INPUT JACKS - LOW AND HIGH

Connect the output of your guitar to one of the 1/4”input jacks with a shielded guitar cable. Select
LOW for normal, or HIGH for extra gain. Plugging into the LOW input will attenuate your guitar’s
signal cooling down a “hot” guitar. These two jacks provide slightly different input levels. Experi­ment with these and adjust to your tastes.
