Catalinbread Echorec: an amazing, versatile delay pedal that really nails that tape delay sound, and also has a hidden gain trimpot that can turn it into a deadly fuzz. Perfect working condition. Very little sign of wear on the front, but there is velcro on the bottom. $200

TC Electronic Alter Ego Delay: also a very cool-sounding delay pedal with a lot of options, downloadable TonePrint settings, and some really handy internal switching options (buffered with tails, true bypass, and all-wet). It can run in stereo, which, when placed in the "all wet" setting, is great on your fx bus in a mixing session.
