In my continuing quest to be a big fish in a small pond, tone wise, I'm caught between getting a Tech 21 SansAmp Bass Driver or an Aphex 104 Aural Exciter Type C2 or something that maybe you can clue me into. I've not had the pleasure to use either unit. I saw a warm-up band at a Special EFX concert years ago and the bassist was using something that made his bass sound glassy, crystal clear and ringing without harshness or treble or taking ;the balls out of his bass. I've since concluded he was using the Aural Exciter, (just a guess really). But his effect was almost "trippy," as if the bass was in the seat next to me. On the other hand, I've heard good things about the Tech 21 SansAmp Bass Driver. It costs about the same as the Aphex from what I find, about $180. I would like something that will help add some authority to the B on my 5 string and will take some of the airyness, wimpiness, thinness, out of my D and G, (I'm using .045-.125 DR "Marcus/Fat Beams" . My E and A are just great). Any input is most appreciated. I'm trying to stay under $300.
