Reverb.com is a fairly new entry in the guitar marketplace. It’s a competitor to eBay that is focused solely on musical instruments. The site is founded by the owner of Chicago Music Exchange, so there’s a history of running a guitar retail shop behind the site.
I recently purchased a Gibson SG ’61 Reissue from the site, and I was pleased with the experience. Communication with the seller was easy, and, like eBay, there’s a feedback system that you can use to verify a seller’s track record. The guitar arrived safe and sound, and I was able to leave positive feedback easily for the seller (and he for me).
My only complaint is that they seem to be fairly aggressive in marketing the site. A few months ago, they contacted me through a Craigslist ad in an effort to get me to post the item on Reverb. Not a huge issue, but I thought it was a little spammy.
That issue aside, I’ll definitely use Reverb.com again in the future when I purchase any new guitars.
