Speaker - Jensen® Vintage Ceramic, 12", C12K-2, 100W, 8 Ω
The C12K-2 is a step forward from the C12K. It has a different cone membrane which grants a more extended treble response to increase the detail and the shimmer of the tone, yet retains a well contoured smoothness. Equally at home with clean and mid-gain crunch tones, the C12K-2 offers an outstanding response to the player’s touch. When used with higher gain tones, it offers a powerful, rounded, organic tone that delivers a full-bodied thickness to single note lead runs.
- Lows: Tight
- Mids: Warm
- Highs: Smooth
- Overdrive: Creamy
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.
Bassist Description: Not recommended for bass.
