Rectofire offers a powerful amp simulation inspired by the iconic 90's MESA/Boogie Dual Rectifier Blackface, rev G, featuring an optional 1 Meg gain pot modification for enhanced tonal control. This plugin is part of the Mercuriall Ampbox platform and includes Ampbox for free with purchase. It provides a comprehensive selection of cabinet impulses, including exclusive Max Morton IRs, as well as cabinets based on models from Redwirez, Bogner, MESA/Boogie, and Marshall, each paired with renowned Celestion or vintage speakers. The microphone options add further realism with Shure SM57, Sennheiser MD441, and Royer R121 models.

Users can load their own cabinet and reverb impulses in mono or stereo, with a maximum impulse length of approximately 5.9 seconds at 44.1 kHz, allowing deep customization of the tone. The plugin includes an extensive effects section, featuring graphic and parametric EQs, noise gate, wah based on the Dunlop CryBaby 535Q, multiple overdrive and distortion pedals inspired by iconic models such as the Ibanez TS-808 and Boss Metal Zone MT-2, as well as stereo chorus, delay, and reverb effects. These tools enable shaping the guitar sound across a broad spectrum of styles.

Additional features enhance the workflow and user experience, including a preset system, movable module windows, and interface customization with size selection and OpenGL rendering options. Controls such as output signal modes (normal, dim, mute), reference pitch tuning, and undo/redo functions support detailed adjustments. The plugin supports multiple sample rates from 44.1 kHz to 96 kHz and offers stereo or mono processing with selectable input channels. Rectofire is designed to integrate smoothly with various digital audio workstations, providing high-quality amp simulation and flexible tone-shaping capabilities.
