I have been using American Musical Supplies for years!
I have been using American Musical Supply for quite a number of years. They are excellent, prices are competitive, delivery is prompt, returns are hassle free and contacting customer service has always been a pleasant experience. The interest-free payment plan options have been in force for years, way before other vendors had started to introduce them, and doesn't involve financing by taking out an associated credit card. It allowed me to purchase quality instruments that I would not normally have the budget to pay for in full up front. I also appreciated how you could select the exact individual finish variation & weight of expensive model guitars, through referenced photos posted on the website. My most recent purchase has been of the new generation Boss RC-500 looper. Instead of saving up for it, I can instead use the time to record backing tracks on it while making monthly payments, so I will be all ready for Summer gigging! The one thing which could use improvement is the search function (or is it more the cataloging system?) on the AMS website. Sometimes when looking for a specific item, (with the exception of the popular big name brand, familiar musical items everyone carries), it often falls short in searches, leaving you to look through endless multiple pages of listed items. I'm certain I have on occasion in the past given up looking for a certain musical accessory or part, only to find it instantly on another site. Other than that, AMS is an absolutely excellent place to purchase your musical items.
