Behringer's Ultrabass BXL450A is the ultimate practice amp. A wedge-shaped bass cab houses a 10" Hard Attack aluminum-cone speaker and has 45W of output. It is a perfect size for practice or backstage warmups. It provides a clean and a distortion channel, each with full control. Its 5-band active EQ features a revolutionary See-What-You-Play FBQ frequency indicator that immediately shows you which bass frequency corresponds with which fader on your EQ allowing you to instantly trim your sound. A headphone jack lets you keep your practicing to yourself, while a CD input lets you practice along with the big boys.
