I saw this amp on Guitar Center’s used listing for a good price, and pulled the trigger. The store actually notified me that it was a return due to some damage, and waited for my confirmation before shipping it out - very much appreciated and I hope that continues in the future. GC has notoriously sent me some very damaged/broken equipment so this is a big step in the right direction.
Anyway, I got some photos from the store and decided to go ahead with the purchase. Upon arrival, the amp is in very good condition and the only damage is the plastic power socket was punched through into the chassis - if I had to guess, it was shipped with the power cable plugged in and it hit against the inside of the box, pushing it in. This did damage the socket itself, but a replacement plastic socket is only $3 online, and better yet it’s simply spade terminals, no soldering required - but of course, have to be very careful due to the high voltages. I’ve already ordered the replacement part.
Otherwise, it sounds and works great so far. I have some thoughts on the tone which I’ve posted on the amp’s page here: 2015 Mesa Triple Rectifier Multiwatt
My only complaint really is that the footswitch is missing, and Mesa charges $165 for a replacement, plus another $36 for the cable ($201 total for the footswitch system). You can manually change channels from the rear panel, but one of the highlights of getting a versatile 3 channel amp like this is being able to change channels easily! I’ll see if I can find a used footswitch somewhere, somebody has to have one.
