I've been using Sovteks in both my Mesa 400's for years. Yup the ones in the red/wht/blu boxes. So it's time to get a new set and I run down to find a new Sovtek blu/wht box that says WXT on it. I get back to the jam pad and plug 'em in to find they sorta suck! Boy these new versions are real glassy...too much shrill and not enough beef. I don't like them. Has anyone else used them yet?
