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

This speaker will be a good fit for a Peavey Bandit.Be sure to match your speaker impedance correctly.

This would be a nice change if you are looking for something different. These speakers will be voiced with more of an American flavor as compared to the typical British style of speakers. For more information please see the Jensen Tone Generator: https://www.jensentone.com/tone_generator
