Myburgh M28 Large-Diaphragm Multipattern FET Condenser Microphone

The Myburgh M28 is a hand-built, large-diaphragm multipattern FET condenser microphone designed by Drew Myburgh, Eckehard Dux, and Andreas Grosser. It pairs a German-made CK12 capsule with an original FET circuit and a custom Pikatron transformer, an approach designed to respond to a performance the way a tube circuit does. Five polar patterns on a stepped switch, a 0 dB / -6 dB pad, and a 134 dB maximum SPL make it adaptable across a wide range of sources. It runs on 48V phantom power alone, with no external power supply, tube, or warm-up time.

Key Features

• German-made CK12 capsule, the capsule construction behind the top-end air and clarity associated with the C12 and ELA M 251
• Original, proprietary tube-like FET circuit, designed as a new circuit rather than a recreation of a vintage schematic
• Custom-specification Pikatron transformer that works with the circuit to add subtle second-order harmonics
• Stays clean at low levels and moves toward a warmer character as a performance pushes
• Extended frequency range of 30 Hz to 20 kHz (±1 dB) for a direct view of the CK12 capsule
• Five polar patterns on a stepped switch: figure-8, hypercardioid, cardioid, wide cardioid, and omni
• 0 dB / -6 dB pad on a stepped switch, with 134 dB maximum SPL (no pad)
• Runs on 48V phantom power alone (approx. 3.2 mA, within the P48 standard), with no external supply, tube, or warm-up
• Low current draw by design, based on repair-bench experience that underpowered preamp phantom supplies are a common cause of FET microphone faults
• Hand-built in Germany, with every circuit and mechanical component designed and manufactured in-house
• Stepped miniature switches for pattern and pad, chosen for durability after a long search for a reliable mechanism
• Suited to vocals, acoustic guitar, upright bass, piano, and close drum ambience (placed roughly half a meter either side)
• Includes a 7 m (23 ft) cable, custom cover, waterproof case, and swivel pouch
• Two-year warranty on the capsule and five years on all other parts and workmanship
