I think you're being hard on yourself but if I felt that way, I'd probably take a break. However, if your genuine intent is to help, you don't have to answer to anyone.
(Just keep doing what you do)
Yeah, it's a shame things seem to have got a bit heated here on S-T, and I don't know why. Between us, I think we've flagged up to the OP that this guitar isn't quite what it seems, so potentially saved him/her from buying an instrument that is probably best avoided. We should be proud of that.
Maybe it would help if we could all be a little more respectful of others insights and opinions? None of us can ever know everything, so rather than posting: "You're wrong because", we should perhaps be saying: "My personal opinion is...".
The written word is one of the foundations of civilisation. It's also a terrible medium for conveying expression in terms of whether you are joking, just being a bit disrespectful for fun, outright angry etc etc. So, no need for any of us to get in a fight and no need for anyone to leave over a disagreement regarding a guitar we'll probably never see again.
