I'm having an issue with this Reverberation Machine I recently picked up from Death by Audio. There seems to be a tremendous amount of hiss when I turn the REVERB knob past 12 o'clock, to the point where it's too overbearing, so I keep it dialed in around 9 o'clock. I was running it on a chain with two other pedals, and this problem only occurred when the reverb pedal was engaged. Is this a common problem with reverb pedals in general? Does anyone have any suggestions? The amp I'm playing it on, a Vox AC4C1-BL, is practically brand new. I did a little research and saw that another user was having a similar problem:


I've reached out to DBA and waiting to hear back. Thank you for reading and I look forward to hearing from you.
