DOD FX10

FX10 schematic

I know the Bifet 410 is done, but the FX10 has a different eq, with the buffering removed it looks like a good stripboard candidate.

I was looking at that one. I might take a crack at it this week.

Hey Denmorin,

I got the proper schematic for the FX10 less the switching system. I'm not sure who had posted it online. Looked ok. To be sure I bread boarded it. And it works fine. I have never played one. But it does sound pretty good.


I'm in the process of laying it out for vero. And should have something posted here this week I hope.

I have an FX10.   I can do some gut shots if need be but I don't have any time the next few weeks to do a trace or inspect components.

[Denmorin]

Ahh shoot, I did post the wrong schematic.

Check out the build docs here: http://www.griffineffects.com/store/projects/195-bifet-preamp-pcb.html

There is a stripboard layout included, but it's HUGE.

Here's the schematic I used. I did test the circuit and it seems to work well. I have a vero layout I'll post today. Unfortunately it's big and ugly. I'm sure someone here could probably rearrange some of the bits to get the size down some. But I think it should work. Circuit is good, vero unverified.

sorry forgot the link to the schmo

There was a mistake in my previous layout.
If you've already built that check the last post to correct it.
This is the new version.

[iggy]

thanks, that looks so much nicer than my attempt. i was struggling with this one.

[Denmorin]

I finally got around to building it. It passes signal and the tone stack does something, but it's really quiet, like it's cutting the signal rather than amplifying it.

[Alex]

Did you build my layout?
I've just realized there is a mistake!
I'll fix that but to avoid major changes you can remove the pin 5 link and run a second wire from Level-1 to pin 5
Sorry about that.
Let me know if it works!

[iggy]

I'm interested in which layout you built also. I am planning to build one for myself. Not sure which one I will build. Alex's design looks so much nicer than mine. But if you used mine let me know, so i can fix the issue.

Hi Iggy!
There are a couple of mistakes in your layout:
R12 should start at pin 7 instead of pin 8 and the double link at row 14 should be a single one going from "a" to "g".

[Denmorin]

It was Alex's layout.
I haven't tried the fixes yet though

Hey Alex,

Thanks for looking it over. The double link was just a random dot put on the page. Not sure how I did that. I'll fix the other issue. And give it a build. I built it on a breadboard. It does have a nice thickening effect. Not a ton of volume. But that may just be some issue with the build.

Anyone that has one of these have any feedback on what it does and sounds like?
