Why these settings

The Katana 50 MkII Lead voice provides the hot-rodded Marshall JCM800 bite Vivian Campbell achieved with a cranked 2203 and Boss overdrive. Mids are pushed to 7 to deliver the aggressive British midrange cut, while bass is kept at 5 to prevent low-end mud on the 1x12 combo. Presence is physically absent on the Katana 50 faceplate and set to null.

PRO TIPDig in hard with a heavy pick angled slightly toward the bridge to emphasize the sharp pick attack and harmonic squeals characteristic of Campbell's riffing.
