BRITISH CRUNCH. NO MERCY. — NOW WITH A2 PROFILES
180 NAM Profiles (90 A1 + 90 A2) & 56 IRs

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. Version 2 of this pack is a major update: all original 90 A1 profiles are included alongside 90 brand-new A2 profiles captured in the updated Neural Amp Modeler format, bringing improved accuracy, tighter low-end response, and more nuanced dynamic feel to every gain setting in the collection. Whether you want the amp wide open or tightened up with a boost, it is all here — now in twice the resolution.

The 30 DI profiles per format 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 per format 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.
