This is a Yamaha SLG200N Silent Guitar (or the wide-neck SLG200NW variant), a nylon-string acoustic-electric designed specifically for travel and silent practice. It appears to be finished in Tobacco Brown Sunburst.
Detachable Frame: The most striking feature of the Silent Guitar is its minimalist body. The upper bout of the rosewood and maple frame completely detaches from the center block. This allows the entire instrument to break down and fit into a highly compact gig bag, making it an ultimate travel companion.
"Silent" Design: Because it lacks a traditional resonant acoustic chamber, it produces virtually no acoustic volume in the room. This makes it perfect for late-night practicing without disturbing others.
The Neck: It is set up like a classical guitar with nylon strings and a slotted headstock. The standard SLG200N features a slightly narrower nut for crossover players, while the SLG200NW features a traditional, wide classical neck.
SRT Powered System: The control panel on the back houses Yamaha's proprietary SRT (Studio Response Technology) Powered preamp system.
Controls: It allows you to blend the dry piezo pickup signal with a digitally modeled acoustic microphone sound. It also features built-in effects (like reverb and chorus), a built-in tuner, and a direct headphone jack for fully immersive, silent practice.
Because these are highly practical instruments for both traveling musicians and apartment players, they hold their value quite well.
Retail Value: Brand new, the SLG200N retails for around $880, while the wide-neck SLG200NW retails for roughly $980.
Used Value: On the used market, assuming the electronics work perfectly and the original gig bag is included, they typically sell for between $450 and $650 depending on the specific model and condition.
