Dunlop EP103 Echoplex Delaychat_bubble_outlineFrom real comments

The tone is widely praised as warm, clean, and true to the original Echoplex EP-3. Multiple commenters call it the cleanest, warmest delay they've tried, noting it doesn't mess with or color their core tone. Several say it's very close to a real vintage Echoplex EP-3 in blind tests, and prefer it over pedals like Carbon Copy or Canyon that they feel harm the high end. Tap tempo is called a lifesaver for rhythmic playing, extending delay up to 4 seconds with an external switch.

Power requirements are a recurring headache for users integrating it into a pedalboard. The EP103 needs 9V at 250-300mA rather than the more common 100mA, which trips up owners using standard multi-pedal power supplies like Voodoo Lab or shared power bricks, sometimes causing high-pitched noise, blinking lights, or no power at all. Users had to specifically seek out compatible high-current outputs, and one spent an hour troubleshooting before finding the fix documented in forums.

Build quality and design choices draw mixed reactions despite the good sound. Some owners feel the knobs and casing feel cheap for the price, and one reports the footswitch makes a loud audible boom through the amp roughly one in ten presses. The AC adapter jack placement on the side below the input, instead of the front like most pedals, is called poor design by more than one commenter. A few also wish for a tone control, adjustable output level, or a built-in switchable preamp.
