Hi Jeanne Marie,

Sorry to hear that.

Just in case your store cannot help you out, I want to mention 2 pedals with the polarity switch located outside:

1. The Signal Flex pedal (Model # SF2481)

2. The Satar pedal (Model # VST 125)

Both of these pedals are in the $20 US range.

Hope that you can have this problem solved soon.

Regards,

Sean
