Not long ago a few days now, I got a Eden VT300B, owning a Mesa Bass 400+ and Mesa TT800, wanted something different, i I had the Eden E300T before sounded good but really really liked the individual bias per tube (wish the mesa had this) sold it to get a mesa 610 cab (my dream cab since they came out) found the VT300B in reverb at a good price, I got it as I read that also had individual bias, I really liked it better than the E300T, loaded it up with a set of vintage GE 6550s along with vintage telefunken on the preamp, it was tone nirvana to me, the sound is warm, round and can get a little dirty as well, I hooked it up to my 610 and was in love runing my active 5 string basses tru it, didn't had the need to use a 12au7 or t7 to tame the gain using my active basses, I then proceed to hook it up to a mesa powerhouse traditional 410 and sounded even better, the d.i. is pretty good as well, I've read mixed reviews about the Eden, it fit for my liking, I just wish I could find out the preamp tubes function, as I like tube rolling, now I have a set of spare 6550s thanks to the individual bias
