DR Mid Boost Mod

[Heady Jam Fan]

I know this has been discussed a fair bit, but I am working on selling a guitar that I don't use enough anymore and I will be able to fund a beat up SFDR + some mods with the money.

My understanding is the specific mod on Trey's DR is not in the inter-webs, but wondering if anyone has a mid-boost mod replacing their Vibrato channel that they like and if they could describe any of the technical aspects, or if they have a schematic for it?

Thanks
Jon
