Hi,
  I've been looping a ghanaian earthenware 
  pot, a 14" djenmbe and a dried bean shaker recently and despite the fact that 
  they vary greatly in volume, (the djembe is molto fortissimo) I use the 
  same mic on a boom stand for the lot to good effect. I just 
  move the mic closer to the pot than the big drum. So i'd reccommend 
  getting a physically small mixer like a soundcraft spirit witht nice quiet pre 
  amps in it, (You only need a couple of effects sends). Try your rig using one 
  mic and if it don't work buy another! Just being able to swing the mic out of 
  the way is nice and simple for me I dont want mic stands all over the place. 
  Also if your getting feedback you know which mic it is 'cause there's 
  only one. I've got my mic on a footswitch plugged into an insert so I can 
  knock it off too. Do what you suggest below in terms of the patching of the 
  system. Adding effects though - well -experiment!

  Goal:  Accompany live house dj(vinyl) 
  with following abilities:  either one mic used for different 
  hand drums, or multiple mics respectively, ability to add effects to drums, 
  have multiple loop samples playing simultaneously, manipulate effects 
  which are on existing loops, piping all output through dj's mixer 
  so he/she can manipulate the hand drum's presence.   
  
      My research has brought me to the JamMan, 
  Boomerang, and the Echoplex.  My main concern is that this is all going 
  to be happening extremely fast and live, and with percussion vs. 
  guitars.  Is there one more suitable?  Know of any available 
  JamMan's(sorry, had to ask=)?
  Additionally, I am a little uncertain as to the most 
  efficient way to set the connections to best facilitate me.  Must I run 
  from mic to mixer to Looping device via Aux Send then back to Mixer 
  channels?(then into dj's mixer) When is the best time to add effects? 
  
      I'm getting mixed messages from people I 
  consult as most are unsure;  others are trying to sell me 
  extremely expensive mixers with multiple Aux Send ports I'm not sure are 
  necessary.  I have and will continue to read archived info, but need to 
  take some important first steps.
      I sincerely appreciate any 
  guidance/direction you may provide-
   
      Take care, Saybolt
