Wow!!! I just got my WT550 yesterday (thanks 5bassman) and it really sounds amazing with my Epi UL410! This will come as no shock to any regular here at TB (especially KJung), but it far exceeded my high expectations! Total rig weight: 77 lbs! You could play anywhere with this one! I was looking for a head that would land between my GK 1001RB-II's SS precision and Mesa WalkAbout's tubey goodness, and run down to 2 ohms...the Eden does exactly that! Oh well, cut me some slack, I'm still in the honeymoon period and haven't gigged it yet. I'll shut up for now, but let us know how you feel about any of the above statements, or just tell me to chill out.
