Looking to grab a second delay pedal, one with tap tempo and longer delay times. I have a Keeley Mag Echo (actually i have the Caverns Delay/Reverb whose delay side is the mag echo). Its a great delay, i love how it stays out of the way if you want it to and creates a nice atmosphere and sense of space. Im looking at the Echoplex EP103 for its tap tempo and long delay times. However, if its just too similar to the Mag Echo, I'm looking at the Walrus ARP 87 for something a little different. So, EP103, redundant or a nice addition to the Mag Echo?
