So Last week i was online looking for used mesa 810 cabs and came across one for sale at the Warwick, RI Guitar Center. It was an old Road Ready 810. Looked to be in decent condition. It was priced at around $750, so i got really excited. Called the store the next day and asked someone about it. They said it sounded huge and that the only thing that was "wrong" with it was that the previous owners had spray painted their band name on the front lid. I asked if they could send me more pics and they were glad to. Once again, all looked well and good. I called several more times over the next two days, talking to a few different managers trying to figure out how to get the thing to minneapolis, mn where im located. it was a little more complicated since i needed the thing to be shipped to the guitar center here instead of my house because im rarely home. Finally got everything squared away, paid a total of $909 after shipping and tax. I made sure to ask again before i paid for it if there was anything structurally/cosmetically/functionally wrong with the cab. They assured me that it was all good. Four days later the cab is delivered to a local gc, and i rush over after work to pick the thing up. they wheeled it out of the back, we unwrapped it, and pulled the front lid off. I immediately noticed that the top two speakers had very large, visible tears in the dust covers. I figured if those speakers were in that bad of shape, there had to be some kind of damage to the rest of them. I gave them a quick test with a 9 volt battery, they all jumped together, which gave me a little glimmer of hope that it would still sound alright. We wheeled it over to the bass section and plugged it in to a mesa carbine head they had there and it was probably one of the most disgusting sounds ive ever heard come out of a cab in my life. turns out there was another driver near the bottom that had another large hole in the dust cover, and a tear in the cone, which produced a huge farting noise with every note. i also noticed that the speakers were moving and jumping a lot more than they seemed like they should be. i took a quick look around the back of the cab and noticed that the metal edge on the rear right side that is supposed to hold the thing together was separated from the cab, and the back panel and side panel were no longer connected and a LOT of air was being pushed out the back side. the dudes at my local gc were very helpful in getting my money back right away, and were almost as angry at the other store as i was since they are now stuck with a broken speaker cabinet and have to try to sell it. long story short, the staff at the guitar center in Warwick, RI are liars. Flat out liars. dont buy any used gear from them unless you can physically go to the store and see it for yourself. this will be the last time i buy anything from a guitar center. ive had bad experiences there before, but this one takes the cake.
I suppose it's possible that the cab could break from a jolt and not damage the outer packaging but it doesn't seem likely.
