I've ordered twice from Sweetwater (PA gear, electronics, and accessories - never a guitar) and they were both positive consumer experiences. Easy to work with, prompt shipment, correct contents.
The only negative thing I have to say is their "follow-up" policy. Seems that the sales staff have strict orders to follow up several times with phone calls to see if you are happy with the purchase. If I were not happy, they would certainly know promptly. While post-sale follow-up is not necessarily a bad thing, they kept calling my work cell phone early in the morning (I am in a different time zone) waking me up and using up my cell minutes. Despite repeated requests to stop they kept on calling, so I eventually was forced to block their number. After a dozen or so unanswered calls over the next three months, they finally gave up. So instead of a warm fuzzy feeling of support I was left with a sense of harassment, and have not ordered from them since. Just be careful what phone number you give them when ordering. I wish I had given them the fax number.
