I was able to spend some more time with the Wiggler. Seems the pulsing noise can be kept to a minimum if I keep the amp’s gain down. Have to say the Wiggler has some great sounds on tap though. And my unit is quiet as far as “white noise” or “hum” but the pulse from the modulation effect is noticeable.

I guess will have to learn to live with some noise.

Still pretty frustrating that it was missing one of 4 chassis screws. For a nearly $200 pedal I expect more.
