The USA Player Series Cub 15R preserves the purity of the original Cub circuit while offering increased flexibility. This improved design offers the ability to select between a 12AX7 or EF86 pre-amp tube using the mini toggle on the faceplate or the included footswitch. This new feature offers far more gain and versatility than previous Cub models.
We also added a selectable tone stack boost in both modes to give this pure single channel amp four unique gain stages. It can achieve everything from the traditional Cub 12AX7 chime to complex EF86 gain tones that were unachievable on earlier versions of the Cub.
A two button footswitch to select the EF86 or 12AX7 pre-amp tube and engage the boost is included.
K Master® Patent Pending
The K Master® circuit is a completely original approach to power amp management which simultaneously controls current, voltage, gain, harmonic clipping and signal amplitude at intricate variables at the turn of one knob. This groundbreaking analog circuitry can achieve any amount of gain at any desirable volume while keeping tone and touch response 100% intact. The K Master also allows the power tube section to achieve something never before possible. When turned beyond 2 o'clock on the dial it begins to push the power section into harmonic saturation independent of the where the preamp gain is set. Combine this function with the pre-amp set sparkling clean to achieve big clean tones that ooze with rich power tube harmonics.
We discovered a unique way to make our reverb sit perfectly in the mix without ever overpowering the instrument or stealing tone from the preamp. This approach produces studio grade reverb right through your loudspeaker.
