Some things I can tell you about Eden:
I have no complaints whatsoever about my WT600. It sounds great and it's extremely easy to set up. I run it mostly with the EQ flat with all my basses and a little bit of 'enhance', a feature typical to Eden amps (sort of a mid sweep). If I have to adjust the EQ, it's mostly to adapt to the room or stage. I really like the sound of Eden, but I can imagine it's not a sound that everybody's looking for. It's clean, well defined, kind of 'HIFI'.
On the customer support: it's fantastic! The Eden forum is a great resource, as is their website. If you're thinking of buying Eden, go and hang out there for a few days/weeks. You'll see what I mean. I once had an issue when I ordered a new cab and it arrived with a broken speaker. I called the distributor for the Benelux and he told me not to worry. I didn't have to go through the shop where I ordered it, because that would take too long. He was going to send me a replacement so I could put it in myself. Two working days later, UPS delivered the speaker. Try that with some other brands!
Of course, people have had issues with Eden, there's not one manufacturer that doesn't make mistakes. But for Eden, it's really difficult to find stories from people that were not satisfied with Eden gear.
If you go Eden, go Eden all the way. Amp and cabs... They're incredible!
