I absolutely LOATHE (is that spelled right) UPS for shipping amps!! They do OK on small things that aren't breakable, but not amps.
1) Bought a Triple Recto off ebay and they shipped it UPS - When I got it, it had 13 broken tubes!!
2) A friend shipped off his Line 6 Spider amp in the same Line 6 box (and packaging) he got it from a few years ago off of Musicians Friend.com.... A few days later he gets a call from the local UPS store and they said "you better come down here". His Line 6 amp is in 6 peices inside the box!! All the joints broke and every screw that held the chassis to the cabinet were broke.
3) Rectoverb Combo can to me with a 2 broken power tubes and a whole in the box all the way through the grill and the speaker where something had "stabbed" the box in shipping.
Those are my 3 horror stories of UPS. I now use or request DHL or Fed Ex. I just shipped my Road King combo off via DHL and it cost me $175 to ship, but it got to the destination in the same great shape I shipped it in.[/quot
I would take it to a professional packer . Mesa sends all their amps by UPS . At least thats how they arrive here in SC . I suppose Im lucky . never had a problem with them .
