From the company that invented the electric bass amp, the The Fender Rumble 25 V3 Bass Amplifier is a mighty leap forward in the evolution of portable bass amps. Its diminutive stature leaves the heftiness to its sound output, not its weight. Rumble 25 uses every last electron of its 25 watts to pump out a surprisingly rich and balanced sound. Plug in your MP3 player into the 1/8 inch Auxiliary input jack and you're ready for showtime. Or practice privately with the 1/4 inch headphone output jack that also mutes the speaker output. This amp features a 3 band EQ that allows for tone shaping. Whether it"s for an acoustic gig or backstage rehearsal, Rumble 25 delivers legendary Fender tone in a remarkably portable package. Its dimensions are 15.1x19.25x20 inches and it weighs 22.8lbs
