I look at tone and gear as if I am a full-time musician. I spend top dollar to get the absolute best of all gear. I spend tons of time working on music. However, I am not a professional musician anymore. I am a husband, father and professional. My "true" needs are therefore somewhat different than my "aspirational" needs. I need a simple interface (all important controls easily gotten to), small footprint (small box that is fully functional without a footcontroller), as cheap as I can get, getting as good a tone as possible as fast as possible; all while not sacrificing tone and feel. After tons of A/B back and forth and going nuts, I realized the strengths of the KPA seemed more in line with my needs.
Talk to me next week and it will be different. I hope that none of this is taken as a knock against either of the products. The fact that the decision was so hard is testament to what a truly sensational job these companies have done.
