I consider this pedal a budget Carbon Copy. This is definitely not a bad thing though - I've always thought the MXR was a bit overpriced. It has a pretty much identical feature set - blend, delay time and feedback, as well as switchable modulation. Straight out of the box the modulation is a bit goofy - you'll need to open up the pedal and adjust the internal trimpot for depth. It's a shame there isn't a trimpot for rate either, but if you NEED more control over the modulation the Memory Boy, also by EHX, would suit you better. It's a bit annoying that you have to remove the back of the pedal to adjust the modulation but it only takes a few minutes. The delay time offered is very short, but I wouldn't say it was a draw back. With this kind of analogue delay you're probably wanting to thicken up your sound a bit, which doesn't require more than a few hundred milliseconds. It's easy to get this pedal to self oscillate if noise-making is your thing though, in my opinion, self-oscillation starts too early on the feedback dial. There was no massive flaw with this pedal, but ultimately it didn't suit my amp, which is already a bit dark - the delay just sounded like mud.
