A friend of mine is going to let me record my classical guitar in a special place at his house. He created a CMU masonry block castle 40’ tall. The castle at the bottom is 8’ diameter. He cut a door into the bottom and you can go into the belly of the castle. On the inside the castle belly is like a rounded ball with a hole in the top with a 3’ wide round opening going up to the top of the castle. My classical guitar when played in this chamber has the most unbelievable natural reverb and tone I have ever heard. I have an opportunity to record in this chamber the weekend after Thanksgiving. I have 2 recording guys that offer me 2 ways to record: 1. The first wants to used digital recording. He has some $1,500 German mic to put at the top of the chamber and a directional mic for being in front of me. 2. The second wants to use a Tascam tape recorder and has some Sure mics. If we use tape I will go to digital eventually as their will be editing involved no doubt. Based on this scenario, what is recommended to get the best recording of my guitar?
