Bypass effects for the pedal register
mm
Set the Pedal switch to Byp. If you choose FX, the entire output of the organ is processed.
Bypassing the Distortion, Wah, and EQ effects separately for the pedal register avoids suppression
of the bass portion of your organ sound by the Wah effect. It also avoids intermodulation
artifacts when the Distortion effect is used.
Vintage B3 EQ
Vintage B3 features a simple but effective EQ section.
Vintage B3 EQ parameters
••
EQ On/Off switch: Turn on or bypass the equalizer.
••
Output Level knob: Rotate to adjust the overall EQ level.
••
Low knob: Rotate to adjust the level of the low frequency range.
••
Mid knob: Rotate to adjust the level of the mid frequency range.
••
High knob: Rotate to adjust the level of the high frequency range.
Vintage B3 Wah effect
The name wah wah comes from the sound it produces. It has been a popular effect with electric
guitarists since the days of Jimi Hendrix. The pedal controls the cutoff frequency of a bandpass,
lowpass, or—less commonly—highpass filter. The wah pedal is also used extensively with the
Hammond organ.
For the most dynamic and musical performance of the Wah effect, consider attaching an
expression pedal to your MIDI master keyboard. Your master keyboard should transmit MIDI
control change #11, which would normally be used to control Vintage B3 volume while playing.
Vintage B3 Wah parameters
••
Wah On/Off switch: Turn on or bypass the Wah effect.
••
Sweep MIDI Ctrl pop-up menu: Use to assign a MIDI controller to the Wah effect.
••
Type pop-up menu: Choose one of several Wah effect types.
••
Classic Wah: This setting mimics the sound of a popular wah pedal with a slight
peak characteristic.
••
Retro Wah: This setting mimics the sound of a popular vintage wah pedal.
••
Modern Wah: This setting mimics the sound of a distortion wah pedal with a constant
Q(uality) Factor setting. The Q determines the resonant characteristics. Low Q values affect
a wider frequency range, resulting in softer resonances. High Q values affect a narrower
frequency range, resulting in more pronounced emphasis.
••
Opto Wah 1: This setting mimics the sound of a distortion wah pedal with a constant
Q(uality) Factor setting.
••
Opto Wah 2: This setting mimics the sound of a distortion wah pedal with a constant
Q(uality) Factor setting.
••
Resonant LP: In this mode, the Wah works as a resonance-capable lowpass filter. At the
minimum pedal position, only low frequencies can pass.
••
Resonant HP: In this mode, the Wah works as a resonance-capable highpass filter. At the
maximum pedal position, only high frequencies can pass.
••
Peak: In this mode, the Wah works as a peak (bell) filter. Frequencies close to the cutoff
frequency are emphasized.
