You might wonder just how insane the Super Duper 2-in-1 sounds with both channels active and cranked up. Zach says, "I can't get my Les Paul to stop feeding back at any audible volume level on my Marshall . . . I'm happy about that." Of course, wide open isn't the only setting on the Super Duper 2-in-1. It gives you a total of four volume levels, ranging, at your choice, anywhere from perfectly clean to ragingly overdriven:

Level 1: Your guitar is true-bypassed with both channels off.

Level 2: Channel 1 engaged.

Level 3: Channel 1 off, Channel 2 engaged.

Level 4: Both channels engaged
