Input Stage Requirements
First Enabled
Input Z (Impedance)
+2.0 dB
Gain Stage Offset
Maintains natural P90 high-end articulation and reaction to drive blocks. Gain staging offset is compensation relative to the humbucker baseline.
Preset EQ Frequency Cuts
90 Hz
Low-Cut Target
8.0 kHz
High-Cut Target
Cab or IR block roll-off targets. Roll-off preserves the growling low-mids and tames high-frequency P90 noise and single-coil sizzle.
