This is the updated MKII version, originally inspired by George M’s personal favorite 1968 Plexi. The MP-100 MKII serves as a versatile tool for capturing different vintage Marshall tones, offering a range of character options through the cascaded gain controls and a switchable “12301” channel. With plenty of gain on tap, you can easily push beyond the limits of a bridged ’68 Plexi or dial it back for a more classic, subdued sound. This amp appears to be in great condition, showing only minimal signs of previous wear.
