Whether to get a TCI guitar, depends on the sound you want. I don't think folks understand what TCI is. The pickups in a TCI circuit and a non-TCI circuit are the same pickups. They will sound the same...until you apply the rest of the circuit. I'll explain.
Every guitar already has some inductance, resistance and capacitance in it. We are used to capacitors added to the pickups since the bumblebee caps in LP's, and after the DGT, we are used to resistors being added. What we don't see are inductors. That is because the inductance is already present in the windings of the pickups. So all of the components of an LRC (Inductance, Resistance, Capacitance) circuit are present in the guitar's electrical stuff. What is new in TCI is that PRS is applying the electrical concepts to pickups to affect the tone of the guitar. There is nothing magic about TCI. In the electronics world we have been designing LRC circuits for many years. We have been "tuning" circuits to a frequency since the beginning. Applying the concept to pickups is the new part that PRS has done. It allows them to "tune" the response of the pickups to a set of frequencies they want to emphasize. The result will be pickups that favor some frequencies at the expense of others. The result is a guitar tone that you might love, hate, or not really hear a difference. It all depends on what you like to hear, or maybe the frequencies your ear can or can't hear. The thing is, you are hearing what PRS thinks is a superior set of frequencies. That may or may not be what YOU think is a superior set of frequencies.
