Acoustic Guitar:
Hamburg I - natural, even, full, nice highs - I like it.
Hamburg II - Unnatural, scooped mids, has an Ovation effect on the guitar - it sucks.
Vienna I - not as full as the Hamburg, less mids, more highs....at least you can hear more of the pick on the strings. Nice, but the Hamburg I is still better.
Vienna II - interesting, sounds processed....lively, odd mids, sort of like a metal bodied guitar, this might work well in a mix or as a compliment so something like the Hamburg I.
Overall I like the Hamburg I the best. It's the most natural and I;d best you could do the most with it regarding placement and EQ. The Hamburg II just sucked, period.
Clean Guitar:
Hamburg I - again..... full with easy on the ears highs, maybe a bit dull in the highs.
Hamburg II - better than on acoustic guitar, processed sounding, hollow mids, sounds like it might work well for Tele twang.
Vienna I - I like this the best, clearer than the Hamburg I and would probably sit best in a mix.
Vienna II - sounds EQ'd, very present and would be the best of the 4 for cutting through in a mix.
Overall I think I'd pick the Vienna I bcause I believe I could easily EQ it to sounds like the Vienna II but not vise-versa. I just don't seem to like the Hamburg II on guitar at all. It's tiny, tinny, hollow and small. Yuck!!!
Distorted Guitar
Hamburg I - sounds a tad muffled, maybe just off axis sounding. Not bad, not great
Hamburg II - hyper on axis, can really hear the speaker grind too much, I bet it might sound good a bit off axis, but as is, sounds like a speaker without being in a cabinet.
Vienna I - most natural, well balanced, good highs but can still feel a hiint of a brownishness. Would probably be the most versatile.
Vienna II - better than the Hamburg II as it has a tad more body but still too much speaker grind coming through.
Overall, it sounds like the II versions may be more open but that isn't working for the distorted guitar. Maybe if they were placed differently. I dunno, they seem to lack any body at all.
Female Vocal
Hamburg I - a bit of grit, a little blanketed in comparison, seemed to not handle being pushed hard.
Hamburg II - Ah....no we hear it shine a bit. Very clear, no grittiness, excellent highs that are sweet and not harsh. Sounded very good.
Vienna I - clearer than the Hamburg, still some grit, handled being pushed better, not as open and airy as the Hamburg II, which is better than either of the Is without a doubt.
Vienna II - extremely clear, too much so maybe, the highs were a tad hard on the ears.
Overall - the Hamburg II was the clear winner.
Male Vocals
First off.....these vocal lines are filled with esses and eches.
This could be good or bad depending on what you want to show.
Hamburg I - slightly veiled but even.
Hamburg II - Open and airy, the esses and eches are pushing it a bit....maybe sing a bit of axis.
Vienna I - similar to the hamburg I, but ironically a tad more veiled.
Vienna II -sibilance galore on this vocalist...ouch, it hurt. Whatever the other qualities were killed for me by the sibilance.
Overall, the II versions are obviously much more open and detailed on vocals. For this vocalist the sibilance was just way too much on the Vienna II and just about all I could take with the Hamburg II. I think it could easily be tamed with the Hamburg II, would require more work with the Vienna II and not sure if it would be worth it. In all, I'd again pick the Hamburg II first. With a different voice these mics could either be way better or way too harsh; however, I do think they show a much greater level of detail overall.
So there you have it.....a mixed bag......as would be expected.
They all have their qualities, just like any four different mics.
