The Boss EH-2 Enhancer is a subtle, dynamic effects pedal designed to add clarity, sparkle, and presence to instruments like guitar and bass by boosting high-frequency harmonics in response to playing dynamics, acting like a frequency-dependent expander or "reverse compressor". It features controls for Mix, Frequency, and Sensitivity, often considered a "nothing pedal" until disengaged revealing the added polish, making it great for studio work or cutting through a mix.
