Catalinbread CB Tap 

To use the CB Tap with another pedal (even simultaneously as the Deluxe): Plug one end of the 1/4” TRS cable into any non-Boss pedal’s tap out and plug the other end into the “Tap” input of the CB Tap, then start tapping. The LED indicator will not light up when using non-Deluxe pedals.

The CB Tap will set a delay time which can then be multiplied into uniform subdivisions by adjusting the "Echo Delay" knob. 
One caveat to note is that the CB Tap will not tap anything outside of the Belle Epoch Deluxe’s delay range. For example, it will not tap slower than 800ms. This caveat only applies when tapping the Belle Epoch Deluxe.
