The BT25 features two different channels: a distortion channel, featuring
Crate's exclusive Shape control for quick and easy access to the tone you need,
and a clean channel with a four-band rotary EQ. Another unique and valuable
feature of this amplifier is the Octave control. This feature electronically
creates a second signal that is one octave lower than the original signal. An
active electronic tuner, conveniently located on top of the amplifier, allows
you to get in tune and stay in tune on the fly. Front panel jacks
are provided for connecting a CD player and a pair of headphones, thereby
optimizing your practice time.
