The Vibro King. Here's what Jensen say about the C10Q: Straightforward tone with mid-frequency bite. Presented with overdrive distortion, it can sound edgy. Lows Mids Highs Overdrive Loose Aggressive Bright Edgy Adopted primarily in the Vibrolux® and Vibroverb® amps of the Brownface and Blackface era, the C10Q is a very easy to drive speaker that breaks up nicely with straightforward biting character. It was also very common in many Silvertone® and Valco® amps. It loves the 2x10 configuration and the floating baffles.
