Short story, I have a Laney cub super 12. Main guitars I use for it is Fender AO 60s strat, Gibson Les Paul slash, charvel dk24 HSH.I would consider myself strat guy. Laney seemed very mid focused and sounded muddy with strat. Acceptable tones were with boost engaged and volume turned to 7 (with treble bleed) and almost acceptable clean sound was with Fuzz Face with volume on 7.
With les paul, cranked to 8 and boss sd-1 in front sounded awesome.
So I thought of giving a try to Jensen to get a more pleasing clean sound with start and I couldn't be happier, sounds way more fender, could not believe the speaker makes such an impact.
However, LP now sounds kind of weird, fizzy, the graul seems less aggressive.
My conclusion for Laney cub super is if you want more fender style clean sounds, this seems to do the trick and I am very pleased but if you are more into humbucker style cranked rock sound, the original speaker seems to deliver better.Keep in mind this might have totally different effect on other style circuits.
