I need to decide which of the two effects buy and each of them speaks to me from a different perspective. I love the compact size of MS60B but how easy is to operate the effects on the fly with only 1 screen ? Does the MS60B lack any significant effect from the B3 model ? Is the effect quality better in any of those models ? Are there any other disadvantages or problems related to the smaller zoom, which should I know of ? At the moment I'm leaning toward the MS-60B, as it fits my pedalboard better and I dont care too much about drum machine, the only thing that hold's me back is that B3 seems easier to operate with separate LCDs and has twice the effects.
