I did a search for a shootout between these two specifically and couldnt find one ... if there is a previous thread, please send the link. Some might think it is like comparing apples and oranges but I will ask anyway. I thought I was all ready to settle on the GK and started reading up on the Eden. I play mostly rock (AC/DC to Tool to RHCP), with some dance & funk (some slapping) mixed in. I was going with the GK mostly because of power and punch for the buck. I use MM Stingrays if it matters. I started looking at the Eden for it's warmth, EQ, and compressor. I was wondering which amp is more versatile ... I still like a clean sound but perhaps with a little warmth that a tube pre could bring. My main problem with the WT-500 is power. I know the GK would probably blow it away but I am wondering if the Eden could get by filling medium sized clubs/bars. Another thing, I noticed the WT-500 doesnt have an input pad ... has this been a problem for active preamp users? Any thoughts would be great!!!!!!!!
