Level capture

Hello, when you’re recording, you need to make sure the gain stays green, but what output level are you setting: -12dB, 0dB, or something else? I’ve tried at least five times, and the result isn’t satisfactory. Here’s the configuration of the pedal I’m trying to record: IR off, compressor off, noise off, EQ flat, drive 30%, character 80%, blend 50%. It’s an Adam.
