Rock Amp Legends by Jimmy Crespo is a guitar amp simulator developed through a collaboration between Nomad Factory and renowned guitarist Jimmy Crespo. Designed to deliver authentic rock tones, this plug-in captures the essence of classic British and American amplifiers through impulse response technology. It offers a comprehensive set of effects and tonal shaping tools that allow guitarists to craft signature sounds with ease.

The simulator features input stages with adjustable levels and tube emulation that bring warmth and character to the sound. Adding depth and movement, integrated effects such as tremolo, auto-pan, chorus, phaser, delay, and reverb provide a rich sonic palette. Additionally, the plug-in includes a compressor and noise gate to refine dynamics and reduce unwanted noise, ensuring clean and punchy guitar tracks.

To fine-tune the tone, users can access a parametric equalizer alongside presence, treble, middle, and bass controls, as well as an overdrive drive section for added grit. The interface supports standard sample rates and is optimized for low CPU usage, making it suitable for various recording setups. Licensing options include disk authorization and iLok support, allowing flexible integration into professional workflows.
