FEATURES & CONTROLS
IN: This¼”phonojackis theInstrumentInputforthe
device. Plug the Output of your guitar - or an upstream
pedal’s Output - into this jack with a shielded cable of
goodquality.The input jackisa switchingtype jackand
thecircuitisactivatedbyinserting a cable(evenwiththe
footswitchoff).Oncepluggedin,theinternalbatteryisbe-
ingusedtopowerit–sobesuretounplugthecablefrom
theINPUTwhenit’snotinuse.
NOTE: The internal battery is switched to an “ON” state
(drawing voltage) by a switching element in the INPUT jack.
To prolong battery life, disconnect the cable from the ¼”
INPUT jack whenever the unit is not in use.
NOTE: If you wish to leave the INPUT connected perma-
nently – as in a pedal board scenario – it is advisable to
power the unit with an external 9V power supply. When an
external (plug-in) AC 9-volt power supply is used to power
the unit, the DC jack on the pedal automatically discon-
nects the battery to avoid battery wear and preserve its
useful life. If you are going to use external AC power either
for long periods or permanently in a pedal board set-up,
remove the internal battery to prevent (forgotten) battery
corrosion.

NOTE: A Word on Cables… Always use shielded instru-
ment cables of the best quality and shortest length possible
when connecting these types of devices. This will minimize
degradation of your sound, particularly high frequency
roll-off, due to the added capacitance in longer lengths of
cable. We recommend no more than 18-20 feet total (Input
and Output combined) between your instrument and the
termination at the INPUT of the amplifier. If you must use
longer cable lengths, you might consider the use of a Buffer
or Line Driver to keep the tonal integrity intact. While these
change the sound slightly, it will usually be preferable to
top end roll-off. And yes – those little 4” interconnects count
too, so count them in your cable length.

NOTE: Any type of 9-Volt battery will work in this device if it
is fully charged and functional. Carbon Zinc, Alkaline or even
Nickel Cadmium Rechargeable type batteries are all acceptable
replacements. Some pedal aficionados prefer the “sweetness”
they claim to hear from standard Carbon Zinc type batteries,
but you will have to decide what type best serves your needs.
