including logarithmic, linear, and reverse logarithmic. Next, we’ve included a “reverse” feature that
allows you to reverse the treadle action. Finally, one of the most useful features of this mod is the ability
to program the pedal positions for minimum and maximum volume, which allows you to set the active
range of the pedal’s sweep.
The VPM-1 comes standard in mono configuration, but stereo configuration is available with a small
add-on upgrade board. In the stereo configuration, the VPM-1 can operate as either a traditional
stereo volume pedal where both audio channels get louder and quieter together, or it can operate
as a “pan” pedal, where one audio channel gets louder as the other gets quieter. Pan mode enables
the user to pan between two different signals. Another add-on upgrade board gives the VPM-1 the
ability to be used as an expression pedal, with programmable settings to accommodate the different
expression jack wiring configurations found on a wide range of effects pedals.
For a complete discussion of the VPM-1’s features and controls, please see the VPM-1 Owner’s Guide,
available from www.zeppelindesignlabs.com.
If you ordered the Stereo upgrade or Expression upgrade with your VPM-1 kit, you will find their parts
in their own labeled packages. This assembly manual describes the assembly of these upgrade boards
right along side the main board. If you didn’t opt for either of these upgrades, just ignore the assembly
instructions for these boards.
