Out Of The Box!
Thank you for buying one of our Chameleons! Before you take it out and perform with
it ‘in the wild’, we wanted to explain a few things so please bear with us. We know
reading instrucon manuals can be a chore.
We know you might want to get started with this straight away, so we have adjusted
the default sengs accordingly. This means that, using the ‘Quick Start Guide’ (in the
box and also available online either in our Complete Instrucons or separately), you
can be stomping within minutes using the percussion surface, either with your foot or
hand.
One of the best things about the Chameleon is that it can be as adaptable as you need
it to be and the more you learn about it, the more you can do.
It is a 3 channel device. This means you can play sounds using the touch sensive
surface, plug in an external stomper to the mono jack socket (AUX) in order to trigger
sounds this way, and use the (Login) 3rd input to add in an external instrument—this
could be your guitar or even another stomper.
You can load your own sound samples (including drum loops or backing tracks) onto a
micro SD card by transferring your sounds from your computer using a card reader.
Want a simple, plug-and-play kick-ass stomper that adds amazing thud and bass beats
to your music? No problem. Want to use your faithful old Logarhythm footdrum whilst
the Chameleon plays your snare sample and mix your guitar through Login? Easily
done. Don’t have enough inputs on your amp and want a 3-piece drum kit? The
Chameleon’s got your back. It’s even got a rechargeable baery which will last you
approximately 24 hours, so you don’t have to worry about doing outdoor gigs where
power sources may be limited.
However you want to get started, it’s OK. Scan through the Quick Start Guide and get
stomping. Take a seat and read through the Complete Instrucon Manual in depth
and learn all the secrets in one go… that’s ne, too. It’s shorter than War and Peace. Or
print o the Chameleon Menu Structure , pin it up on the wall and study it instead of
watching TV. That’s what the Chameleon is all about, at the end of the day— doing it
YOUR WAY.
Have fun! And if you want to get in touch with us, call ([phone]), email
([email protected]t) or send a carrier pigeon. We are always pleased to hear from our
customers with comments, suggesons or quesons.

Logjam Chameleon Channel Overview
The Chameleon is a 3 channel device. Please refer to the ow diagram on page 6, and
to the brief descripon below:
Channel 1 (internal) is set up for you to play samples using the touch-sensive
percussion surface of the unit itself.
Channel 2 or “AUX” is set up for you to trigger sounds from an external stomper via
the 3.5mm mono jack socket. You may need to use a cable with a 6.35 mm jack at
one end and a 3.5mm at the other end (you can purchase these on our website).
Channel 3 or (Login) allows you to mix in an external instrument. You could, if you
want, put another stomper through this input but you could equally put a guitar
through this jack. This input has a tone control so that you can adjust the tone of
your instrument on this channel.
All three channels access the same balanced Neutrik combo “LogOut” socket. This
allows you to use either a standard guitar cable or a balanced XLR cable. You will
need a male to male adapter if you want to use an XLR cable.. (These cables are
available on our website: www.logjam.net).
We will now show you how to use the unit. In order to make things simple we will
give you separate instrucons for each channel and for the global sengs. Upon
turning the unit o, your sengs will automacally be saved. If there are any terms
that you are unfamiliar with (such as impedance), please refer to the glossary on
page 15.
To switch on, hold and press the power buon ( to switch o hold the buon and
conrm on the menu select buon)
Now please turn to the next page ...
NB: Push menu/select knob for approximately 3 seconds at ANY me to
return to main menu.

Channel 1 (Internal) Instrucons
1) Trigger On/O : This determines whether the touch sensive surface of the
unit will be switched on or o. Push to select then turn for on/o. Push again
to conrm and exit. Turn for next menu item.
2) Select Sample : This allows you to select from a menu of preset samples and
also those you may have programmed into a micro SD card. Push to select item
then turn to select samples. Push twice to conrm your choice . Turn for next
menu item
3) Set Volume: This determines the channel 1 volume. The graphic image shows
minimum to maximum from boom to top of the display. Push to select item.
Turn to select the desired volume then push again to conrm and exit. Turn for
next menu item.
4) Retrigger Delay: This determines the me it takes in milliseconds before you are
able to trigger the selected sample again. A typical useful value would be 50
ms. Push to select item, turn to select value then push again to conrm and
exit. Turn for next menu item.
5) Peak Threshold: This determines the level below which the unit will not trigger
a sample. This is necessary to avoid samples being triggered by background
noise. The level has a seng between 1-100. Push to select item, turn to select
value then push again to conrm and exit. Turn for next menu item.
6) Max Peak Value: This seng limits the peak volume of the sample selected. It is
handy in order to avoid feeding too high a signal into your amp/mixer. This
seng has a range of 1-100. Push to select item, turn to select value then push
again to conrm and exit. Turn for next menu item.
7) Preamp Gain: This seng is similar to the gain seng on a mixer or amp. It

Push to select item, turn to select value then push again to conrm and exit.
Turn for next menu item.
7) Peak Threshold: This determines the level below which the unit will not trigger
a sample. This is necessary to avoid samples being triggered by background
noise. The level has a seng between 1-100. The lower the level, the more
sensive the unit is; for example a small shue of your foot or a sound in the
background. Push to select, turn to select value then push again to conrm and
exit. Turn for next menu item.
8) Max Peak Value: This seng limits the peak volume of the sample selected. It’s
handy in order to avoid feeding too high a signal into your amp/mixer. This
seng has a range of 1-100. Push to select item, turn to select value then push
again to conrm and exit. Turn for next menu item.

