Solidus VS8100

Analog Modeled Solid State Amplifier Plugin


Add to cart


Solidus VS8100 is an analog simulation of the iconic Marshall® Valvestate™ 8100, solid state amplifier from 1991.

The original head was the first incarnation of the Valvestate™ series, a solid state amplifier with a 12AX7 tube as a driver for the distorted channel tone stack, which defined the history of death metal through the 90s. It featured two channels: a Normal channel, for clean guitars, and a Boost channel for distortions.

We carefully modeled the original amplifier and added some goodies to further shape your guitar tone: a noise gate, a modern overdrive, a EQ/Booster (to make your own custom clean booster), a post-amp 5 band EQ and a Cab Loader.
