I set aside some time to read the manual and tweak the parameters and loved the results. There is a slight learning curve ---- it's a little more complicated than a standard single effects pedal with three or four knobs. But that is the price for the versatility it offers. Originally I was going to buy a phase shifter, a flanger, and chorus pedals ----- three pedals! But the cost of those three pedals would have been more than the cost of the Boss MD-200. With the MD-200 I was able to get a Flanger effect, a Phase Shifter effect, and a Chorus effect that I like very much ----- plus there are all the other effects I can play around with. The sound quality is great and the ability to use an Expression Pedal plugged into the MD-200 makes it even more of a bargain. It's found a place on my pedal board and I'm happy with the purchase.
