Figured I would ask, as I have been GASing for both for quite some time. Christmas is on the horizon, so I figured why not. I've been leaning towards the MD500, as I already have several delay pedals and haven't even tapped into the full potential of my Alter Ego X4 yet. Figured I can clean my main board up a tad and make a little room if I add the MD500 to handle all my modulation needs. Guess I am asking if anyone has one or played around with one long enough to have a well informed opinion on whether either pedal are worth the investment. I keep backing out every time I'm about to pull the trigger. Reason being is that I am also GASing for the new TCE Quintessence and the Keeley 4 Knob Compressor. Figured I can get both of those and save a little, or break bad and get one of the Boss pedals. Any thought. I need to let Santa know something soon.
