the kk pure xlr is a great little pre that will
give excellent results . it has an eq that you
can tweak on the fly to help if the system
isn't up to snuff. it's a about the size of two
packs of 100s cigarettes. I find the kk pickups
alone did not work well at open mics, i use
a sunrise mag pup. i find it sounds pretty
good in whatever i plug it into. This versatility
works good for me.
why do you want to remove the mag pup?
just wondering why you don't want to leave it
in. ?Also you have a tonedexter. why not just
bring that to the open mic with whatever pup
you made the wavemaps with.?
obviously the mic will give you the best natural
sound. if the open mic is quiet like you say.
And it's the only one you plan on attending.
then the sm81 is a great choice. if you go to
a loud room noise open mic then the pup preamp tonedexter
would be a better choice.
