Note: An effects unit may be inserted between the X-Over Outputs and the Effects Return Jacks. For instance, it is a popular practice to insert a Chorus unit between the Hi X-Over Output and the Left Stereo Effects Return, so that only the high frequencies are chorused while the low frequencies remain tight and dry. In this manner, the player can get the desired special effect without “muddying up” his/her tone.
