Rooted, rooted terminal, etc -- anyone know which system files and values I need to edit specifically, to edit the volume range and volume stepping?

Nebula 3.9 ROM, but I'm assuming the files are the same regardless. I tried the xposed volume+ module, and it adjusts the steps, but scrambles the dB settings in the process apparently.

So, does any one know which files and settings i need to edit to adjust volume stepping and loudness for all volumes? (System/Notifications/Alarms/InCall/Bluetooth/Earphone/etc)
