🔹 JS – Brit 900 Ultimate and DI v2
Amp+Cab & DI Tone Models based on the Marshall JCM 900 Model 4500 Amplifier
 
The JS Brit 900 Ultimate and DI v2.0 Tone Model Collection is based on an early ’90s Marshall JCM 900 Model 4500 — a 50-watt dual-channel head known for its unmistakable Marshall roar, biting midrange, and responsive dynamics.

A staple of the high-gain rock and early ’90s era, the JCM 900 combines the aggression of the JCM 800 with added versatility, offering everything from bold cleans to saturated overdrive.
 
This all-new and expanded v2.0 collection includes 24 Tone Models captured using the ToneX v2.0 engine, featuring a variety of cabinet pairings and DI captures for maximum tonal flexibility.

Each channel (A and B) was captured at three gain levels through multiple cabs — from modern punch to vintage grit — plus pure DI amp-only versions with a preset-level baked-in IR.
