And also one of its downsides. You are playing something, you want a chorus, ok, you have 10 choruses, with a load of settings for each one. You get a sound you like, maybe one of the other choruses is better? lets try the next one, and fiddle with the settings. No maybe the next one is better. hmm maybe the first one was better at this settings.. oh hang on, I have run out of practicing time.
