Tonedevil Guitars offers a deluxe high gloss, grain-filled finish (left) as an upgrade to any of the instrument models.
The S-12 harp guitar comes with a water-based satin polyurethane finish (right). It is sprayed directly onto the instrument and built up with 3 – 4 thin coats. It is more durable than lacquer, but also flexible to prevent cold-checking (the spiderweb-like micro-fissures that result from exposure to dramatic temperature and humidity changes). It is not grain-filled so it allows the wood to resonate naturally, offering a more pure, warm, and fundamental tone.
