I have been buying from Sweetwater close to ten years now. I have had the same service engineer Matt Kreager who has gotten to know what I expect. I can honestly say that I have been 100% satisfied with all of my purchases as well as all my returns. Quality control can be a big issue with all companies. Because I by from Sweetwater I have not had to settle for anything less than perfect. I have always been satisfied with the equipment that I have purchased is the best it can possibly be. When it wasn't Sweetwater took care of that for me.
