They each play and sound very different. The 1958 330F has a wider neck. The back of the neck is kind of flat and really feels good in your hand. I've got a variac on the way for my old Vox. I blew one of the original speakers since the voltage coming out of the wall was 125-132 and it cooked it. Variacs allow you to warm up the tubes and regulate the voltage to 110 which is what used to come from outlets. Seems like I learn everything the hard way. I'm sure I'm by myself on that one. I might post some of the sounds of each on youtube one day.

I was checking that out. I really think his is a '59 model. Maybe Chris can check the pot dates. A '58 would most likely have a long slash soundhole and bridge with no cover. Whether its a '58 or a '59 .......its gorgeous!
