The Mesa Boogie Rectifier is a two-channel, 100-watt amp head, originally released in 1992. It boasts a devastating high-gain tone, seismic bass, and clipped mids that defined the sound of 1990s metal, grunge, and alternative rock.
It features a rectifier type selector (tube or silicon diodes), a series effects loop, a slave output ideal for modelers or impulse responses (IRs), and a bias switch for easily toggling between 6L6 and EL34 tubes.
The Mesa 4FB cabinet is a 240-watt model with four 12-inch Celestion Vintage 30 speakers. The 4FB designation on a Mesa cabinet refers to its factory configuration: four speakers and a full (closed) back panel. It is generally associated with the iconic Rectifier Standard Oversized model, widely considered a standard in the rock and metal industry due to its powerful low-frequency response.
