About the BP90

Performance Mode

When you first apply power to the BP90, it powers up in Performance mode. Performance mode
provides access to all of the presets within the BP90 via the Up and Down Footswitches. The
Edit Up/Down buttons cycle through the effects in the matrix.

Edit Mode

When you select an Effect with the Edit Up/Down buttons, you can adjust the Effect with the
Value Up/Down buttons. (For descriptions of the Effects and their parameters, see page 20.)
When you make changes to a preset's Effects, you must store the changes or they will be lost
when you select a different preset or disconnect power to the BP90. See page 17 for a description
of the Store procedure.
The BP90 presets can be bypassed for a clean, unprocessed bass signal. To bypass the BP90, press
and release both Footswitches simultaneously. The Display reads By indicating the preset is
bypassed. In Bypass mode, all buttons are disabled. Press either Footswitch to exit Bypass mode
and return the BP90 to the last preset used.

Tuner Mode

The Tuner in the BP90 allows you to quickly tune or check the tuning on your bass. Enter Tuner
mode by pressing and holding both Footswitches simultaneously. The Display briefly shows tu
indicating that you are in Tuner mode. To begin tuning, play a note on your bass (a harmonic at the
12th fret usually works best). The Display shows the note being played. The Matrix LEDs indicate
whether you are sharp or flat. The left 6 red LEDs indicate the note is flat and should be tuned
