015-BAND EQ
Onboard stomp block — recreate the Mark IIC+ signature V-scoop by cutting low-mids and boosting lows/highs
The METAL 2000 model captures the high-gain saturation and tight low-end tracking of the original Mark IIC+ rhythm tracks without needing an external drive pedal. The Les Paul Custom humbuckers supply plenty of output, so keeping the amp mid setting at 3 combined with the onboard 5-BAND EQ block dials in Hetfield's signature mid-scooped attack. Clean interlude: switch to the 60S UK CLN amp model with the CHORUS block engaged. Middle has no knob on the LT25: press the encoder to open the preset, press it again on the amp model, then select MIDDLE on the display and turn the encoder.
