Best customer service Ive ever encountered. My guitar arrived ahead of the date it was supposed to, in flawless condition. Played well right out of the box. I will be buying all of my gear from you, from here on out. You made me feel like I was ordering a custom guitar, just for me. I was treated like a valuable customer.
