BX-13
Expanded Bus Converter
OWNER’S MANUAL
_______________________________________
DESCRIPTION
Congratulations on your purchase of the BX-13
Expanded Bus Converter.
The BX-13 combines the technology found in
the Roland BC-13 bus converter but with
expanded footswitch control.
Like a BC-13 Bus Converter, the BX-13 can
convert the vintage 24-pin style signals into
modern, 13-pin control signals, enabling the
vintage guitar synth enthusiast access to the
latest in guitar technology.
Your BX-13 has been hand-built and hand-wired
using quality components for reliable operation
and is backed by a five-year warranty.
Please read this owner’s manual carefully before
using the BX-13.

IMPORTANT NOTES
• When connecting a guitar and
synthesizer to the BX-13, be sure that
power to the synthesizer is switched off.
• The 13-pin connector used with the BX-
13 is locking style, and therefore cables
cannot be disconnected unless the
locking pin is released.

PANEL DESCRIPTIONS
1. Guitar Synth Input: Input for 24-pin
style G-Series guitar cable.
2. Synth Output Connector: The
modern. 13-pin synthesizer output
connector.
3. Synth Footswitch: This switch turns
on and off the volume level for the
Synthesizer. The associated RED LED
will glow when the synthesizer output is
on.
4. Guitar Footswitch: This switch turns
on and off the volume level for the Guitar.
The associated GREEN LED will glow
when the synthesizer output is on.
5. Guitar Line In 1/4”: With only the 24-
pin cable plugged in, the level of the
standard guitar sound is always at
maximum
. If you want to vary the level of
the standard guitar sound, then a second
cable needs to be connected from the
1/4” Guitar Output jack on the Guitar
Controller to the 1/4” Guitar Input jack on
the BX-13. This is the same design used
by the Roland BC-13.

SWITCH FUNCTIONS
The BX-13 changes some the functions of
vintage G-Series controllers to match new, 13-pin
functions.
• Master Volume knob is now for Guitar
Volume only. This knob changes the
volume of the Guitar when a cable is
hooked from the standard 1/4” output
jack on the guitar to the BX-13 guitar
input.
• Guitar Tone Knob controls the tone of
the guitar’s normal sound.
• Filter Knob, or CV#1, becomes the
volume control for the Synthesizer.
• Mode Switch becomes SW1 and SW2.
