I am thinking to get an envelope filter. My No "1" choice would be 3Leaf Wonderlove but according to its price (especially here in Europe) and the fact that I am going to use the filter just for a subtle coloration, I will probably never get it. The No 2 choice would be the ehx qtron plus. I can stand its extra power supply but I don't know how big this is (and I searched a lot for this info). So could an owner of the qtron plus tell me about its dimensions?? (and his comments of course!!) Thank you very much!!!
