reverse logarithmic (or inverse logarithmic) taper the volume comes in very quickly at the beginning
of the treadle’s sweep, but then increases slowly toward the end of the sweep. See the aqua curve
for an example. A linear taper has the same volume change per treadle movement all the way
through the sweep, such as the blue curve.
The VPM-1 has five different tapers to choose from: 2 logarithmic tapers, 2 reverse logarithmic tapers,
and a linear taper. Pressing the taper button cycles through all five tapers. The color of the LED
indicates which taper is currently selected. Figure 4 gives a visual reference for all five curves and their
corresponding LED colors. Once you find the taper that you like best, hold the button down for three
seconds to store it as your “preset.” The VMP-1 recalls its stored preset every time it is powered up.
6. TUNER/EXP JACK
The standard VPM-1 (no expression upgrade) uses the TUNER/EXP jack as a tuner output. When the
Expression upgrade is present, it is used instead as the expression control voltage output. See .
The header labeled “TUNER” on the main PCB must be jumped in order for audio signal to be routed
to this jack. This jumper is already in place if you ordered your VPM-1 pre-built. If you ever need to
remove this jumper, the chassis must be taken out of the pedal in order to access it.
The signal going out of the tuner jack is a unity-gain buffered signal taken directly from the input jack;
no other processing has been done to this signal. In this regard, the tuner output can be used as a
signal splitter to drive another effects chain.
