Envelope filters are a persnickety lot. I hear awesome tones in recorded songs, on YouTube demo's (usually solo'd jazz bass), even at some live concerts, but it in my own live use, they can be hard to use with my heavy hand and usual P bass preference. So which ones are more "forgiving" for a club gig, where you don't have to concentrate too heavily on technique or have additional volume boost to get a good, noticeable sound?
