What is a Tap Tempo Pedal with Polarity Switch?
Easy. A polarity switch is a little flick switch which allows you to choose whether your tap tempo pedal (or any footswitch, for that matter) is “normally open” or “normally closed”.
What’s the difference?
Another easy one. If a switch is “normally open”, then clicking the switch means that it’ll make the contacts touch, and go back to keeping the contacts apart when released. “Normally closed” is the exact opposite: clicking the switch will break the contacts apart, and releasing it will allow them to come together again.
What does it all mean, Basil?
I’ll tell you. Some effects pedals (the Marshall Echohead and the Eventide Timefactor, for instance) require normally open external tap tempos. Others, like most Boss pedals, prefer normally closed (though they can be used interchangeably, most people prefer to stick with the correct type as this means the tap is registered on the down press as opposed to the release of the tap pedal – see the Advantages of a Normally Open Switch video for more details).
So which do I need?
As a general rule of thumb, if you’re using a Boss or Roland product, you’ll be needing a normally closed footswitch. Other brands of effects pedals largely prefer normally open, although this is a bit of a generalisation – without Contacting Us to make sure which one you need, it’s tricky to be sure.

Of course there is, you didn’t think Vein-Tap.com would leave you in the dark, did you?
