Thanks for the info Joker. :^>)
Now, a bit of Devil's Advocate here. Why would a transferable warranty matter so much to a new amp buyer? If the warranty is only good for a couple of years, are you buying it planning on getting rid of it soon and would the ability to transfer help you make the sale? Does it matter to a used amp buyer? In my experience, no.
And when you really get into many "Limited Lifetime" warranties, what's actually covered? More folks should read those, you're likely to be quite surprised.
As to why "little amps" are often covered, the answer is simple, they're much less expensive to fix and, as one well-known manufacturer is said to do, simply tosses them in the trash and sends you a new one. With the continued growth of Chinese product, IMHO, you'll begin to see more and more disposable gear. "Don't bother sending it back, just toss it and we'll replace it".
You also hit one very important point. How many of you have your original sales receipt? How many ask for it when purchasing a used amp or instrument?
Why do I ask? It's been my experience, especially with solid state stuff, that it either works out of the box and for years afterwards, or, it goes down right away--right out of the box, in fact. If it blows semi-immediately, the shop where you purchased it should hand you a new one and work out the details with the manufacturer or with the shipper.
If it's been in the field for awhile, we've seen what happens and try to protect ourselves from all kinds of stories.
As an example, I recently had a gent come into the store with a neck that was broken in two, smack in the middle. He stood before me and swore up and down that he was just playing the bass and it snapped. His wife was standing next to him, in total silence. After 15 minutes of peaceful discussions on my part and rants about companies not backing up their products and corporate rip-offs on his, the wife piped up quietly with--"He sat on the bass while it was laying across a chair. He's an idiot. What's it going to cost for a new neck"?
A single incident? Nope. Beer gets spilled in the heads and they come looking for warranty repair. My best--a Mackie board came back with faders that were a MESS. "I don't know what they use for faders but Mackie sucks", said the owner. Upon opening the board we found MANY tiny pieces of green leaves and seeds jammed into the board as if a mouse was building a winter home. The guy was using the board to roll--uhm--"cigarettes" on.
The Bottom Line........a warranty is often as good as the paper that it's printed on and you'd best be sure that the manufacturer that you're buying from believes in their product. MY opinion would be that if Aguilar believes enough in what they're producing to tack ten years onto the "belief in confidence" factor, they're probably going to take care of the product and not look for tiny loopholes as many do.

Your thoughts?
