The Effects Loop is tube driven. It is wired in series and there is no need to turn it on or off. The Return jack will activate when you put a cable in it. Hence, when you plug a cable in, it turns on. When you unplug it, it’s off. HERETIC OWNER’S MANUAL PAGE 5 OF 16... - Page 10 It is perfectly normal to run the amp with a short (1’ or 2’) patch cable in the loop at all times. If you like having the master, jump the loop.

When the presence knob is dialed up north of around 4, you’ll really start to hear the change. If you want your tone more aggressive, roll the presence up.

Page 15: Deep Control
Deep control varies the amount of low-end resonance. Turn it all the way off and it takes itself out completely. As you turn it up, up goes the low-end. Pretty simple. SWITCHING Your Heretic provides you a number of ways to switch your amp. Let’s get familiar with all of them! FRONT PANEL SWITCHING Your amp’s front panel comes equipped with 3 small toggle switches. -
