MRSH JCX 2203 (NAM)

BRITISH CRUNCH. NO MERCY.

The Marshall JCM 800 2203 is one of the most recorded amp heads in history. No channel switching, no effects loop, no frills — just a single channel of cascading British gain that defined the sound of hard rock and heavy metal for an entire decade. This pack captures it across 90 Neural Amp Modeler profiles spanning three gain tiers, both clean and pushed with a boost in front, in DI format and as full-rig profiles with two classic Marshall cabs. Whether you want the amp wide open or tightened up with a boost, it is all here.

The 30 DI profiles cover 15 amp settings across low, mid, and high gain positions, each captured raw and with boost engaged, ready to pair with any impulse response or cab sim. The 60 full-rig profiles take every one of those same settings and marry them to two separately captured Marshall cabs: a 1960A loaded with Greenback speakers for that warm, harmonically rich midrange character, and a 1960sB loaded with Celestion V30s for a tighter and more present edge. The full-rig profiles are completely plug-and-play — no IR loader needed. The pack also includes 56 bonus impulse responses from both cabs, 28 per cab, so you have everything you need to build your own signal chain from the ground up.
