This is a point of interest to me because I've always experienced difficulties with volume pedals, and as far as guitar work, it's a very important part of the chain. I've had DeArmond and Boss "passive" pedals, which are just a pot in a box, and almost immediately they become scratchy and I always feel the bottom end is never quite "off". Much better results with a Boss ME-8 I had where I could use a pedal as control input to electronic volume control, but in a stand-alone pedal I don't know what would be acceptable. I've thought about Morleys but have never tried one. Right now I have a CEM chip based VCA I built which I control via pedal and it is beautiful; the only problem is that the VCA is part of a clunky older thang I built some time ago and wish I just had the VCA in a little box; don't know whether to build a new one, or find an "active" pedal. Does anyone have a recommendation? "Passive" pedals are simply out of the question, in my experience....
