I just dug out my old digital delay pedal (it was a birthday present when I was about 15). It wasn't working any more so I took it apart to look for any loose solder joints. Couldn't find anything, but I gave it a general clean-out and now it miraculously works fine, though the switch requires a good hearty stomp to activate - might see if I can do something about that.
Now that I've played about a million delay units, I appreciate this one a lot more. It doesn't sound as warm as my MXR Carbon Copy, but it's a little soft around the edges compared to a Boss digital delay. The repeats sound slightly smoothed over, and when used with a good power supply it's very quiet.
Delay time is only 400ms, but that can be tweaked with a simple mod. Construction feels a little flimsy, and battery life is remarkably short, but despite these little niggles, I still really like it, and I've made a permanent place for it on my pedal board. I might put it in a true bypass loop just in case the switch gives me any further trouble.
