Wrong polarity?
A polarity changing
adapter is available
from Ramble FX.
1. EXPRESSION PEDAL (continued)
If a connected expression pedal cannot turn ON expression control (Fig. 10), try calibrating it as
described on page 17. If that fails, or expression control still will not turn ON, the polarity is most
likely wrong and the expression pedal should be
DISCONNECTED
. It is safe to try because Kismet has
over-current protection, but do not leave it connected.
REQUIRED CONNECTION POLARITY
:
Tip-to-wiper (see Fig. 7). Not all pedals use
this polarity. Expression pedals with the wrong
polarity can be made compatible with a
polarity-reversing adapter, available at
www.ramblefx.com/polarity-adapter
.
Required polarity: tip-to-wiper

2. VOLUME PEDAL
A volume pedal is a foot-controlled potentiometer with separate input and output connections. A
voltage enters one jack and a fraction of that voltage is sent out the other jack. It usually has a
logarithmic (audio) curve, or sweep (Page 15). Most volume pedals are compatible with Kismet.
