No vocals, only acoustic guitar and sax?
I'm certainly no expert, but the mics you picked could be a bit harsh for sax, depending on the sound you prefer and your room.
So, which kind of sax are you playing and how (more soft or more hard aggressive bursts)?
How do you like your sax sound, hard and aggressive or soft and mellow?
How is your room sounding? Do you get unwanted reflections when you play a short loud staccato note?
Do you already have some mics?
