what i can say about sweetwater is they are the best in online buying,yes if for any reason at all they will take it back,you have 30 days to return it for a full refund.what i like about buying from SW is they really do get to know who you are,i spent countless hours on the phone with the rep,just talking about gear playin guitar ect.when you call and make your first purchase thats the guy u will get all the time.and thats worth allot,he knows what you have ,and dont have,he will neverchase u off the phone after a purchase,and they are all very knowledgeable.the down side off SW they dont macth prices....oh and if ur buying a guitar,they do a 55 point inspection on it,so its ready too hit the stage straight out the box.i like MF cause i get much better deals,no phone support just better prices.
