21. The Distortion Generator includes compression, distortion and cabinet simulation circuitry . 22. The metal tab is often connected electrically to the internal circuitry . 23. Modern encoder systems employ circuitry to trim these error mechanisms automatically. 24. The sidetone audio is typically derived from the transmit audio circuitry . 25. They have control circuitry like that found in the silver torcs. 26. This method allows great precision in determining the thickness of circuitry . 27. A great deal of logic was given over to diagnostic circuitry . 28. Their short axonal parts contact thalamocortical or other local circuitry neurons. 29. As of 2016, most development effort is for electronic circuitry . 30. When handling electrical circuitry a spark can sometimes affect the circuitry.
