I am right on the edge of buying a VMP-4000E. I was hoping to find a set of pres with a nice mix between transparency and controlled coloration. Based on what I have read here, it appears as if Sebatron would meet my criteria quite nicely. Because these are valve based pres I was also wondering about their suitability on quieter instruments where higher gain settings are sometime necessary. It seems as if everyone in this forum has nothing but praise for these mic pres, I was wondering if anyone had ANY feedback about when these pre's might NOT be ideal - thanks.
