"I would just like to take the opportunity to thank you for your quality customer service. Buying things off of the internet is still a little nerve-wracking for me and can seem very impersonal, but you guys have been awesome, I appreciate your quick responses to the emails and the guitar sounds great! I would have no problem in making future purchases through you and would recommend your service to others."

"I ordered drums for my 13-year-old grandaughter for Christmas. They were ordered on December 21st. I thought there was no way she'd get them in time for Christmas and probably not before New Year's Day. To my surprise, she called us on December 23rd and said she'd already received them. Now that is amazing service. The drums are beautiful and she's estatic! We will surely be ordering more musical equipment in this coming year. Another thing. I'd gone to the local music store which carries lots of equipment and they were out of the drums I wanted to purchase. I got online and found and was able to find the drums I wanted and in a color I wanted. Hats off to your good service and good products."
