I have sold a few hundred guitars online. 2 things I've learned: 1) the more questions the buyer asks, the less likely they are to be a serious buyer and 2) Give no detail that allows for remorse/partial refunder buyers. They can go somewhere else. IE: It weighs 8 lbs 4oz. Or the neck measures 19mm at the 3rd fret.
The reason is not to be an asshole, its because pieces of shit scrabble together a couple of grand and spend the next year "demoing" guitars looking for the one that will make them the next SRV while sending dozens back in the process and costing me time, trouble, and money. I want to be clear: I no longer sell online due to these headaches and I have never had a customer that thought I was shady etc. Unfortunately, what used to be a fun hobby that alotted me some free gear occasionally is ruined by scumbags. I can tell you stories you wouldn't believe.
