Holy Grail and GFS Retroverb

[Monkus]

I have both these pedals but they've started to hiss horribly. Are there any fixes? I got the biyang baby boom, but a friend made me an offer i couldn't refuse so I sold it. Thoughts?

Have you added anything to your chain? Do they hiss if they're the only pedal connected? Digital pedals often have quite a high power drain and can get noisy on a shared power source.

[Monkus]

stand alone noisy......

[markb]

Odd that they should both be afflicted. I'm lost.

[Tig]

Even with different cables, power sources, etc?

[guitartango]

Did you hiss appear after you removed the Biyang ?

gtr>reverb>amp>>>>>hiss :)

I honestly dont know.... the holy grail comes with its own power supply, and I tried battery and one spot with the gfs but same thing ... I think i'll send both to a tech.
