The mod is an added "third channel" - a gain boost and tighter bass, for the br00tz. Done by Lickliter amplification. The mod is accessible in the back with a switch and gain control, as seen in the pics.
The speakers are not original, but one Celestion A-type and one V-type. It DOES have the og Drake transformer.
I don't have the og footswitch, but can offer a boss footswitch in its place.
