The Smooth P90 is great for blues and jazz tones and clean chords AlNiCo 2 Magnets. Porter used a winding pattern with these p90s to help bring out the tight notes and big sound. Standard output winding results in 7k range for the neck and 8k range for the bridge. Braided hookup wire and wax potted to prevent excess microphonic feedback.
Pairs nicely with a classic in the bridge or another smooth in the bridge.
