1. INPUT: Use this 1/4” jack to connect your bass to the amplifier by means of a shielded instrument cable.
2. GAIN: Use this control to adjust the amount of distortion for the Distortion/A channel. As you rotate the con-
trol clockwise the amount of distortion increases.
3. SHAPE: Use this control to adjust the tone of the Distortion/A channel, from a studio “V”-shaped tone to a
more “live,” more present sound.
4. LEVEL: Use this control to adjust the output level of the Distortion/A channel.
5. CHANNEL SWITCH: Use this switch to select either channel. With the switch in the out position, the
Clean/B channel is selected. When the switch is depressed, the Distortion/A channel is selected. The adjacent
LED illuminates when the Distortion/A channel is selected. NOTE: When using the footswitch (#18): when this
switch is depressed, the footswitch switches between the Distortion/A channel and the Clean/B channel; when
this button is in the out position, the Clean/B channel is always active, and the footswitch turns the Distortion/A
channel on and off, allowing you a blend of both channels.
6. LEVEL: Use this control to adjust the output level of the Clean/B channel, and as part of the Octave level
control (see #11).
NOTE: The BX25DLX/BX50DLX employs an internal noise gate to keep residual noise to a minimum.
Regardless of which channel is selected, the Clean/B channel’s Level control (#6) must be turned up above
“0” in order for the noise gate to trigger.
7. LOW: Use this control to adjust the low frequency level of the Clean/B channel.
8. LOW MID: Use this control to adjust the lower-midrange frequency output of the Clean/B channel.
9. HIGH MID: Use this control to adjust the upper-midrange frequency output of the Clean/B channel.
10. HIGH: Use this control to adjust the high frequency output of the Clean/B channel.
11. OCTAVE: The BX25DLX/BX50DLX features internal circuitry which creates a second signal which is one
octave lower than the input signal. Use this control in conjunction with the Clean/B channel’s Level control (#6)
to adjust the level of the octave signal.
12. MASTER: Use this control to adjust the overall output level of the amplifier.
