The CV Input
The Geiger Counter’s Key Input can be set to affect the Bit Depth, Sample
Rate or both at the same time. Push the Wave Table knob to set the key
input destination (the LEDs by the sample rate and bit depth knobs will
become green when the key input is active on them). Note that if yellow,
the key input is active while the Sample Rate is in fine mode, or the Bit
Depth is set pre wave table.
The Geiger Counter can use any standard expression pedal, LFO or other
CV (control voltage) source. 0-5 volts ONLY.
For interfacing with CV gear that outputs +-2.5 or +-5 volts, like Eurorack
modular gear or Moogerfooger pedals, we have a cable adapter that runs
off of the Geiger Counters CV input power supply (see below) that safely
converts +-2.5 or +-5 volts to the 0-5 voltage levels needed by the Geiger
Counter. These adapters sell for $30 and are built to order to interface
directly with YOUR setup. Please contact us at info@wmdevices.com
to order.
The Geiger Counter supplies 5.6 volts at the ring of the CV jack, ground
on the sleeve and signal input (CV or Expression Pedal Control) on the
tip. Using a cable without a ring will cause this voltage to be shorted to
ground, and while it will not hurt the Geiger Counter, it will reduce bat-
tery life.

The Company
William Mathewson Devices is a Denver based company
specializing in versatile audio electronics. Our products
have usable knobs that typically extend beyond the “usable”
range in order to encourage experimentation. We strive for
studio quality sound in our pedals, meaning low noise and
low distortion (only when you don’t want any distortion).
We strive to create pedals with strange features and settings
that inspire creativity through unpredictable behavior.
Additional Notes
Power Adapter - The Geiger Counter uses the Boss style 9
Volt power adapter. These adapters have the positive (+) on
the sleve and the negative (-) on the pin.
All pedals have reverse polarity protection, but please check
the power supply before plugging it in.
Using a power supply is recommended as the Geiger Coun-
ter draws 20-30mA. This consumption has been minimized
by design, but is still significant. A 9 volt battery should last
4 to 6 hours and is intended for backup purposes only.
Do not underpower (starve) the Geiger Counter, it will just
make it sound bad.
Warranty - All WMD pedals are guaranteed against defects
for 1 year from date of purchase. If the pedal is deemed de-
fective at fault of WMD, it will be repaired or replaced free
of charge (shipping to be paid by buyer). If pedal is deemed
damaged at fault of buyer, regular repair rates will apply.
