super twin 750 missing

The Matsumoku semi hollows tended to have MMK61 pickups, rather than the MMK75s, which seemed to be standard fitting on the likes of the Westone X350/390… 
… however, I wish you luck finding either as they’re about as rare as chickens’ lips!!

Rainbows have MMK75's,  Session II's have 61's

I do have a set of MMK53's going spare if any use to you. Same wires as the Rainbow.

Thank you for your answer, I was thinking the super twin 750 as describe in the spec were mmk 75 with 4 wires for the PEQ system, I've seen some mmk61 but just with 2 wires, I'd like to put back the original PEQ system so I need a four wires system.
I saw some howto to convert the 2 wires humbuckers into 4 wires, so I think I will buy them and try to make it work
The deal for the guitar is not totally finish (the guitar is not into my house yet) so I wonder a bit...
I think these two pickups (61 and 75) are very closed so I think I'm going to follow your advice, it's the better way to be next from the original

Does the Rainbow you haven't got yet have the PEQ controls?

I've a untouched Rainbow II for sale if your interested?

Cool! Didn’t know that; thanks, Damian!

Thanks to both of you, and sorry for the late reply
I think the best thing to do is to wait the delevry of the rainbow, and like you said Westbone to see if the PEQ pots are still there...
I buy this guitar online and the guy didn't know anything about it, it was his father's one
I think I had it for a good price, and that is why I decided to buy it, even the rainbow was modify
I just hope the guy send it to me soon, and then I will come back to tell you
I play reggae, bossa, and I want to start playing more jazz, I hope this guitar will be good for that
I'm french as you can see my bad english

PEQ tone pots are not push/pull they have a detent in the middle position and are a stacked pot, one on top of the other. That should be easy to see via the F hole.

I have a bridge in chrome if needed and studs.

Hi Westbone,
I didn't felt any detent in the middle of the pot, I think I'm going to disassembly all the staff probably this week, I hope I will find them in. (I will post a picture)
I don't see weel how they are via the small F hole
Thank you for the bridge but in fact I've got one (not in the picture) which is in a very good state
I can't understand why they have changed the pickups to put this bad quality ones... at the opposite the guitar is in a very good state, it seems brand new
What do you think about the year's built of this guitar, why there is no serial number, for me it could a post 1985 one ?
What do you think about that ?

The PEQ system is there ! Good news, now another challenge began, I've found a MMK61 2 wires that I will have to convert in a four wires one, the MMK75 I founded is a 4 wires one, they are both neck pick up but I think it will be OK, I think I will use the 75 in neck and the 61 in bridge but I don't know what is the best to do.I upload the pictures of what I've found in, never seen something like that !!! I will try to do better....

I've found some numbers in the body, but I don't know what it could means

As far as we know, those numbers are most likely an internal manufacturing reference, they have nothing to do with dating or serial numbering.

They probably identify such things as which neck goes with which body, the colour finish, etc.

Hmm, are you sure you want to do that?

These pickups are now 40 years old and it might not be wise to open up it up and attempt a modification. Is a single coil option really necessary, especially if you intend to play jazz?

Many of the MMK45's have suffered from winding "rot' with one or both coils breaking all by themselves. Ask me how I know.

If others in the series are similarly fragile, you could end up with an unusable pickup.

Barry,
In fact it's not for single coil but to use the PEQ tone system, I don't know if I can keep one in a 2 wire config and how to wire it on the PEQ pots ?

I'm not the guy to ask!
Damian, what do you think?

Of course it can be done.

The Rainbow II wiring diagram is on the website.

Thanks Damian.

I was attempting to provide the link but apparently the website is buggered up (again) and not connecting to the database.

Give it a little time and perhaps Keiran will correct the problem soon.

I used the wiring diagram of the rainbow2 to make the "Harness" you can see in the picture I've already posted and it's very usefull.
But in this diagran we can't see the conexion to the coils, I've seen in the wiring diagram of the concord bass, few indications that will help me.
The pick up I want to install in bridge position is a neck one so I think I must turn it for 180°
I think the colors must fit like this :
Black : North start
Red : North finish
Brown : South finish
Orange : South start
Is that right ?
I will the recieve the 61's pickup today or tomorow, and I will open it to see how it's look like.
