Tips: * Where is the best place to stick the mics ? Depends on what instrument you are trying to mic. Most instruments the best placement will be directly underneath the saddle/bridge. * What is the little square plastic piece for ? You can thread the wire tie thru it in place, then stick the square out of the way and secure the excess cable to it. * How to use the Self-adhesive ? Remove the plastic film from the back of the transducer to expose the adhesive. Features: 1. Through Cable Hole:7 x 3mm/0.28" x 0.12"(L*W) 2. Endpin Jack Length:6.2cm/2.44" 3.
