Speaker - Jensen® Vintage Ceramic, 12", C12K, 100W
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
