a
technology
company
committed

in
2001,
both
end

and
reviewers
acclaimed
the
build
and
sound
quality
as
nothing
short
of
amazing.
Pushing
the
“Price
Vs.
Performance”
envelope
even
further
,
we
brought
out
the
“B”
Series
mics
in
2002.
As
part
of
the
“B”
series
we
introduced
our
first
electronics
product,
the
highly
acclaimed
VTB1
Mic
Pre/
Direct
Box.
Now
we
of
fer
our
second
release

what
will
be
a
