🎛 The Art of Analog Sound: Six Boutique Masterpieces from KERWAX & MELODIUM 🎙
When it comes to capturing and shaping sound with depth, warmth, and authenticity, few names resonate like KERWAX and MELODIUM. Hand-crafted in France with uncompromising attention to detail, these six products represent the pinnacle of boutique analog design – delivering sonic character, musicality, and precision to recording engineers and producers worldwide.
KERWAX REPLICA RevC – Tube Line Preamplifier with M/S Mode
The KERWAX REPLICA RevC is a 2-channel tube line preamplifier inspired by vintage consoles, updated for modern workflows. Designed to add harmonic richness, warmth, and subtle drive, it features dual audio modes (Left/Right and Mid/Side), allowing engineers to process stereo signals with unmatched flexibility. Whether used for mixing, mastering, or sound design, the REPLICA RevC excels at adding analog depth and shaping transients with tube coloration.

Features include dual tubes per channel, tube bias adjustment, gain and volume controls for harmonic distortion, EQ adjustments, selectable high-pass filter, individual phase switches, and VU meters for output monitoring. This is a powerhouse tool for adding presence and dimension to mixes.
KERWAX K-23R – Ribbon Microphone
The KERWAX K-23R is a classic ribbon microphone that delivers a warm, natural, and detailed tone with low distortion and excellent transient response. Ideal for drum overheads, electric guitar cabs, brass, horns, or room mic applications, it excels in capturing sources with smoothness and character.

Hand-built with a 2.5-micron aluminum ribbon and custom transformer, the K-23R offers a bi-directional Figure-8 pattern, extended low-end response, and high SPL handling. Finished in stainless steel, its design combines durability with refined sonics. A reminder: ribbon mics require care—never apply phantom power and avoid blowing into the ribbon.
