I wanna replace the rocket 50 speaker in the 20w blackstar combo what would you recommend? Ive heard the v30 dont sound good as a single speaker in a combo,?

I like an old and justice for all thickness, maybe a lil janes addiction flavor with lots of verb and delay, but never clean as clapton i use EMGs with a viper thanks so many choices i dont wanna make the wrong decision !

I do know that rocket fifty doesn't do justice to that amp!
