DC Power Cables
The Pedal Power end of each supplied DC power cable has a black barrel
connector. The other end has either another identical barrel connector (center
negative), a 5.5x2.5mm red barrel (center positive) or a 3.5mm mini-plug (tip
positive). Use the standard black barrel connector cables with most common 9V
battery operated pedals.
Before powering your pedal with a standard black barrel connector, you must
verify that the pedal requires “center negative” polarity to prevent damage. Some
common exceptions with their power jacks wired for “center positive” are the
Fulltone ‘69, SoulBender, and Octafuzz pedals and Moogerfoogers. Reverse
polarity cables are available from Voodoo Lab to properly power these pedals.
Strymon
All Strymon pedals (including the larger format Timeline) can be powered from
any of the high-current 400mA 9V outputs using a standard black 5.5x2.1mm
barrel cable.
Important: Strymon pedals should only be powered from the 9V outputs.
Attempting to power from a 12V output will permanently damage the pedal. Don’t
do it, we warned you!
Boss Pedals
There are two types of Boss pedals which operate from a 9V battery. These are
identified by the type of power supply specified, either PSA or ACA. Almost all
Boss pedals specify the PSA type adapter and operate at 9V. Boss pedals which
specify the ACA type adapter require a higher voltage and should be powered by
a 12V ACA output (via DIP switches). Boss Twin pedals, such as the DD-20,
require more than 100mA and can be powered from any 9V high-current (250ma
or 400mA) output.
