I havta sell my Epi G-400 n it has a hardshell case. Ive had it on craigslist fr a while n only a few replys but no serious buyers. its in great shape n im asking $200, that to much?
that depends on where you live...
here in utah i hve to sell crap at like 60-70% off for it to sell. It blows man.

Back when I was in california if it was like 30-50 %off retail it was gone in a day.
Have you tried ebay? That's always a good way to sell equipment, there's 1,000s (possibly millions) of people looking on there every day.

Also, I don't know if you can do this on craigslist, but on ebay you can search for 'Completed Listings' so you can tell if you're asking the right price or not.

Try kijiji. I dunno where your at, but kijiji has 900+ guitars here.
Craigslist has less then 20. I buy and sell stuff on kijiji all the time.
Its also set up alot better then craigslist.
ebay is the way to go, never had a problem selling on there
