These pedals are not being used with a guitar. They are being used as studio effects with a console. The PSUs with both UltraTap and H90 are SMPS wall warts. They take 100-240VAC in and output VDC respective to the needs of each pedal. And again, this problem only occurs when the UltraTap and H90 are connected to the same pedal PSU. A thorough process of elimination has narrowed the problem down to the UltraTap. So I am asking if anyone is using an UltraTap or another pedal in the same series with other digital pedals and connecting them to the same pedal power PSU and whether or not you are experiencing a noise issue.
Thanks!
