While not strictly a vintage reissue, the C12K is the first design that Jensen developed in the early ‘90s. It is tonally inspired by the classic vintage ceramic Jensen, but with a substantially stronger voice, full bass and smooth top end. The C12K became one of the speakers of choice for Fender®, used in a myriad of world-selling models. Vintage tone with modern power handling and dynamics are the key virtues of the C12K.

Guitarist Description: A real workhorse, heavy on the mids with a solid, straightforward tone. Presented with overdrive distortion it powers through with lows that are bold and heavy.

  • Lows: Tight
  • Mids: Aggressive
  • Highs: Subtle
  • Overdrive: Edgy/Crunchy
