Why these settings

Your Fender CD-60S is an acoustic guitar—this is a significant mismatch for Hetfield's high-gain metal tone. Acoustic piezo pickups lack the output, compression, and frequency response of EMG 81 humbuckers. The Valvestate VS30R's OD2 channel can produce usable gain, but you will get a thin, harsh, undefined sound without an electric guitar. Mid is scooped hard (2) to approximate the Mark IIC+ character, bass pushed to 7 to compensate for acoustic's lack of low-end thump, treble at 7 for cut. A distortion pedal is strongly recommended to add focus and saturation the amp alone cannot provide.

PRO TIPThis tone is fundamentally unobtainable on an acoustic guitar. If you must try, use aggressive downpicking directly over the soundhole and consider plugging into the amp via a soundhole pickup if you have one—but the honest answer is you need an electric guitar with humbuckers to get anywhere close to this sound.
