Last weekend was my first gig with my WT400. I have it mounted in my custom made 210 combo. The cab is 8 ohm, so the Eden will only put out 235 watts. We normally do not play at a very high volume onstage at our gigs, but this last weekend proved to be the exception. We were missing one of our players and we decided to just crank it and jam the night away. I have an extension cab and I thought perhaps I might need it. But I was pretty surprised by how much volume could come out of my 210 cab. I had the amp set up flat, with the enhance set at about 12 oclock. I had the gain set to about 9 or 10 oclock and by the end of the night I had my master cranked wide open. The WT400 has such a great tone that I only had to do some very minor tweaking for the room I played in. I cut the low by only one click and I had the high cut by two clicks. With everything else set flat, I was getting a very full, warm sound with just enough brightness to cut through perfectly. I play a Fender P-Bass with roundwounds. There were times that I was really getting a nice growly and clanky Rick thing happening. After our second set, my guitarist even made mention of it. He said it sounded like I was playing a Rick coming from a P-Bass? If I really dig in up around the neck, I can get this kind of tone. If I play more over the pick-up or the bridge it still has that classic P-Bass tone. There were a few songs where I mute my strings and I got an awesome dub sound I never really nailed before. I also got a very cool, almost fretless kind of mwah happening, when I played very close to the bridge. I played around all night, experimenting with the tonal variety I was getting out my bass. I never got that kind of tonal variation out my Hartke HA4000 no matter how I messed with the settings or how I played my bass. We were stupidly loud. We never play at that high of a volume, but the bar, the crowd and the night just seemed to call for it. The crowd made comments on how good the sound was and apparently we werent all that loud out front as many said they appreciated the fact that they didnt have to yell in conversation, and the bartenders said that they too could hear drink orders, but we sounded great. So we were cranking on stage, but not out front as much. Im just amazed at how much this amp puts out into a 210 cab. I never needed my extension cab. I cant imagine how loud it would be with it cranking out the full 400 watts into 4 tens. The WT400 gives me a straight up sound that allows me to vary the tone by how I play rather than having to settle for one tone no matter what. This amp is just awesome for me. All of the notes on all the strings have this full, solid thump you can feel, but with a rich, cutting (but not overly bright) tonality over it. My Hartke HA4000 gave me an adequate sound, but with the WT400 it was like taking a blanket off my cab and letting the real tone come out. My sound just came alive with this head. I waited for over three years to where I could swing an affordable deal to get an Eden head and I wont ever be going back to anything else. Eden makes some very high quality ampheads. I cant wait for the next gig!
