    The Classic Pro R is the 6L6 powered amplifier Bad Cat enthusiasts have been begging us to build for years. This blackface beauty is the latest addition to the USA Player Series.

    This Classic Pro is expertly hand-built by our team in our Southern California shop using the same components and materials as our point-to-point Legacy Series amps.

    Incorporating Bad Cat’s patented K Master circuit the amplifier offers big headroom, beautiful string to string note definition, incredible smooth break-up and rich harmonics. The American style punch and sparkle is here and yet we don’t comprise the Bad Cat signature sound.

    Dual K Master volumes that can be selected via foot switch allows individually controllable rhythm and solo levels.


    Single channel American voiced amp with reverb, passive FX loop, and two foot-switchable K Master volumes for rhythm/lead output levels. The amp will ship with 6L6’s for 30 watts of power but the amp will run at 16 watts with 6V6 tubes with a bias adjustment.


    Classic American tone first introduced during the mid 60’s with the added headroom and refined response offered by custom hand wound transformers, premium components and short signal paths. Sparkling cleans with the ability to drive into smooth , harmonic rich overdrive. The patented K master circuit allows every tone the amp can produce at any volume level without compromise.  Adjustments to the bias circuitry allows the amplifier to operate on 6L6 or 6V6 power tubes.


    Combo: Signature Bad Cat aesthetics include black tolex upholstery over 11 ply Baltic birch finger-joined cabinetry, gloss powder-coated black metal corners, silver sparkle piping, variegated silver sparkle grill cloth, hand stitched heavy leather handle, black phenolic chicken head knobs, backlit Bad Cat logo, and Bad Cat’s proprietary UK-made Celestion speaker.
