Lee Jackson Metaltronix Amplifiers

[Libernox]

I am still interested in installing this mod in my amp. I have it all planned out, but wanted to know exactly how much gain the extra gain stage gives.

I have seen added gain stages in schematics of amps and other mods, such as Egnator's Modzilla, and the Laney AOr amps for a couple examples. These mods usually add the gain stage right after the input. From the looks of the schematic of the Lee Jackson Mod 1 it appears to be placed further along the preamp circuit.

The audio at the end of the DVD really didn't show much either. Can this mod go from stock 2203 style to raging extreme metal and all points in between? I would very much like to get rid of having to use any stomp boxes for gain(I play extreme metal).

Anyone have any clips?
