Need Looping Microphone Advice!

[Drumworker <Drumworker@aol.com>]

OK, so here's what I'm trying to do.

I'm developing a piece for steel pan (steel drum) primarily using a series 
of
loop cycles in a number of contrasting sections interspersed with a couple 
of
"long tone" - cadenza type passages. I am currently using an overhead mic
input into a JamMan > passed through an effects processor (to produce a 
stereo
signal and generally "fatten" the sound) > out to the PA.  A very
knowledgeable friend has suggested that I use a Sennheiser 421 to mic the 
pan
but I'm not sure its giving me a good frequency response from the  
distance of
15" or so. The output produced sounds rather subdued - not the brilliance 
that
is characteristic of a good steel pan.

Can anyone suggest a better mic, still fairly directional - so that other
ambient sounds aren't easily captured in the loop, but will give me a wider
spectrum, particularly in the top end??

This piece will be recorded for broadcast on national radio (in Canada) and
needs to sound as good as possible. Plus, I find that I'm really getting 
into
the "loop thing" and if I can get good results from this project then I'll
probably become a looper for life.

As usual, any suggestions are greatly appreciated.
