A special Pinch Mike has been designed for this piece and is available from Newsense Intermedium** (a good all around double bass mic). For long cable runs, a hi-z to lo-z transformer (Radio Shack 274-017) should be used with a balanced cable (preferable in any case). Output from the mic should be sent in mono to 2 large speakers to create a wall of sound for the performance (*see note below). If a delay box is used (preferrable), use a delay of about .063ms on the left channel. An indication in the program notes about the piece being a loud may be in order.
