I've been using the Digitech RP300 for nearly 3 years now. It is an awesome piece of equipment. I'd definately recommend getting it over a delay pedal here or a wah pedal there. This does it all and it's got a real low learning curve. It's got 40 built in effects and room for 40 more customized effects. One of the cooler things is that on digitechs website you can check out the various patch libraries and customize your own effects without having to figure out what all the different things mean.
