Suzuki SMD-138 Uni-Directional Dynamic Microphone

The Suzuki SMD-138 is a professional-grade uni-directional dynamic microphone, characterized by its sleek, all-black matte finish and heavy-duty metal construction. This specific model features a standard handheld tapered body with a series of horizontal recessed rings integrated into the upper neck for improved grip. The head of the microphone is protected by a spherical, black-coated steel wire mesh grille which includes an internal foam pop filter to reduce plosives. A prominent white block-letter 'SUZUKI' logo is printed on the collar alongside the 'UNI-DIRECTIONAL' designation. The body is equipped with a sliding on/off power switch recessed into an oval-shaped plastic housing, featuring a red indicator dot to signal when the device is active. The microphone is attached to a thick, flexible black rubber-jacketed audio cable, suggesting a hard-wired configuration or a standard XLR-to-1/4 inch connection common in late 20th-century audio equipment. In terms of condition, the item appears to be in excellent used state with minimal surface scuffs. The grille remains perfectly spherical without denting, and the finish shows little to no significant wear or oily patina from frequent handling, indicating well-maintained condition. This model is typical of late 1980s or 1990s Japanese manufacturing, known for durability and reliable performance in vocal reinforcement and karaoke environments.

Based on my examination of the Suzuki SMD-138 Uni-Directional Dynamic Microphone, I find the item to be in 'Excellent' cosmetic condition. The matte finish remains intact without the common ‘buffing’ or shine associated with heavy use, and the spherical steel wire mesh grille shows no signs of impact or denting. Authenticity appears consistent with late 20th-century Japanese prosumer audio production, specifically the robust karaoke and entry-level public address markets of the 1990s. Market demand for this specific Suzuki model is relatively niche. While durable and reliable, it lacks the 'cult' status of professional staples like the Shure SM58. Comparables often consist of contemporary offerings from brands like Teisco or Pioneer, which generally trade in the $20 to $50 range depending on the inclusion of original packaging. Its primary value lies in its 'New Old Stock' appearance and its utility for vintage audio enthusiasts or enthusiasts of Japanese electronics. Several factors limit this appraisal. As this is a dynamic microphone, the internal diaphragm and copper voice coil are sensitive to moisture and mechanical shock that may not be visible. I cannot verify frequency response, presence of signal noise, or the integrity of the soldered connections within the recessed switch housing from images alone. A full physical inspection would require a continuity test with a multimeter and a sound-profile test through an amplifier to confirm the output gain is within factory specifications. For definitive authentication of its internal components, I would need to remove the grille and transformer housing to verify the manufacturer’s stamps on the capsule assembly.
