BT1000 Bass Amplifier Congratulations! You are now the proud owner of the Crate BT1000 Bass Amplifier. The BT1000 features a clean channel with a four-band rotary EQ and a footswitch-controllable Expander circuit for quick tone changes. An active electronic tuner, conveniently located on top of the amplifier, allows you to get in tune and stay in tune "on the fly." The Mute switch allows you to tune in silence without changing the amp’s Level controls.
