Frequently Asked Questions

While the presets are modeled after the Fairchild, the LCA 2B maintains its own distinct clarity and transparency, lacking the extreme saturation of a vintage Fairchild.

It requires some practice and experimentation to master the variable controls, but the ability to finely tailor the response is what makes it so powerful – a learning curve worth the investment.
