I just recently bought a new amp cause I need a light, portable amp on the go for those smaller stages, so I just bought the new Fender Champion 40 1x12. (Loud for a little guy!) The stock speakers just suck! I basically use just the clean channel only with my Tech 21 Hot Plexitone and TC Electronic Flashback X4.

After installing a wonderful 12'' Jensen Tornado, the amp really opened up and has some serious dynamics and definition,very good chunky low end - very spongy feel, kinda like EL84, mids are not very over powering, it has clarity but most of all a very sweet high, creamy top end. The most surprising thing about this is that this amp that has the Jensen Tornado 12" is a solid state amp! Other guitar players on the scene that heard my sound swore that I have a tube amp crank behind me! Go figure that..... Highly recommend Jensen Tornado 12" on solid state amp! It gives it a tube amp feel and sound. It really does give life to a sterile, stale solid state amp.

For a year and a half I was going through all kinds of speakers for my Roland JC120. I've tried almost all the eminence stuff and quit a few Celestions, the only thing that I settled with that came close to what I was hearing was the Texas Heat. It was good but there's still something missing that I was not hearing specially during live gigs. After some researching going on I thought I would give it one more shot and if it does not work,I still have the Texas Heat to fall back on.

So I bought two Jensen 12" tornados for my JC120, after stumbling upon it on line. And after I put it through one gig,I had finally found the speakers that really made me sound like I have some talent! I had warmth and clarity both doing solo works and rhythms. I don't have a very difficult set up,all I got is three Boss pedal, SD-1 to kick in for solos,OD-3 for my main rhythms and DD-7 for some delay. Needless to say I sounded freaking awesome
and Loud!!! I'm glad I took that one last step of the journey! I guess I've been a Jensen guy all along and didn't really realized it....... Oh! and one last bonus,my JC120 is now a lot lighter!!!
