Bought this in 2015 and gigged with it a few times but my direction has changed and this fine piece needs a new home. This is a "C" model. Can run 2 channels/sides @ 2ohms, supplying each channel/side 550w. Or bridge for 1100w at 4ohms. Bi-amp mode is available if you prefer, you select the crossover point. Speakon and 1/4" speaker jacks. Very flexible pre-EQ and post-EQ effects loops. Here's the FS thread from where I purchased it:Eden WT-800 C Bass Preamp/Amp - Like New! Manufacture date is 3-30-07. This is a Made In USA amp, and is in excellent shape. I will update this thread with my own pictures in a few days (there are multiple pics on the thread linked above). Price includes shipping and insurance. I will ship double-boxed and well-packaged with foam layers; there will be no "wiggle room" in the box. Thanks!
