The "25th Anniversary" is a hand-wired amp featuring high-quality Cinemag transformers. It’s based on Eric Johnson’s 1968 Marshall Plexi, internally bridged for cascaded gain between the treble and bass gain controls. This particular amp includes factory HX/DA mods, with three switches on the back that let you fine-tune the character and drive. Fortunately, it also features a variable wattage control, acting like a master volume for the output.
This amp in excellent condition, with minimal signs of previous wear.
