Want to give your Mesa Boogie® Dual Rectifier® Head a new look? We're introducing what we like to call our Recti-Plexi Shell. Our shell will retro fit all dual rectifiers! We put a classic twist on the shell by utilizing a tolex covered valence panel in place of the metal plate Mesa Boogie® installs in their factory. We also applied other plexi cosmetics such as gold metal mesh vent in the top, gold piping and a gold end cap handle.
