Best fender portable amplifier

This is the best Fender portable amp, cause it has real springs reverb, overdrive and a bit of EQ and it's loud enough to play with a band but can be played at house volume too. Very nice fender sound you can play it for any kind of music Blues, Jazz ans Rock metal etc... I know the amplifier is a 2004 and the guy changed the speaker for an eminence for fender, i like it but i plan to change it to Eminence canabis rex.
