2013 GIBSON SONGWRITER DELUXE STUDIO with Free Tronical Tuner: The reason I'm selling this great sounding guitar is because I've upgraded and I don't need 2 acoustics. This guitar is great to play and the action is great being just set up by Strange Guitars in New Orleans, you can see the string specs in the pics. The tronical tuner is awesome if you like playing in alternate tuning regularly. You won't take more than 10 seconds to switch between any programed alternate tuning and standard. You can do it by strumming all the strings or just one at a time. Just making sure you're in tune is just that easy too. I'll send also the original tuning keys with the guitar. I'm very motivated to sell it being that I've just purchased this is my bottom dollar price. If you do the research on the cost of everything you'll find I'm loosing a little money here. I know that this upgrade is rare but trust me its so worth it!  01. What is TronicalTune about? The world´s first real retrofits autonomous auto tune system located at the guitar's headstock. It auto tunes your guitar in seconds! 02. How does TronicalTune work? TronicalTune measures your guitar´s natural born sound frequencies at the headstock. An intelligent learning algorithm captures and stores the acoustic properties in relation to the frequency mixture of your guitar. It then creates all needed motor commands so the servos auto tune your guitar in seconds. The exchangeable, rechargeable battery pack is good for up to 300 tunings!
