L12X is an analog simulation inspired by the Marshall® Lead 12™ solid state amplifier of the late ‘80s.



Current version: v1.1.2 (Sep 2020)

The original head was an op-amp based amplifier: instead of using tubes or transistors, the op-amp is able to provide a huge amount of gain with very little or no distortion. However, when the amplified signal reaches the voltage applied to power the op-amp, it gets clipped. Marshall engineers exploited that to provide a great sounding amplifier with very few components.

This little solid state head is able to push cabinets up to 4×12 and can easily sound like a JCM™. We modified the original circuit by adding a Contour knob (to get a more scooped tone) and an additional Boost overdrive stage. We also included an integrated Cab Simulator, loaded with a Marshall cabinet IR featuring Celestion V30 cones.
