I joined this forum just to respond to this thread. I placed an order on August 31st with The Guitar Files. After two weeks and no guitar, and no responses to my E-Mails, I was forced to file a PayPal claim. Scarily enough, in the middle of the claim PayPal went straight to the escalation phase. That leads me to believe that there is a definite problem with the company, as I would prefer to have the guitar I ordered. The only E-Mail I ever got from them was the auto response from PayPal, I didn't even get an order confirmation from them.
There's no chance of any updates/E-Mails going into a Spam folder, as I don't have one. I own the domain, and even if there was a "typo" in the user name field, I'd still get any E-Mails that they would send. I figured that there might be a delay in shipping because they're in Delaware and could have gotten hit by Irene, but after two weeks and no E-Mails or phone calls, it was time to give up. I found this thread while searching for them, I wish I had found it before I placed my order.
I know that things come up, as I own a small business myself, but I let people know right away if there's any issues with things taking longer than my stated wait times.
As for any claims of me joining just to badmouth them - my user name is my company name, and I post under the name dominus on KVR and Seymour Duncan's forum. (dominus was already taken here.)
