I previously owned a Boss ME-50B, I bought it to find out what I wanted from an effects point of view, it gave me a chance to experiment with just about every effect on the market and not put myself in debt for life. Now that I know what I want, I am looking to buy a Boss Bass Equalizer, Distortion, Flanger and Bass Chorus because thats all I want, not 33 preset effects that don't have the flexibility and independent control such as individual pedals have.
Flicking between FX to get the right one on an FX board is a pain in the arse anyway, I want to be able to flick through whilst playing and not run have to hear Saw Lead while getting from Distortion to Chorus.
Don't get me wrong, FX boards are great for people that don't really know what they are looking for or that want to experiment with combined FX but nothing compares to having the real deal with no crap you don't want.
