Hello, I have a 2 channel H that has a date of 12/11 on the back of it and I was wondering how I can tell what revision it is? I can't really find any thing else outside of that date and the serial number that would indicate what it is.

Also, depending on the revision it may be, would it be a wiser investment to have PRS upgrade it to the latest revision or upgrade to the new Custom H? Do the updates that you can get bring it closer in line with the features of the new H? Anyone know the list of updates/addons that are available?

Thanks in advance!
