Why these settings

The Mustang LT25 lacks the JCM800's natural mid-forward bark, so mid is pushed to 7 (vs King's flat 4-6 on the Marshall) to compensate for Fender voicing's inherent scoop. Bass is dropped to 5 from the original's 6-7 because the Metal 2000 model gets flubby in the lows. Gain stays at 7—your Ibanez's ceramic humbuckers are hotter than vintage DiMarzios, so pushing higher causes mud.

PRO TIPKerry King's secret is mids, not gain. If your tone sounds thin or buried, raise mid before touching gain. Pick directly over the bridge pickup pole pieces with a stiff 1.0mm+ pick angled sharply for that percussive thrash attack on the intro riff.
