Bass and treble controls on master output

Boost and cut your master signal’s bass and treble levels to better contour your signal to your settings. If your overall signal is a little tinny, cut your signals treble a little; for overly mushy signals – try to increase it. If you need more low-end, boost your bass control; or cut it to help reduce punchy audio.
