Do I have a Prototype JP7?? EBMM guys, help me!

I already asked this to a few persons over here, but we could not find some answers yet, so I decided to make this thread. (I just copied the text from a mail I wrote recently.)


Sooo...

I just purchased a JP7. Mystic Dream, fully loaded, great guitar.

After I received it, I noticed that there are a few slight constructional differences to any other JP model I've seen before.

I posted the serial number in the identification thread over here, but Dan from EBMM told me he could not find the number in their database. He assumed it was made in spring of 2001.

Then Pete DuBaldo offered his help and told me where I could find the work order number (as most of you might know, it's a white sticker under the bridge pickup). I mailed it to him and he showed this number to another guy of EBMM he knows, but even that number doesn't show up at EBMM's databases, too.


So, first thing to state: I have a guitar with weird serial and work order numbers.







But as I said, it's not just the numbers that are a bit strange, there are some slight differences in the construction as well. I have taken some pictures of all the small differences, you can find them here (click for larger images):


1. The signature is located nearer to the tip of the headstock than usual (but Ernie1966 told me this just happens on some Pets, so that's not that special):




2. The "Made in ..." label is printed in golden letters and it is a bit angled and aligned with the 5 upper tuners (Again, Ernie told me this was the way it was done back then, so it's not so special, again):




But now, here they come...:


3. The tremolo base plate has no "Music Man" label engraved:




4. The preamp box has a different shape and it has no labels on it at all. No labels on the piezo eq screws:




5. ...and no labels on the output jacks:




6. The battery box is located lower, it is placed nearer the lower strap pin. Notice the cutout in the upper right corner of the preamp box (otherwise they'd overlap each other):




7. Another thing I noticed yesterday was that in the middle position of the magnetic pickup switch, there is hum. So it's not humcancelling, which could just be a wiring issue the previous owner might have done. But the switch seems to be untouched after being wired up in the factory.


Well, that's it for now.


You see, the strange points are 3 to 6. ^^

Ernie1966 told that he has two of the first 100 JP7's and both have the normal labeled and sized parts on them.


Let me point this out: I have absolutely no doubt that this is a genuine EBMM guitar. It feels, sounds and plays perfect and all the electronics including the piezo work fine.

So, more and more it seems to me that I have some kind of a pre-production model or even a prototype in my hands.


I don't know whom to ask anymore, maybe you guys can help me with that?

What guitar is this??

Let me know what you think. Especially you EBMM guys, please help me!

Thanks! :)

Felix


P.S.: And thanks to Dan from EBMM, Pete DuBaldo and Ernie1966 for trying to help me so far.

Felix,

Did you try taking the neck off to see if there are build dates printed on the neck and body cavity? You can do it, it's not as scary as it seems. I'll take the pic you asked for and send it to you tonight.

(It's funny, I took the neck off the proto Pet I have last night, 'cause there is no record of the build date at EBMM. No luck, nothing stamped or printed in the pocket or on the neck.)

ernie

Maybe BP can shed some light on this matter.

Are we 100% sure its not a real signature? It looked a bit different to me at a glance.

The sig. is good. It's the early gold silkscreen they did on the MD Pets and it's fading.

Also the build codes under the pickup look correct for the guitar. They are 971-Pet 7 w/piezo bridge, 09-Mystic Green, 21-Rosewood Matching Headstock (No Shield Inlay).

Hey Ernie,

umm... the build codes mean it has ho shield inlays, you say...?

It in deed has the JP shield inlays! (And btw, they're made absolutely perfect, no sign of a filler around them, great work, EBMM!)

So what would be the correct code for the inlays? "01" instead of "00"? And does the "H" on the white sticker have any meaning?

I did not get around to take off the neck, I'll do this with the next string change. Unfortunately, I don't have any new strings right now, so this might take a few days. :(

I'll measure the distance from the battery box to the trem cavity cover today, I just forgot about it yesterday, sorry.

Sorry for double-posting.

It was a bit hard to photograph the signature, sorry, because, just like Ernie said, the golden signature and EBMM logo on the headstock are a bit faded. But it's just like any other printed silkscreen logo I came across during my search.

So no, it's definately not written with a pen, it's the printed silk screen logo.

