How good does the SM57 sound on your voice?
Those it suits, tend to do particulary well with;
1) Shure SM7 (or SM7b)
2) Beyer M88TG (or less rugged M88)
3) Sennheiser 421
(Per posts at rec.audio.pro)
These comments also seem to hold true for myself, as the M88 and 421 have given me good results IMHO. Haven't tried the SM7 yet. Well known gear pundit Fletcher has referred to it as the
"hi-fi" version of the SM57-which he also thinks highly of.
Given you're in Europe, the Beyer and the Sennheiser could work
out well for you. Getting a nice used one will save more $$ too.
You can pick up
a M88 for around a third less $$ than a 441.
The M88 and 441 will demand more mike technique from you,
as the response pattern is much tighter than a SM57 or 421.
That's why I keep some more forgiving mikes around for when a singer wants to move while performing!
Best of luck on your selections,
Chris
P.S. If your voice is in anyway sibilant avoid the 421 MKII.
(brighter than previous models)
