H'okay. Tavo sought to recreate the RE-301 pre-amp thingy in his pedal, thus we owners can that old space echo Setzer pre-amp sound, without the tape unit. Very handy. The Boss RE-20 space echo is supposed to be a digital version of the RE-201. Does this mean it is running same pre-amp chip? Or emulating it? If so, do this mean I am pre-amping my signal twice?
