Instruction Manual
EffEc
Here are some brief descriptions of 
the effects included in the Multiwave 
Bass Distortion. The 
EFFECT knob 
settings are split into two major 
categories: 
MULTI BAND and SINGLE 
BAND. MULTI BAND
 settings use 
the band splitting discussed in the 
feature section and the 
SINGLE BAND 
settings do not. Each main category 
contains 3 sub-categories: 
NORMAL, 
FOLDBACK
, and OCTAVE. For each 
sub-category, turning the effect knob 
clockwise tends to produce more dra-
matic effects. 
I BAD 
A 1-3
These three settings are best for 
maximum clarity when playing mul-
tiple notes. These distortion curves 
are similar to standard distortions.
fDBAcK 4-9
The foldback of the distortion curve 
greatly increases the distortion com-
ponents for these settings. The higher 
numbered effects have more foldback 
creating even more distortion.
cAE 10-14
Settings 10 and 11 give the purest 
octave effect. Settings 12 through 14 
also have foldback and can get pretty 
strange. Dial down the guitar volume 
knob for a different range of sounds.
IGE BAD
A 15-16
These two settings are fairly conven-
tional distortion sounds.
fDBAcK 17-19
With the entire bass signal processed 
through a single foldback distortion 
curve, there will be much more 
intermodulation-type distortion 
produced. These are great for getting 
synth-like sounds and work well with 
long sustained notes.
cAE 20, 21
20 is the purest single band octave 
effect, and 21 includes some foldback.
c
EffEc (A)
The effect knob selects which effect 
type will be used. There are 21 effect 
positions around the knob as well 
as a setting for 
CALIBRATE. For 
information on the individual settings 
see the next section. See the Use with 
Hot Hand section for information on 
calibration.
cEA EE (B)
This controls the level of the clean 
signal. Having a separate control for 
the clean level allows you to balance 
the clean/distorted mix. The pure 
distorted signal tends to lose some of 
the precious low frequency content. 
The clean signal can be used to add 
it back in.
DIE (c)
The DRIVE control adjusts the gain 
of the signal going into the distortion 
section. The higher the 
DRIVE, the 
more distorted the signal. 
DII EE (D)
Adjusts the distortion level. This is 
useful for setting the level of the 
effect compared to the bypass signal. 
Note that because the effect com-
presses the signal, the dynamic 
range of the distorted signal will be 
less compared to the dry signal. This 
should be accounted for when setting 
levels.
/ff 
The ON/OFF switch engages or 
disengages the effect. When the 
effect is engaged, the 
ON/OFF LED 
(E) will be lit. The LED will be off in 
bypass mode. The ON/OFF switch 
is also used to start the calibration 
routine when the 
EFFECT knob is set 
to 
CALIBRATE. See the section on Use 
with Hot Hand for more details.
BEhIG
Noise:
Low Power  Change batteries or plug in a DC power supply.
Near noise source  Move pedal away from power supplies and other   
  equipment.
Other equipment  Remove other effects from signal chain, 
  see if noise persists.
Bad cables  Swap out audio cables.
Low volume:
Low power  Change batteries or plug in a DC power supply.
Hot Hand doesn’t work:
Low power  Change batteries or plug in a DC power supply.
Not calibrated properly  Calibrate the Hot Hand (see Use with Hot Hand).
Not connected  Check Hot Hand connections.
Knobs don’t work /light up:
Low power  Change batteries or plug in a DC power supply.
Wrong power supply  Use correct power supply (see Quick Start).
Corroded input cable plug  Check input cable plug for corrosion on sleeve,   
  swap out cable if necessary.
TRS (stereo) cable used  Only use mono cable for input cable.

1. E
   To power the unit, insert 4 AA batteries (included) or connect a 
Source Audio 9V power supply to the 9V DC jack (A).
2. GIA/ADI cEcI
   Next, plug your bass guitar (or other instrument) into the jack 
labeled GUITAR IN (B) via a standard ¼-inch cable. Connect your 
amp (or other audio device) to the GUITAR OUT (C) jack, again with a 
standard ¼-inch cable. Both input and output are mono signals. 
   Note: The unit will not power up until a ¼-inch plug is inserted into the 
guitar input. This is to conserve power when the unit is running on batteries. 
Don’t forget to unplug the cable from the input when the unit is not in use—
otherwise the batteries will continue to drain.
3. E I ()
   To use your Multiwave Bass Distortion with a Hot Hand sensor: Con-
nect the sensor to the SENSOR IN (D) jack and follow any instructions 
supplied with the sensor.

(see Controls section for more details) 
 • CLEAN LEVEL adjusts the clean (no distortion) signal level.
 • DRIVE the amount of distortion gain applied to the signal.
 • DISTORTION LEVEL adjusts the level of the distorted signal.
 • ON/OFF engages and disengages the effect. In calibrate 
mode, the ON/OFF switch starts the calibration.

If possible, dispose of the device at a recycling centre. Do not dispose 
of the device with the household waste.
