This is the Rectifier! Our version of the Mesa Boogie Dual Rectifier in a small box. We replaced the preamp valves on channel 3 of the Dual Rectifier with JFET transistors. The tone stack on our version is passive, just like the valve version, and operates in the same frequency ranges. It also has a presence control to make it even easier to adjust the pedal's tone, increasing or decreasing the treble/mid-treble region of the sound.
All JFETs are calibrated individually, in order to ensure greater precision and standardization of the circuit. With 4 gain stages, the Rectifier covers a wide range of tones, from classic metal to modern metal, such as the sounds of bands like Metallica, Korn, Dream Theater, etc.
