JS Plex King Green Ultimate + DI Capture Collection (Quad Cortex v2)
THAT British Sound. Captured Right.
 
The JS Plex King Green Ultimate + DI Capture Collection is based on the Tone King Royalist Mk. III amplifier, delivering a full range of classic British-inspired tones—from articulate cleans to rich, harmonically complex overdrive.
 
This collection was captured through a 1x12 cabinet loaded with a Celestion Heritage G12M Greenback 20-watt speaker, providing a warm, woody midrange, smooth top end, and the unmistakable character of vintage British breakup.
 
At the core of this collection are three distinct voicings, each representing a different era of iconic British tone:
1964 (64) – JTM 45 inspired tone
1967 (67) – Iconic “Plexi” inspired tone
1970 (70) – “Super Lead” inspired tone
 
Each voicing is captured across six volume settings (4, 5, 6, 7, 8, 10), delivering a natural progression in gain, compression, and harmonic response—from clean and dynamic to fully driven tones.