General Informaon
Power & Charging
The Chameleon takes an 18650 Li-ion baery . These are readily available but you
can also purchase them from our website. The unit can also run from a standard
Android phone charger which aaches to the micro USB socket on the front panel.
This is also used to charge the baery.
Micro SD Card & Samples
The unit comes with 10 preset 16 bit samples (44.1 khz) which are in the internal
memory . These are idened on the display with 2 underscore lines. These drum
samples have been especially created by experienced UK session drummer Terl
Bryant. We also have a micro SD card available with a large range of samples (also
created by Terl Bryant) which is available from our site.
You can record your own samples and loops, of course. These should be at 44.1 khz
and 16 bit.
Care of Your Chameleon
The Chameleon is made from high-quality Sapele wood. When it gets to be a lile
worn you can lightly sand the wooden area and renish with Linseed oil applied
sparingly with a so cloth. Be careful not to get any oil on any other area of the unit.
We would also recommend that you always transport your Chameleon in the
provided gigbag as this will help to prevent any possible damage.
NB: Push menu/select knob for approximately 3 seconds at ANY me to
return to main menu.

13
Mute Funcon
We have installed a mute feature on the Chameleon which is a useful on-stage
funcon that will prevent any signal going to the amp or mixing desk at all. To use
this feature, scroll through the main menu past Global to Mute. To turn the mute
funcon either on or o, simply press once to toggle (either on or o) and then push
again to conrm. You can then exit the mute menu by scrolling out of it or a long
push will return you to the Chameleon default screen.
NB: Push menu/select knob for approximately 3 seconds at ANY me to
return to main menu.

14
Baery Indicator / Charging
Your Chameleon has an operaon mer which is the vercal line on the le hand
side of the display. This is a 24 hour mer which counts down 24 hours of the unit
being on. This will gradually get smaller over me. When the Chameleon has been
running for nearing 24 hours, this bar will begin to ash and upon reaching the 24
hour mark, will disappear completely. You may have baery life le aer this mer
has disappeared, but to ensure you have 24 hours’ worth of use, you may wish to
charge your unit at this me.
If the baery becomes crically low, your Chameleon will display the following
messages on the screen:
WARNING
LOW BATTERY
SAVING STATE
Followed by:
WARNING
POWERING DOWN
STATE SAVED
20 sec.. (counng down)
This countdown will start at 20 and when it reaches 0, will turn the Chameleon o
automacally. If, during this countdown, or low baery alert, you plug in the unit to
charge, the warning will disappear and the unit will begin to charge. You may
connue to use the unit whilst it is charging. When you charge the unit, the
operaon mer will ash on and o to indicate that it is successfully charging. When
the Chameleon is fully charged, the operaon mer will stop ashing. The operaon
mer is NOT a baery level indicator.
NB: Push menu/select knob for approximately 3 seconds at ANY me to
return to main menu.

Glossary of terms
Channel 1 - This is the internal channel of the Chameleon and allows you to play
samples using the touch-sensive surface of the Chameleon itself.
Channel 2 - (AUX) allows you to trigger sounds from an external stomper via the 3.5mm
mono jack socket.
Channel 3 - (Login) allows an external instrument to be plugged in to your Chameleon.
Gain - Gain is the level of the signal that is being fed into the internal electronics. If you
increase the gain, you will increase the signal you feed in, and vice versa.
Impedance - Audio devices are either high or low impedance, guitars typically are high
impedance whereas a dynamic microphone will be low impedance. However, if you are
unsure of the impedance of the instrument you are plugging in to the Chameleon you
can try experimenng with the other impedance seng. Also, if you nd that you are
geng too weak a signal or alternavely too high a signal, you can try toggling the
impedance to see if there is an improvement.
Neutrik Combo Socket—This is a high quality socket made by Neutrik. The advantage of
this is you can plug in a standard guitar cable (1/4” 6.35mm) or alternavely, an XLR
cable. An XLR cable is a 3 pin cable and the advantage of this is that it is a balanced low
noise cable and will help to get rid of any extraneous noise. If you wish to use the XLR
opon you will need a XLR male to male adaptor (available to buy from our website at
logjam.net)
