Effect Types and Parameters
ZOOM B1/B1X

■
DRIVE module
Defret
This effect makes the sound of a fretted bass resemble that of a fretless bass. Higher setting
values result in higher effect sensitivity.
Slow Attack
This effect reduces the attack rate of each individual note, producing a violin playing style
sound. Higher setting values result in slower attack times.
Pedal Vox
This effect simulates the half-open sound of a vintage Vox wah pedal. Higher setting values
result in higher emphasized frequency.
This module includes 13 types of amp/stomp box modeling effects and a bass synthesizer.
For this module, DRIVE (effect type), GAIN (parameter 1), and MIX (parameter 2) can be
adjusted separately.
DRIVE (Type)
Selects the effect type for the DRIVE module.
AMPEG
SUPER BASS
Effect modeled on the sound of the
ultimate rock bass amp, the Ampeg SVT.
Simulation of the Marshall Super Bass
head amp that has made rock history.
SWR
ACOUSTIC
Simulation of the SWR SM-900,
famous for its hi-fi sound.
Effect modeled on the sound of the
Acoustic 360 with its tight midrange.
BASSMAN
HARTKE
Effect modeled on the sound of the
Fender Bassman 100.
Simulation of the Hartke HA3500
famous for its aluminum cone.
TRACE ELLIOT
TUBE PRE
Effect modeled on the sound of the
Trace Elliot AH-500.
ZOOM original tube preamplifier
sound.
SANSAMP TS9
Simulation of the Sansamp Bass Driver
DI, highly popular among bass players.
Simulation of the Tube Screamer used
by many guitarists as a booster.
ODB-3
MXR BASS DI
Simulates the ODB-3 overdrive bass
machine from Boss.
Simulates the MXR Bass D.I.+
distortion channel.
FUZZFACE MONO
SYN
Simulation of the Fuzz Face that made
rock history with its zany look and
smashing sound.
This is a monophonic bass synthesizer
(for single-note playing) that detects
the pitch of the input signal.
GAIN (Prm1)
Sets the DRIVE module parameter 1. The parameter type depends on the
currently selected effect type.
When distortion effect type is selected
Gain
Adjusts the gain (distortion depth).

EQ module
■
ZNR/AMP (ZNR/Amp Simulator) module
When MONO SYN effect type is selected
Variation
Allows selection of the oscillator waveform type and tone variation. Available settings are "s"
(sawtooth), "p" (square), and "m" (PWM = pulse width modulation).
MIX (Prm2)
Sets the DRIVE module parameter 2. This parameter is the same for all effect
types.
Mix
Sets the mixing balance between the signal before the DRIVE module and the signal after
passing the module. Higher setting values result in more drive sound.
This is a 3-band equalizer. For this module, the three items EQ LO, EQ MID, and EQ HI can be
adjusted separately.
EQ LO (Prm)
EQ MID (Prm)
EQ HI (Prm)
Adjusts the LO
band of the EQ
module.
Adjusts the MID
band of the EQ
module.
Adjusts the HI
band of the EQ
module.
Lo
Mid
Hi
Adjusts the low
range (70Hz) boost/
cut.
Adjusts the
midrange (450 Hz)
boost/cut.
Adjusts the high
range (3 kHz) boost/
cut.
This module combines two elements. ZNR is a noise reduction circuit developed by ZOOM
which removes noise during play pauses without affecting sound quality. The amp simulator
recreates the sound of speaker cabinets.
ZNR/AMP (Type&Prm)
Selects ZNR sensitivity and amp simulator type at the same time.
ZNR (ZOOM Noise Reduction)
This is the noise reduction function only. Higher setting values result in stronger effect. Set the
value as high as possible without causing the sound to be cut off unnaturally.
AMP&ZNR (Amp Simulator & ZNR)
Combination of ZNR with bass amp cabinet simulator. The right-digit value controls ZNR
sensitivity.
