Surprisingly Rhythmbox does not include an equalizer by default. Here are the directions for installing a 10 band equalizer plugin for Rhythmbox. It works in Linux Mint 13 and Ubuntu 12.04.
First you need to add the PPA. Open Terminal and type:
sudo add-apt-repository ppa:fossfreedom/rhythmbox-plugins
Enter password. After it is done, type:
sudo apt-get update
Then to install the plugin, type:
sudo apt-get install rhythmbox-plugin-equalizer
Start Rhythmbox, enable the Equalizer plugin.
Start the Equalizer from the Control main-menu
