2108 was to capture the original character of the 1108 and to create a solid state mic pre reminiscent of that era. Like all of the great vintage gear of that time, the 2108 is an all discrete class A unit with input and output transformers. In addition to the output stage used in the 1176, the 2108 features our best custom input transformer (featuring multiple impedance windings) and a new FET front end with incredible sonic dynamics. -
