Ranger is a very simple effect that allows you to remove wanted frequencies and saturate the resulting signal.
It features one low cut filter and one high cut filter, both up to 30 dB per octave and with a bypass switch. There's also a master bypass switch and input and output level meters.
This effect has full automation.
This is a free plugin but, to download, you must be a fan of the Ourafilmes Facebook page as it is included in the Ourafilmes Facebook Free Pack.
