A huge part of what makes Faders, Faders.. is our music school. We have 12 instructors on staff that teach all ages and skill levels in guitar, piano, drums and voice. Over the years we have taught hundreds & hundreds of students the joy of learning a musical instrument. Some of our former students have even become teachers at the store!

A few years back we thought it would be cool to add new and used vinyl records to the store. It's been a huge hit! We also recently started bringing in rock band T-Shirts & other "lifestyle" type stuff.
Our goal has always been to be a comfortable place for music lovers to hangout, shop and/or learn how to play.
