i've been using a heil pr 40 on my ampegs for the past couple years. but earlier this week, i was actually given an ev re 20 by an old friend of mine from canada who shall remain nameless unless he wants to identify himself, but he shall be referred to in this thread as "the greatest person to ever live." so i got to my gig early today and asked the soundman if he didn't mind letting me ab each mic before the gig. so i finally got to compare the re 20 and the pr 40 in the same setting. the pr 40 is often compared to the re 20, and they both sounded excellent, but there are some differences. pr 40: ---big low end and midbass, upper mid presence but not quite as present as the re 20 ---snappy high end but not much past 10k ---hot re 20: ---more even response ---snappy high end, not quite as hyped around 3-5k as the pr40, but has more ultra-highs ---hot enough, but needs to be boosted compared to the pr 40 the soundman clearly preferred the re 20, so that's what we ran with. i liked both and thought both had compelling reasons to use them, but i thought i'd give him a chance to make it shine in a mix. i went offstage a couple times, and i liked it a lot in a mix. though i do like the midbass from the pr 40, i think the re 20 sounded a little more natural and more like the amp itself. you could eq them to sound more similar, i'm sure, but the re 20 may work a little better for my thing. of course, this is the first gig i've used it, and i really haven't gotten to know its character at the level of the pr 40, but i plan on doing some recording with it and the pr 40 this weekend. i'll post some clips and see what you all think, but if it goes the way it went on the gig tonight, i may be switching permanently.
