I did search and decided a poll was in order. It's not my intention to start a gigantic thread or a heated debate. Just a poll and a few experienced guys and gals thoughts. *Disclamer: There is no right or wrong choice. Hopefully just honest opinions. Head to head let's note some differences: Carvin BX500 $399, 300w~8ohm, 500w~4ohm/2ohm passive/active switch, mute switch, made in USA, 1yr warranty, 5.8lbs Eden WTB400 $499, 400w~4ohm, made in China, 2yr warranty, 26lbs.(as per Eden, 15lbs elsewhere) incl. foot switch (Carvin opt.) Similarities include compression, effects loop, tuner out, DI w/ground lift, headphone out, Speakon & 1/4" out and rack plate optional for both. What does the experienced opinion say? Some people don't feel Carvin has been reliable in the past. Others feel weight is a major issue for them. I'd prefer to hear from those who know BOTH amps to some degree. It's taking me a long time to read through the BX500 threads (three massive ones) but I own the Carvin myself. I'm also picking up the Eden very soon. Now, I'm not asking anyone to decide for me. Of course I will do my own comparison and listen, touch, taste, smell etc. But until then I'd like to hear from those in the know..........Thanks gang.
