Sound — 9
I use the RP50 with a Crate GT65 amp and a Stratocaster. The only noisy setting is number 40, a very loud distortion/overdrive. It makes great delay, flange, distortion, and chorus. One thing I really like about it is that one of the settings it comes with sounds just like what Jimi Hendrix used live for Purple Haze.
Overall Impression — 9
I really like it over all, it can make about any effect you can think of and at $75, it costs about the same as a single effect pedal. It is really worth the money when you think about how much you save in the long run because you dont have to buy effects. I am satisfied with it 100% and recommend it to anyone that has a little natural talent with these processors.
Reliability & Durability — 9
It is very dependable, but takes up a whole nother outlet, not batteries. That is the only thing I can think of that would play against it's reliability, otherwise its great!
Ease of Use — 6
The effects that it comes with are really wild, all of them are different and it is fun to play with. All of the pedal effects you own can be found in this (except a great wah). If you are wanting to go ahead and make your own effects, be prepared to spend some time and frustration, it is difficult. The manual clears up a few problems, but doesn't explain well how to make new effects.
