Hi all, first post here.

My parent’s picked up for me while over seas a Hum Debugger unit. I had suggested a few pedals for noise hum solutions and the Hum Debugger was one of them.

Now I’ve tried it out, and whilst it is awesome at wiping a lot of the noise from my amp/pedals/noisy power points, etc, at higher gain (where I normally play) it introduces a nasty filtering type effect that sounds something like the effect used for the Darleks voices on Doctor Who!

With clean and lower gain tones the pedal really is amazing, but I really need it for the higher gain stuff. Is there any way of solving this horrible filtering problem? If I can’t the pedal isn’t really of any use to me, and I’d feel bad getting rid of it as it was a gift from my parents. I’ve tried the pedal at different points in the chain, and I thought my cables were of reasonable quality (i.e. not the cheap nasty ones, decent jacks, etc – maybe better ones would help).

Any ideas people, I would really like to hang on to this pedal if I can solve my issues.
