Wiring mod on DF to bypass preamp in mag position?

Long ago on the Parker forum some nice person posted instructions on how to rewire a DF so that it would bypass the Fishman preamp on the mag only position and utilize the preamp in the other two positions.

It identified which wires to reposition by color.

The problem is I have the later Ghost piezo/preamp, not the Fishman. I don't know if the colors of the wires are the same and even if so, if the same mod would work.

I wonder if anybody knows how to do the same thing with the Ghost.

I don't use the piezo that much, so it seems that using a battery most of the time when I don't need it to be a waste of the Earth's resources. Plus if the battery fails on the gig, I can finish the gig without having to dig through the gig box to get a new battery.

Thanks,
Notes

Hi @Notes_Norton! I think having the Graphtech Ghost system actually simplifies the issue to some degree since the company still sells/supports this technology. Here is their website:

I did ping them about something Fly-related a year or so ago and received a quick response.

Hey Notes!

I was the nice guy! Lol!!!
Here is the diagram. This works VERY well. In fact, I liked the sound better without going through the preamp because the pre introduced a little bit of hiss which translated to a lot of noise with high gain amps.
So here is the diagram. Enjoy!

This is great. I think I will do it almost immediately.

Are the wires the same color for the Ghost preamp?

Is it the same preamp?

I hate to try it if there is a chance of me screwing it up and not knowing why I screwed it up.

And yes, you were a nice guy for sharing.

Notes,
Less savvy than me on wiring things would be hard to find, and I did it without issues.
The colors were the same and this is for the ghost preamp. I don't have the guitar anymore.
Dive in!

That might be me :D

We're out of gigs since St. Patrick's day and probably for at least a year due to COVID so this is the time to try something.

Thanks again,

Thanks again!

I'll be nervous, and take lots of pictures so I can get it back the way I found it "just in case" :D

Is there a diagram like this for the Fishman preamp? I have a 2005 Mojo I am tired of killing the batteries in.

Yes, @WKG; the passive diagram is available on this page.

Thanks Vince

It looks like the Point to Point with Passive Point to Point with Passive Electronics? It's a little hard to peg the actual switch wiring in that one. I ordered the Dimarzio EP 1111 4PDT as well as the two Allied switches which are on/on/on and on/off/on, both dpdt, figured I'll use what works and toss the extra in the parts drawer.

I was able to find some of the posts from the old Parker Forum via the internet wayback machine but not diagrams. I can wire standard pickups etc but the Fly is more complicated than I am accustomed to...
