Snarling dogs distortion pedals?

grolschie · Post by **grolschie** » 16 Jul 2007, 21:48

Is it true that a few of these (i.e. Black Dog and Tweed E Dog) are simply EH Hot Tubes clones with a few tweaks? Any schematics floating around? I see that these pedals are now discontinued. The videos didn't inspire me to want one, but reviews seem interesting enough for me to want to know more. Thanks in advance.

I don't know anything about their distortion boxes, but a friend of mine has one of their wahs..... maybe I could take some pics and trace it?

Their Whine-O-Wah sounds cool. Mixed reviews though. It'd be interesting to see if there's any mojo there. Twin inductors and lots of knobs.

I bought 2 (for the cases) and traced them a very long time ago.

Hmmm. If I could just remember the file name...

Edit- found it:

I'd draw it differently now, but to hell with it.

Hey. Thanks for that!

So the only difference between the two models is an IC?

No, there are some different cap values. Look for the *'s.

Sorry. My mistake. Thanks for that.

Now - where else would you get such a quick reply ( with no b**lshit snide comments or threats)

- many thanks Dan N for sharing with us

Cheers

Exactly!

In principle an EH Hottube (old) clone...

@Dan N
Do you have any guts ?
The input opamp wiring appears a little bit suspect to me.

I could only find one:

The other used AVX box caps. The zenor is 5v6.

Thanks for the guts !

I wouldn´t believe it if I wouldn´t see it. The transistor in the schematic said to me: "Take care, I am an 2SC 9013 i am normally used in chinese products...". The rest looks the same.

The opamp is running on 5V only, same as the C-Mos.... and the second stage only the chinese gods know for what it is good.. with a 10µF in the feedback loop...has only 800 ohm at 20 Hz, so only DC-offset will be amplified if any....

I willl redraw it in the next days for your archive....
How was the footswitch wired ?

Chinese all the way. Is has that awful solder that will not reflow without flux or a dab of good solder. Look at the pads wrong and they jump off the board.

Sorry, I do not remember the switching. I have a feeling it was true bypass using a brown Fulltone switch.

There was one more in the series (Doodoo Dog?). It would be nice if one showed up so we can kill off all three with one schematic.

Anyway, thanks AG!

There was:
* Black Dog
* Tweed E Dog
* Blue Doo
* Very Tone Dog

Hey, there is a Blue Doo on evilbay:

I own a Blu Doo, but it's an old one, steel-finish, two-knob version. I used to play it a lot while I was in a Stoner Rock band, it does sound fat.
Looking inside it seems to be a version of Craig Anderton Tube Sound OD, as rumoured.

Went ahead and bumped this thread since there was a bunch of info already here.

I got the Black Dog in a trade, and I like it, but it makes a lot of hissy noise when my guitar volume is not up all the way to ten.

Is there any way I can make this thing useable by, say, upgrading the caps. I know somebody before said it's hard to de-solder the thing.

I saw a post on another thread that recommended removing c10 and placing it between pin 5 of IC2 and GND.

What would that improve?

Do you have a link to the thread?
