Why these settings

The Zoom G1X Four's BG LEAD amp block accurately captures the Mark IIC+ lead voicing; pairing it with the TS Drive block as a pre-gain booster tightens attack and gives Kirk's searing lead sustain. The Sqoe Seib 500's passive bridge humbucker has plenty of bite, so mids are kept slightly higher (6 on amp, subtle post-EQ scoop) to maintain vocal cut rather than rhythm scooping. Keep the onboard reverb dry as the album solo relies purely on tight room acoustics and fast wah articulation.

PRO TIPKirk keeps his TS9 level high with gain near zero to push the Mesa's front end into singing saturation; rock the expression pedal forward sharply on sustained bends to trigger that iconic vocal upper-harmonic squeal.
