So Ive been doing some research concerning both pedals and Im leaning toward the Dr. Q. Want I want in my envelope filter is a relatively cheap (not much more than 100$) and subtle sound. Just something subtle to add to my sound, not the more obtrusive 'quacky.' filters. So which one of these could get what I want. Ive read many people say the Dr. Q can do this, but I would just like a finalized opinion before I purchase it. And by all means, if anyone knows of a similar pedal feel free to share.
