I've had a WT-400 since late '97. I also had another, later 400 and an earlier WT-600. If you leave the Enhance all the way off and set the EQ to the nominally flat settings, it sounds "right" to me. Those settings worked well withe Eden D410XLT, which had a noticeable mid hump I liked, but alsovworked well using a pair of E/A VL208 cabinets, a much flatter sounding cabinet.
My take is the amp is fairly neutral, unlike any SWR I've played, and the "Eden sound" is more due to their cabinet voicing.
Spelling, grammar, and punctuation matter!
