i currently have an eden 410xlt and a swr triad. they both sound very good. just getting the gear itch...thinking about selling both and going with something else. i play mostly rock and roll, with a passive fender p and j. suggestions? in the near future, i am also going to retube with jj's. any pre-amp tube suggestions? i'm also broke, so if i can't get a REALLY big improvement...say so. thanks.
