The Grundig GDM 202 may have originally been a general-purpose utility microphone, but proves itself as a studio-level secret weapon, especially on electric guitar amps and cabs. With its compact format, solid build, and aggressive tonal shaping, it has found a second life as a world-class instrument mic. This unit has been professionally modified to XLR and mounts via its original boom-threading socket.

the Grundig GDM 202 Stereo Pair transforms a compact utility design into a surprisingly powerful and flexible studio tool. Originally intended for tape recorder use, this matched stereo configuration takes things much further: two perfectly aligned dynamic capsules, mechanical angle presets, and multiple routing options make it a genuinely creative recording device. Whether used as a tight stereo pair, spaced apart, or individually on separate sources, this system delivers a bold, characterful sound with excellent coherence and flexibility.


OPTICAL CONDITION
Good vintage condition. Both microphones and the stereo mounting have small signs of wear and age. Original packaging, plastics, and components are included and in very well-kept condition.


TECHNICAL CONDITION
Professionally converted to balanced XLR. Both capsules are fully tested — they sound identical, with strong output and excellent tonal consistency. The stereo system functions perfectly, including all mechanical angle positions and mounting options.


THIS ITEM INCLUDES

  • Matched stereo pair of Grundig GDM 202 microphones
  • Original stereo mounting system with angle adjustment
  • Original packaging and internal plastics
  • XLR outputs (stereo + individual options)


BUILD & DESIGN

Compact, rugged metal bodies with a distinctive white cream finish and rear cable exit. Each microphone includes its own integrated boom thread, and the stereo mount itself can also be boom-mounted — allowing flexible positioning both as a pair or individually. Originally fitted with a proprietary connector, this system has been professionally upgraded to balanced XLR for seamless studio integration.

  • Capsule
    mid size dynamic capsule with rear vents. Each unit features a dynamic capsule (cardioid, ), carefully matched in this stereo configuration. The identical serial numbering confirms factory pairing, ensuring both capsules share extremely close tonal and phase characteristics — a key advantage for stereo recording.
  • Stereo System & Mechanics
    The included stereo mount is where this system truly stands out. It offers precise mechanical click positions for capsule alignment:
  • 0° (parallel / forward-facing)
  • 90° (classic stereo angle)
  • 135° (wide stereo image with controlled phase spread)
  • 180° (opposed / ambient capture)
  • However the capsules can easily also sit at any angle between.

These fixed positions ensure perfect repeatability and phase coherence, something rarely achieved with improvised stereo setups. The 135° setting is particularly special — it sits between traditional XY and wider spaced techniques, offering a natural stereo field with depth while maintaining strong mono compatibility.


TECHNICAL SPECIFICATIONS

  • Type: Dynamic
  • Polar Pattern: Cardioid (estimated)
  • Frequency Response: Estimated 80 Hz – 13,000 Hz
  • Sensitivity / Impedance: Not officially specified
  • Output: Balanced (XLR, modified)


SOUND CHARACTERISTICS

This stereo pair delivers a striking combination of punch, clarity, and vintage character. Both capsules exhibit:

  • Tight, controlled low end
  • Forward, expressive midrange
  • Crisp, detailed high frequencies without harshness

Because the capsules are matched, stereo recordings feel focused and stable, with excellent center imaging and minimal phase smear.

In use, this system can shift between roles effortlessly:

  • As a tight XY-style pair, it captures coherent stereo images with strong mono compatibility
  • At 135°, it opens up into a wider, more immersive field while retaining clarity
  • At 180°, it becomes a more ambient, room-capturing setup

Examples of use:

  • Drum overheads (tight or wide stereo)
  • Guitar cabinets (stereo depth or dual-mic blending)
  • Piano recording (compact stereo capture)
  • Room or ambient miking
  • Creative reamping and spatial effects


FREQUENCY RESPONSE

Estimated Frequency Response:
80 Hz – 13,000 Hz

  • Controlled low-end roll-off below ~100 Hz
  • Strong presence region around 3–5 kHz
  • Smooth high-frequency extension with gentle roll-off above ~10–12 kHz

A beautifully engineered and surprisingly versatile stereo system — compact in size, but capable of delivering professional, phase-coherent stereo recordings with real character and flexibility.
