Re: 'best' filter for bbd

2012-06-17 by maniacly_depressed_robot

Thanks for the useful and diverse answers!
I have a Carbon Copy mxr analog delay pedal - certainly there must be a kind of cheap lowpass in it to filter out the noise of the delay clock...
I guess it's a more complex kind of a problem. 
What do you think about the pittsburgh modular analog delay?
