Buzzy Overtones with OD Pedals?

[aziltz]

The truth is that when you have a bright sounding amp when clean, there is way more chance that your pedals will sound buzzy. That's why you need to compensate with low pass filters. You would be amazed at how much highs you might need to cut to make a pedal sound smoother.

Quite true.  And we're not talking silly little 1-pole filters either.  You need some serious multi-pole lowpass filtering to keep the fizz out.

well i took your advice and seemed to have fixed my problem.  I put a bass roll-off between gain stages and a two pole treble roll-off after the final stage.  Now I've got something i can work with!
