Runoff Groove Omega Layout

[96ecss]

I just added a PCB layout for the Omega Booster to my gallery. I haven't built it yet, but it's node checked and should work fine. Please let me know if you find any errors in the layout. As always, comments and suggestions are welcome. http://www.aronnelson.com/gallery/v/Daves-Layouts/Omega.gif.html

Hi Dave,
Looks perty good! 
The only thing I can see is that Lug 1 of the "Range" pot should connect to R2 and Lugs 2 and 3 connect to Ground.
Have a look;

Hi Mark,

Thanks for checking it out. I wasn't sure about the range pot, but on the perf layout on the Runoff Groove web site, it has Lugs 2 and 3 going to R2. http://www.runoffgroove.com/omega.html. It's also that way on Gringo's PCB layout although he labeled the 22K resistor R1. http://www.runoffgroove.com/omega-pcb.pdf

I'm not sure which is right. I have alot of faith in your layouts as well as the Runoff Groove layouts.

I've got Range 2 & 3 (the 500k pot) connected to a 22K resistor on a working-but-bagged build.* I've got no build notes on it, but it looks like the ROG perfboard layout. If I recall, I had it on my board for a while tweaked to the Rangemaster side of things - 7.1V is written on the bag, and that stirs the memory. I may even have been trying to see what happened if you treble boosted a treble booster...**

MarkM?

*If I build something I like but I'll come back to it later, or it was on my board but "superseded", I bag it up so all I have to do is slip it into an enclosure again later. Of course, I rarely ever get around to using it again, but sometimes, every now and then, I drag one out...

** So, I do strange things.

Edited for gross spelling mistakes.

Okay.
I could be wrong too but, I think I remember changing this on my layout when I built it but, Who knows?? 
I went looking for mine to see but, I think it was recycled......
Couldn't have been THAT good!!    I can be pretty Finicky when it comes to Boost circuits.

You can wire the pot either way depending on whether you want the full-range or treble mode to be in the fully clockwise position.  In my build, I wired it as shown in the perf and Pablo's PCB layout, which goes from treble to full-range as the pot is turned up.  The case can be made for the treble mode being fully clockwise, since that's how tone controls work, so it is a case of personal preference.

Thanks for the replys! I can see benefits of both ways to wire it. I think I like the original way of full range boost as the pot is turned up.
