"Genuinely the nicest experience shopping here. The staff were so friendly and spent a good deal of time (unhurried time!) helping me and explaining everything to me so I could choose the right items for my setup. If there were more than 5 stars to give they would get them all."

"The highly professional and helpful staff here are just outstanding. As a music teacher myself, I know I can always find great advice and high quality products. This is my one-stop-shop for all things music on the Central Coast."

"Came through looking for a guitar. Chris was run off his feet serving multiple customers but still kept checking in with me and pulling guitars down left right and centre for me to get a feel for. His expertise made the whole process comfortable and I was able to return later that same day and buy the guitar Chris helped me select. Great service and will definitely be back."
