Re: Recommend me a good delay pedal
I used to swear by the DD-3 until I bought an Ibanez DE-7.
The DE-7 has fantastic digital but an even better and warmer sounding analog delay. I've heard it's not actually "analog" but that the approximation is extremely close. Regardless of that, the analog mode on that pedal is where it's at. Plus, the digital delay part has great clarity, isn't very metallic sounding (like the DD-3), and can be used for all kinds of cool quasi-looping effects.
Since your request for a delay is based on one song I'd say go for the Boss DD-3 but if you're looking for versitility and a better sounding delay down the road go for the Ibanez DE-7.
