The TC series of pickups provide a really good sounding pickup that can be mounted quickly and easily to Tricone instruments without having to drill any holes for anything when installing the TC Std or TC Pro passive versions. The TC's in passive format are available with your choice of either an endpin jack or one of two jack assemblies (one with a volume control) - both of which simply adhere to the instrument and snuggle in right next to to the tailpiece. The MVC jack assemblies give you a much more secure and reliable mounting for an output jack assembly than anything that clamps to the side of the instrument. These jack assemblies, which nestle in right next to the tail piece, are only a half an inch high. For those players who want an on board preamp, the TC-A is the active version in the lineup and combines the TC sensor with our Artist II endpin jack preamp that may be run from phantom power - so no battery need be installed.
