I just got my first reverb pedal which is a Hardwire Supernatural. As soon as I added it to my board, I got a terrible hiss. Is this the pedal itself or is it a problem with the way I am powering it? Here's my setup: Keeley Comp, Boss BD-2, Timmy, Korg Pitchblack on VS One Spot daisy chain Line6 G30 wireless on its own wall wart power supply Vox DelayLab on its own wall wart power supply Supernatural was tried on its own 200 mA wall wart, then chained with the One Spot, then in place of the DelayLab so I could use its 300 mA wall wart. The hiss remained with all these options, though I think it might have been a little less when I took out the DelayLab and used its power supply. My board has always been silent until I added this Supernatural pedal. Is the pedal defective? Is this problem fixable with a different power supply? Anyone else have this problem?
