Noah's Ark - Distortion M

Postby invictus » 05 Mar 2008, 10:16

to get along with the program, i'll post each model in separate threads.

for good image resolution, i'll attach the original *.tif file which can easily be opened with mspaint.

according to the designer, the "M" in the name means "Marshall" so it's supposed to be a Marshall in a box... see for yourselves! :D

Thanks!
How is this supposed to be a Marshall in a box? :hmmm:
Well, we shall have to build one and see. Maybe it is a good example of how you don't actually have to mimic a circuit (like those JFET amp simulators) to actually mimic the sound.

"Funny" circuit:

second opamp has a gain of 13.

1S 1588 diodes will clip at 1,3V ss. This means when they start to clip the second op long time ago will have run into the power-supply-rail.... perfect sound....

Hab das gleiche Problem - die Lösung dafür:
rechte maustaste drücken, save to harddisk und dann mit einem bildbetrachter anschauen.

Ok for our english-speaking friends:

I have the same problem (with all files) - the solution:
right click your mouse save file to disk and view it with your picture/grapchic program.

i think the Vref-connection of D4/5 is an error in the schematic.... i hope it ;)

why ? they are dc-decoupled with C9-C11 and from an AC-viewpoint C15 acts like nearly a short to ground....

Has anybody heard this pedal? I can't seem to find a review of it anywhere...
I wonder how it compares to other "marshall-in-a-box" pedals like the MI audio crunchbox.

Wow, that thing totally has that 80's modded Marshall sound! It sounds like I'm listening to a Ratt album! :lol:

Never believe what you here in soundsamples !!!!

A while ago I've downloaded a sample on a manufacture's webite for an OD with a tuned Marshall sound (sounded quite convincing) and then I discovered the same sample on another manufacture's site (but there as a sound demo for an Egnater tubeamp).

Is the doubt cleared on the schematic shared by oscarv77?
I had create a layout base on that schematic.

If anyone wanted to confirm that schematic / my layout...here you are....
Diode is 1S1588 as mentioned in the thread above.
I believe the IC is JRC4580D.
1 Meg resistor between 223 & 102 cap are not in the schematic. It was added in case there is a need for a pull down resistor to eliminate switch pop.

Would a regular 4558 work for that opamp?
