Ry,

I sure would like a peek at that schematic, if you get a chance to send it my way.

Thanks in advance!

There are many people interested in this schem (me too!), can you upload on a site?

Mark Hammer · February 19, 2004, 02:47:27 PM

Okay, I guess I'm in too. :roll:

If there is still space in the cc field, I'd like to take a look

Ry,
Please add me to the list as well.
Thanks!

OK, thanks to Ry, I have the schemos and have had a look. It's not too much more complicated than the Maestro Rhythm 'N Sound for guitar.

I suspect that we can reverse engineer the circuits back into something simpler for diy stuff.

Interestingly, the only phaser section I've been able to spot looks more like the transistor ladder style phasers than the ones we normally play with. This is good - I have a lot of phasers and have had many more over the years. The only ones I still have and use are the univibe and the MXR Fullrotor, which is a ladder based phaser, same circuit as the Little David Leslie simulator. Good stuff, if more complicated than we normally use.

It may take a bit, and I will need a look at the connection diagrams, but there is hope.

Ry · February 19, 2004, 05:18:52 PM

R.G.,

That's really great news! It's been a bit of a personal quest for me to get one of these (or build a working clone). I will send off the switch connection diagrams tonight. I have a lot of pictures of the outside of the effect that I've pulled off of the web over the last 5 years if they might help.

To everyone else: I will be emailing you the schematics in a few hours.

Ry

Hey Ry,

Thanx! mucho! for the Schemos.

Reminds me of the G-synth that Anderton built in the first issues
of DEVICE. Then there's the EH-Micorsynth.

Hey, do U have a full "head shot" of the unit?
U know, a straight-on jpg of the front panel.
the jpg U linked 2 and the one at Fulltone R far-away shots.
A clear FP shot would tell me the knobs and sw functions.
Right off it looks like a hi-Q vocal filter among a few other things.

Hey, thanx again for the monster bmps.
Good thing i have cable :lol:

Hey aron, think i got the hang of the emoticons!

thanx again Ry

Dan N · February 20, 2004, 09:14:42 AM

If it's not too late, I would love to see the schematic too!

Thanks!

Woe Dan!

Nice jpg of the frontpanel!
Thanx!

Boy, that schemo is so convoluted, Ry.
I've modified the contrast, and zoomed up,
then printed out 2 several pages and then
taped them together. Have trouble reading
some of the words/numbers on the schemo.

Anywho, when U breadboarded it, did U redraw the schemo?

I'm trying 2 follow the signal flow.

Dan, Ry, where did the guitar plug in?
tone

"animation", "format trajectories"???

Dan N · February 20, 2004, 08:58:36 PM

Perhaps someone other than Ry can send me a schematic?

ickystay@hotmail.com

Thanks,
Dan

Kazuo · February 20, 2004, 09:02:53 PM

Hello.Ry.
Please send a schematic also to me by mail.

dig_suck@yahoo.co.jp

Ry · February 20, 2004, 09:14:17 PM

Guys,

I'm really sorry about not getting the schematic out to all of you

...I did a mass emailing to about 6-8 people last night and it took FOREVER to send from my dial up (these files are BIG). I think a couple of the people I emailed bounced back because now when I open my mail, it starts chugging along for about half an hour, then hangs with only about 1/5 of my message content downloaded. I need to resolve this issue before I can send from my mail again.

Sorry guys, I will try to get this resolved as soon as I can...

Dan N · February 20, 2004, 09:53:28 PM

That's O.K. Ry, I sure understand the (ahem ack ack)"speed" of dialup and large files. We all really appreciate you trying!

Dan

toneless · February 20, 2004, 10:27:16 PM

Is it possible for someone to post this schematic on the net?I think it's a very interesting and rare toy...
By the way it's true that it doesn't has any ic's?

Jason Stout · February 20, 2004, 10:33:42 PM

If someone sends it to me I can have it posted tonight!

toneman · February 20, 2004, 10:37:32 PM

actually, there's a schematics echange discussion group @ YahooGroups.

Upload 2 Yahoo's drives.

Ry sent them 2 me.
My cablemodem didn't have 2 much problem.
i have resized. recaptured, and adjusted the schemos.

i use the Groups 2 xfer large files 2 myself soz i won't clog my
email box.

U all interested?
I'll upload the original and my modded if U want.
That way, U can load at your own *speed*.
Post here or PM me.
That OK w/U Ry?
LMK

Oh Kay,
I've uploaded Ry's large bmps and my smaller jpgs.

the doc is a copy of the NFO in the email he sent explaining
the switch connections and other questions.

goto
