Pulp Logic Primitive

The Pulp Logic Primitive delivers old-school analog ring modulation and waveshaping to any Eurorack modular synthesizer system it is a part of. The module utilizes transformers and uranium diodes for the multiplication of input signals, resulting in an output that includes both the sum and difference of the input frequencies. This results in a distinctly metallic sound that has been used to great effect throughout the past few decades.
