Classic Pro 20R USA Player Series 20W 1x12 Guitar Combo Amp

The Classic Pro R is the 6V6 / 6L6 powered amplifier Bad Cat enthusiasts have been requesting for years. This blackface beauty has that vintage California tone first introduced during the mid '60s with the added headroom and refined response offered by the company's custom hand-wound transformers, premium components and improved signal paths. 

The Classic Pro amplifier offers big headroom, beautiful string-to-string note definition, incredibly smooth break-up and musically rich harmonics. This plethora of American tones can cover everything from big cleans to smooth breakup and the company's patented K-Master circuit allows every possible tone to be produced at any volume level desired. The Classic Pro features dual K-Master controls that can be selected via the included footswitch to choose between rhythm and solo levels. This amp ships with 6V6s for 20 watts of power, but will run at 35 watts with 6L6 tubes and a quick bias adjustment.

Reverb 
Bad Cat uses a unique way to make the 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. 

Daul Patented K Master
The K Master is the first true innovation in master volume technology in years. Players who have experienced it know that power amp gain is different than pre-amp gain. It feels and sounds different. Often time what players associate with “power amp” distortion is really the sound of the phase inverter tube getting crushed by the output of the preamp section. To this point, master volumes have always been passive attenuators. Until now, most master volumes were unable to do anything but attenuate before or after the phase inverter tube. The drive to the power section after the phase inverter was always dependent on the drive coming from the pre-amp.

The K Master works differently. The master works as an independent amplifier circuit which sits post phase inverter, independently controlling the power to the power tubes while keeping the tone and sound of the preamp even as it overdrives the phase inverter intact. 

Foot switch between two K Master volumes. One for Rhythm and one for lead. 

The K Master patented technology has allowed Bad Cat to re-invent the concept of the master volume and make amps that are built for stage use, useful for bedroom applications.

This amazing amplifier covers everything from clean sparkle to harmonically rich saturation and is available in a head or 112 combo. Experience why Bad Cat amps are played by some of the biggest artists on some of the largest stages in the world. 

What is the difference between Bad Cat's USA Player Series and its Legacy Series amps? 
Both are hand built in Bad Cat's California shop by its experienced crew using the same chassis, components and transformers. Components on the Legacy amps are connected with meticulous point-to-point solder joints. Identical components on the USA Player Series amps are through-hole mounted on a military-grade circuit board. Still constructed by hand, the PCB construction offers time savings, build consistency and the ability to isolate grounding planes for reduced noise. This method of construction requires a different style of jacks, potentiometers and tube sockets, but no expense is spared. Bad Cat uses Cliff jacks, premium-grade sealed pots and shock-mounted ceramic tube sockets to maintain the same level of quality as the Legacy Series. All Bad Cat amps are housed in the same finger-joined cabinetry and combos are equipped with the proprietary Bad Cat UK Celestion speaker.
