IMO digitech and other inexpensive multi effects are more toys than useful devices. Be careful when you look at them, they can seem really cool in the store and then after a few weeks of having them you realize they are crap. I've had a couple of them over the years and have always traded them in. Stick with Boss/Roland and better and you will have effects that you keep forever. I really like the Fulltone Fulldrive for overdrive, Boss DD-3 and RV-3 for reverbs/delay (of course there are better if you want to spend more), Fulltone Choral Flange for chorus/flange, electro harmonix makes great pedals as well. It took me a long time to learn about quality effects so be careful!
