The Tegeler Audio Classic Equalizer is a high-end passive tube equalizer built to deliver the unmistakable warmth and musicality of classic vintage EQ circuits. Its passive boost-and-cut topology allows for broad, natural shaping of low end, silky enhancement of the highs, and subtle smoothing of harsh frequencies. Adjustable treble bandwidth and transformer-balanced tube stages introduce gentle harmonic richness without overwhelming the source. Designed for tracking, mix-bus work, and mastering, the Classic Equalizer adds depth, weight, and openness while maintaining a clean, natural character. It's ideal for engineers seeking timeless analog tone with precise yet musical control.
