I've owned the rp50 for... 6 years? I found the distortion to be lacking (a lot!), since I play mostly metal. It did have some very usable chorus/ delay/ reverb/ clean sounds however. Great bang for your buck if your looking for any of those. Just make sure you don't crank it or you get a TON of digital clipping haha.

EDIT: if you're looking to play blues, than a, expression pedal will open up tons of options for you. volume swells, whammy, wah effects. but unless you think you will use those extensively, dont just buy for the expression pedal.
