I've been looking at the fishman loudboxes, and I'm not entirely sure which one to get.

Page three is where the amps are.

I've been to Guitar Center and tried out the second one (Loudbox 100) with my own guitar which I absolutely loved the sound of. The problem is the price tag, which is $600 USD at GC. (I love the amp, but I'd also love to be able to afford other things, like tuition)

If you notice the first option, it is much cheaper, but also discontinued. There is a guy on craigslist selling one for $300.

How much of a difference would there be between the two amps, and why such a price difference? I do notice that the loudbox 100 has an option for an extra microphone instrument or mic, but I don't think I would be using that anytime soon.

Do you think that there would much of a difference in sound between the two?

Would I be better off with a used downgraded version, or should I shell out an extra $300 for the fishman loudbox 100?

Any help or input is appreciated!
