The SB1 RG Series represents the older pedals.  To make it easiest to understand, all pedals manufactured prior to August 2011 would be retrograde.  It is not WHEN YOU PURCHASED but rather when it was manufactured.  We understand that it may be difficult to know when your pedal was made.  The best way to know is if you contact Trick via phone.  We will be able to walk you through the steps to knowing what model pedal you have.  Just ask, "I need to know how to tell when my pedal was manufactured so I can buy the SB1".

Since the RG series needs more parts to bring the pedal up to date there will be a cost difference.

The DOMINATOR RG Series requires a modification to be done to the DOMINATOR pedal itself and will be required to send in the pedal for this update.
