10. Footswitch Jack: Allows connection of a ¼" terminated single button footswitch
(non-included) in order to turn the FX Loop on or off.
11. Input Gain Control With Clip LED Indicator: Adjusts the input level signal gain
of the BPDI while the Clip LED Indicator will illuminate when too much gain
creates preamp clipping (usually undesirable).
12. -10dB Input Pad: Switch reduces input sensitivity for use with active electronics
basses or high output pickups.
13. 4 Band EQ:
Low: This control increases or decreases bass frequencies.
Low Mid: This control increases or decreases low midrange frequencies.
High Mid: This control increases or decreases high midrange frequencies.
High: This control increases or decreases treble frequencies.
Note: At 'noon' setting on the knob there is no boost or cut applied to the
specific frequency band.
14. Acousti-comp™ Button: Activates the built-in compression circuit. When it
is activated the Clip LED will now light to indicate when the signal is being
compressed and will no longer indicate Input Gain Clipping. If you wish to
increase the amount of compression, increase the amount of signal fed into the
compressor by turning up the Gain control till you see activity on the Clip LED.
15 Shape Button: decreases the level of mid frequencies quickly creating an
alternate EQ curve when engaged.
16. Frequency Notch: Control adjusts the notch filter center frequency from 50Hz
(left) to 1kHz (right) creating an EQ notch cut at the desired setting. Note: The
'noon' setting on this knob is the default, but experiment with this powerful tone
shaping control to enhance slap or pop techniques and remove sounds like fret
noise or roll off the high end for a more vintage tone.
17. Volume Control: adjusts the overall volume level of the effected signal output
by the BPDI.
18. Overdrive Controls: Set the amount of overdrive and the blend of the clean
signal with the overdriven signal.
Level: Adjust the amount of overdrive gain being generated by the circuit.
Blend: Controls the mix of the overdriven signal vs clean signal.
19. Overdrive Footswitch: Turns the Overdrive circuit on or off. Note: This control
will engage the overdrive whether or not the Preamp is in Bypass mode, meaning
the BPDI can be used solely as an overdrive pedal if desired.
20. Bypass Footswitch: Disengages the preamp circuit (Gain control, Acousti-
comp™, EQ, Shape, Notch Filer and Volume controls are disengaged) leaving
the signal going through the BPDI unaffected. This functionally turns the BPDI
into a regular DI with no tone shaping applied.
