The Fender Rumble 25 bass amp is a great choice for practice and even home studio recording, with a beefy low-end (they don't call it "Rumble" for no reason...) and a headphone jack for silent practice. A specially-designed Jensen speaker and newly designed power amp put out some serious bass, even though the amp itself is rather compact and light-weight. Switch on the special overdrive channel for grinding distorted tones that rock with the best of them, and and jam along to your favorite songs on your MP3 player or laptop using the aux input to really nail down those difficult parts.
