing me the opposite way...
those PUs look awsome... please tell us more about them...
that is a great save! congrats...

opposite here! Total oddball nut, and I don't really understand the apologies. It's not 'ugly' in the slightest! Beautiful guitar, and the trem isn't goofy...

;)

If it were mine I'd try and put it back to 100 percent original...guess those trem covers don't turn up? Rocker switches could be found I guess...

That is the most insane trem ever; can't wrap my head around the physics. It looks like an optical illusion. Also, that's the largest screw head I've ever seen. What is its function? Trem lock? Panic button?

Yes, please tell us the story of the pickups. With close-up pics!

Thanks for the kind words.

...and yes, the tremolo on the guitar is completely nuts. I'll have to take another picture of it. The spring in the cavity doesn't go up and down, but actually pushes against the end of the guitar. Also, the arms pitch can be adjusted via a hex screw. You can loosen the arm assembly and rotate it around the shaft (but not while there is tension on the strings.) In fact - now that I think about it, it might even be possible to rotate the shaft around when stringing it up so that the string ends point down, or even face front. I haven't tried that yet. The gigantic screw on the tailpiece there originally held the tailpiece cover on (look at the other one in this thread, still has the cover) - it runs straight into the body of the guitar, and also holds the tailpiece down - as if the other 8 screws weren't doing the job.

The pickup story. Ok.

The pickups are from a mystery guitar. The mystery guitar itself looks great. Here it is in it's original state:

Image

Looks awesome right? Unfortunately the body is roughly 7-ply, and 70% of the screws were rusted and snapped off, tailpiece is no longer stable, some points on the pickguard are broken off, cheap tuners, etc. and while the neck might be ok - guitars of this build quality take a lot of work to get to a playability which is usually average at best. I love the pickguard, I like the design, but it needs some work... (Still have this BTW - can't decide what to do with it.)

(Oh - and speculate away, but no one knows who made this guitar. Lots of theories about it: Zen-On being the most popular guess - same tailpiece - but I met one of the gentlemen who worked for the company that made pickups for Zen-On back in the day, and he said "No" - also, while Kawai had a somewhat similar headstock shape on some of their guitars, haven't been able to match it up. I've even met another person who has owned one of these - sold it unfortunately - and no label on his headstock either. Somewhat unusual switches on this guitar. A true mystery.)

However, the pickups in this guitar are a completely different story.

Image

They are very serious pieces of hardware. Why? Because they have 8 magnets! 6 Alnico magnets - of slightly larger than normal diameter (north up) through the coil, and flanked on either side by ceramic magnets running the length of the pickup and facing south up(!). All sit upon a single shaped copper plate. The neck reads 9.92k and the bridge reads an even 10.00k - the things that look like adjustable pole pieces on the sides are actually screws which make contact with the ceramic magnets and hold it down.

Image

Though I can wind and repair pickups, and have a basic understanding of the physics behind them, I am not an expert. I've asked three different pickup specialists about this, and no one can agree on exactly what is going on here. Was told by one of them that it was a "failed design".

Failed design or not, these pickups sound very, very good. And so I committed the crime of separating them from their original host and putting them in the Mory.

I've been working on getting together materials for recreating these pickups, just to see if I can do it. However, would really need to determine the gauss and composition of the alnico magnets and I don't have a way to do that presently.

As they were, the pickguard and body of the guitar had to be modified very slightly to accommodate these. However, if I were to recreate them, making a ring that would be a drop in for Jazzmasters would be quite cool. Project for a future day.

Wish I understood magnetic fields... What would it sound like if you flip the ceramic magnets to be north up?

i cannot tell if those are a failed design or whatever...
they sure have an unusual high output so i expect them to have a very strong and rich tone...
plus they have a certain resophonic look that makes the guitar look real cool...
a little jealous here...

As an experiment, it would be interesting to see what happens if those side magnets were removed. I suppose you've already checked it all out, but I'd wonder if that bottom plate is copper-plated steel, being charged by those magnets along the sides, and the magnets inside the coil are actually slugs connected to the plate. Just a thought, I could be completely off base here. That trem looks interesting, looks like it would function like a Bigsby. This is a great thread- thanks for posting! Very cool guitar, I love stuff like this. 8)

Awesome guitar and background story, sleepkid. Thanks so much for posting in such detail. Always nice to learn more about Japanese guitars.
Just out of curiosity, are those Greco tuners on the Mory?

I tried this at one point, and the sound was a little less sharp and defined in my opinion. As it is now they have a wonderful clarity even at a high output, and especially in the middle position a very full and round sound. (Talking about sound is always difficult.) Having my clean amp reworked at the moment, but maybe when I get it back I'll record some sound files.

The copper base is conductive and magnetic. So, yes, I guess it is copper plated steel. But the slugs in the coil are alnico magnets. I've had the coil off of the base to test this. I haven't played the pickup without the ceramic magnets, but since I know flipping the polarity of them does affect the sound somewhat, I'd imagine that removing them would also have some sort of affect. What exactly they are doing is a bit of a mystery, but they are doing something. I suppose removing them would allow us to determine how great of an influence they have on the overall sound.

Good eye. They're from a late 70's Greco. I didn't put them on there. Originally these guitars had six on a strip tuners I believe, and later the open back interlocking angle tuners that were common on a lot of guitars in Japan. Someone upgraded it to the Grecos. I am of half a mind to leave them on there as they function find and contribute to the over all partsmaster-ness of the guitar, but I have a set of Gotoh Kluson type tuners that would cover most of the holes made by the Greco, and bring it slightly more in line with a Jazzmaster.

I'd imagine the coil without the baseplate and extra magnets might sound more standard and "Fender-y"- the base and extra magnets must reshape the field in some way similar to Supro pickups and some gold foils. Yours must form a kind of w-shaped "double horseshoe" magnet, or something like that. It could be interesting to remove the magnets one at a time and test too, one magnet removed would get them closer to the configuration of those other pickups I mentioned. Just the base by itself without the extra magnets would have an effect too, I guess. (Not that I'm any kind of expert on this stuff, just becoming fascinated by it.)

I'm gonna run the risk of sounding like an internet dick here, but put both of these back to original immediately! Two very cool guitars, that I'd be glad to own in original/near original state

Not a fan of 'partscasters' if it involves taking 'way rarer than fender' 50 year old guitars to bits. I think people often underestimate how rare some of this stuff is. Fender made thousands and thousands of Teles, Strats, Jazzmasters etc- sometimes with stuff like this, it was a one of run of 100 or so. 50 years down the line, there are so few of them left, it's (imnsho) a bit of a crime to part them out.

The list of issues you have with the second guitar is pretty low level stuff. Stick some quality tuners and some new screws in there, maybe a bit of a fret level. Who cares if it's made of ply.
