SRV in a Box?? (maybe)

[markm]

Just wanted to share this with the Board......a TS808 modded to be SRV sounding. 
I found it on a Japanese web-site and did the layout last night....it is UNVERIFIED but, check it out anyway!

Thats cool. Is there a schematic? Whats differant from the normal ts-808?

Yes.
However, It is not mine to distribute so I don't think it would be cool to do so however, it is a TS808 with some mods.

Look here and one can see some of the differences;

.... then just link us to the site ...... please ?

This is a spreading disease that I thought had left the board right now: layouts without schematics.
Maybe this is inspired by the continuing misguided ideas about copyrights and patents and all... if not I don't understand at all.
Why look at a layout that has potential extra flaws?

It's on a website but you cannot link to it? Come on!

Red alert, Red alert, Red alert...schematic request incoming, incoming

Well, I don't think it is that special. SRV = "stockest of the stock"-TS808 into light cranked Plexi.
You could do better by putting a light gain BSIAB behind a TS808...

What?  You can't understand the cloak of secrecy behind YET ANOTHER modded Tubescreamer?   

Geeeez!  The SRV sound isn't that tough to replicate anyway given a decent amp, a Strat, and a TS!

Maybe it's my misguided ideas about etiquette.

I will link to it when I can this evening to clear the air of any extra flaws......it's the flaws in the schemo that concern me though! 
In the meantime, one could always compare the layout to a regular TS schem and get an idea as to what's happening in this circuit.

the layout is incorrect. where does pin 1 of the mojo connect?

That was left out. I believe it goes to pin 4 of the "working" ...

Srv in a box??? Get 013guitar strings. Try to bend 1/2 tone, and quit the idea of sounding like him

Uh-HUH

don't forget to put bass frets on your guitar.

Love the jokes fellas but, please keep something in mind, this is not MY circuit nor do I have anything to do with it other than presenting the layout, posting the schem, and passing said info along.
I have not built this circuit as of yet though I intend to soon.
With that said, I'm sure the fellow from Japan that drew up the mods for this circuit was quite pleased with the sound of the circuit AND I'll go a step further and say that it probably does sound pretty good.
Please be aware too that this same kind fellow is the one who so kindly brought the beloved "Crunch-Box" circuit to the DIY community.
I'll bet many of you don't know that huh?
This kind Japanese fellow happens to be VERY knowledgable about electronics and I would would consider him to be around the caliber of RG/Mark Hammer ..........if THEY had done these mods on the 808 and posted it with "SRV" as part of the name of the box, I would put money on it that you'd be tripping over yourselves to post an "atta-boy" reply.
Funny that it works like that isn't it?
Politics?
Perhaps.
Before posting it I had thought about changing the name because I knew the "flak" it was going to generate from some of you.I should have changed the name and called it something like "Dr. Booger" which would have really tourqued a few of you up!
Out of respect for this board and the "creator" of this circuit, I left it in tact as it is against my better judgment.

Next time, I will know better I suppose.
In closing, I will say that I was under the incorrect assumption that I was actually contributing alot to this community by posting my circuit layouts, I'm beginning to think that I was wrong to assume that.
Thank you zjokka for making me aware of my shortcomings.

I've been plagued with PMs from people expecting me to de-bug their circuit they are building from my layout.
I get those all the time.
Once it works......they could care less.
The last time ANYONE ever thanked me for ANY of my effort here was Hiwatt25.......he sent me a PM to just say thanks for all the great builds. Hiwatt and ONE other person here have ever thanked me for anything I have presented to the board.
If it wasn't so sad, it would actually be funny.

Oh yes, and by the way.....if you search matsumi's pages you'll find lots of schems that are "not allowed" here! 

[QSQCaito]

Oh, It was not my intention to offend anyone. Sorry if I did.

My point was that(at least in my opinion) you can only get his true sounds using his strings as a very important component. And that if you put that strings it'd be very hard to bend and you would probably quit the idea of sounding exactly like SRV. There are also other parts involved in his sound as amp, and stompboxes. The thing was that FOR ME,the tube screamer is not the main part.

Sorry if I said somethign wrong

bye bye!

same here, mark, no offense intended.

[markm]

same here, mark, no offense intended.

Ya know guys,
I'm not offended by the jokes, I mean, SRV is in a box NOW isn't he??
Anyway, it's the general attitude presented here sometimes.
Not everyone has the desire to see a schematic, to some a schem means diddly-squat.
Some the layout is meaningless but one thing we as a collective group need to understand is, not everyone that frequents this board is an aspiring EE or a wanna-be EE.....some just want to build effects and I guess that's what my layout section is all about.
To many that come here, this is a hobby not a lifestyle!
For example.......I like women ALOT but, I don't want to be one!!
To some, analyzing the inner workings of a Ge fuzz circuit schematic is the be-all end-all of stompboxes, while others could give a horses pa-toot about some antiquated one-trick-pony circuit.
Bottom line;
Converting a layout to a schem could prove quite challenging and rewarding at the same time!

Please don't get mad: the 013 gauge strings, possibly bass frets, and associated playing difficulty are no joke.

I remember once I was tempted to move on to a heavier gauge, so I bought 011's instead of the usual 009's.  Huge difference.  There was definitely an increase in the body of the notes, something that wasn't achieved on lighter strings by simply turning the Bass knob on the amp or Equalizer. Playing difficulty increased with regards to bends quite a bit, and I had to recalibrate my guitar. Finally I settled with 010's because was something my guitar and I could better manage.

--------------------------

Regarding the schem, there is nothing too different with respect to a TS-808 to make such a difference. Perhaps the most notable difference is in the output buffer, however other key aspects like 47n/4.7k (720 Hz bass rolloff) in the first opamp, or the clipping diodes, or the opamp type, or the tone control sections are pretty stock. Interesting anyway, and quite easy to try on an already DIY TS. Thanks for posting the schem.

--------------------------

Please notice there is an error in both layouts (linked in first and third posts). Opamp pin #3 has no resistance to Vcc/2, and is capacitively coupled only.

--------------------------

Cheers to everyone, and let's keep the good DIY spirit!