Hm... writing this makes me thinking about something. Maybe there used to be another neck w/o shield inlays on it and this is a "post-first-100" replacement neck? (Is that understandable...? ;) )

I believe only the 1st 3 sets of #'s in the build code really mean anything to the Pet model. The third set of #'s on your Pet is 21-Rosewood/Matching HS, 26 is the code for Rosewood/Inlay/Matching HS. The forth set of #'s,
00, I believe means no pickguard. So your Pet's body should be matched up with a dot inlay neck.

When EBMM replaces a neck they replace it with a neck having the exact same specs as the old neck. So if your Pet went back to EBMM for a replacement neck, they would not have "upgraded" it to shield inlays.

About the 1st 100 hand signed Pets; I have never seen one without shield inlays and believe that all of the 1st 100 had shield inlays.

The mystery continues.

Alright, thanks for the info!

Don't get me wrong, I don't think this is one of the first 100 Pets. It might be that this is a pre-production body with a neck that was manufactured after the first 100 Pets. (Hence the printed silkscreen signature)

But I cannot know for sure until someone tells me what it is :(

The mystery continues.

Big Poppa, Dudley, where are you...?

So... Ernie was asking me about the measurements:

The piezo module is 7,2cm x 5,7cm x 3,2cm (inch: 2,83 x 2,24 x 1,26).

And the battery box is 1,6cm below the trem cavity cover (inch: 0,63).

On the Pet 7, the battery box is located approx. .9 cm. below the trem plate, on the 6 string it's approx. 1.2 cm. So your battery box is much lower than normal.

The measurements of the piezo mod are the same except for the part with the jacks, that measure 2.8 cm., so the mod. on your Pet cuts into the body more. When I look at your pics it looks like there is less body wood between the piezo and the face of the guitar.

Looks like if you wanna get some more info that neck has gotta come off.

Thanks Ernie!

Okay, so it's not just an unlabeled Version of the piezo box they're using now, it's even a bit larger.

I really have to take off the neck soon. I ordered new string and expect them to arrive in the next few days. I really hope I'll actually find something under there... :eek:

Still no EBMM employee here? :(

Greetings!

This is a rather strange Felix.

Could be an after market Piezo hence the difference like new trem (with no logo), difference position so on so forth only unscrewing the preamp can show if the guitar is painted underneath.

It is painted, I already unscrewed the preamp because I was thinking the same. It is definately not after market, it's factory installed.

And as far as I know, you cannot buy the trem as a replacement, it is EBMM OEM only. I think the manufacturer is Schaller, if I remember correctly.

Sadly, no one at EBMM chimed in to this thread. The piezo pre-amp box on his Pet has slightly different dimensions than the production box. It cuts into the body more. The battery box is def. lower. All these different routs point to a pre-production, quasi-proto body. The build codes on the body do not match up with the shield inlay neck. Maybe Felix should change the title of his thread to catch the eye of some one at EBMM, something like:
"Do I have Prototype."

any news/update on your guitar Felix ?

Hey 3minutesboy,

well, I did not have the time to take off the neck yet. Plus, I'm still waiting for my new strings to arrive, so I have no news about it at the moment... :(

Hey Ernie,

you're writing exactly what I am thinking about it.

I'll try to change the title now, maybe they'll look into this thread then.

EDIT: I can't see a way to change the thread title, I only managed to change the title of my first post (which was the thread title), but the thread name stays... Anyone knows how to do this?

If a moderator reads this, could you please change the thread title to "Do I have a prototype JP7?? EBMM guys, help me!" ? Thanks!

Cheerio!
Felix

Hey guys

The serial number does not come up in our database. Neither does the work order number. Last week Pete asked me about this and I told him the same thing. It is probably a prototype of some sort. When we have a chance we can ask Dudley to take a look at the pictures and he may have some additional information. Keep in mind that he is very busy these days working on fine tuning some of the instruments you've been teased with the past few weeks.

In the meantime, how does it play? How does it sound?

Hey A.J.,

thanks for chiming in! :)

So you are the one Pete talked to, alright!
It would be nice if you could give Dudley a hint, maybe he knows something about it.

Btw, do I understand that right that Dudley is your EBMM electronics developer...?

Oh, and yes, it plays and sounds just like a mystic dream... :rolleyes::cool:
Great guitar, no doubt.

I'm still trying to lower the action, but I think this is kind of useless at the moment, because it still has the strings on it which the former owner has put on. I won't get on with this until I have restrung it with my choice of strings.
