    Comments about Boss MD-500 Modulation Effects Pedal:

    The chorus/dimension algorithms are worth the price alone. CE-1 setting sounds amazing as well as the others. Phaser sounds as good as any stand alone and does more. Univibe gets 95% of the way there to my favorite vibe! Overtone can get some great octaver style sounds. Tremolo does everything a good trem needs to do. Honestly all the effects are top notch and the sound quality is the best I've heard yet out of a multi mod pedal. My only complaints come in the flanger department. There is technically only one setting for guitar. All the other effects types have multiple algorithms. They seem to have gotten lazy on flanger and just put a jet plane style flange on there. I personally am not a fan of it. Hopefully they add a few extra algorithms such as thru-zero and a mistresss setting(my personal favorite flanger). A bit crusher would be cool as well but you can get some pseudo crusher stuff with the ring mod. If they cold just spruce up the flanger department then this unit would be absolutely unstoppable!!!!!
