Bad Cat Classic Pro 20 Reverb USA Player Series 20W Valve Guitar Amp Head

Written by

Bad Cat have been making professional-level, hand-wired, boutique amps in the USA since 2000, earning a reputation for excellent build-quality and an organic valve-driven tone. The Classic Pro 20 Reverb head is no exception, combining pristine US 6L6 tones with just the right amount of premium tonal flexibility.


The lovingly hand-built Classic Pro R is a 6L6-powered amp that forms part of Bad Cat’s USA Player Series. It offers that timeless Blackface resonance that helped define the electric guitar sound. The dual K Master volumes are footswitchable, letting you individually control your rhythm and solo levels.

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 by the bucketload - without comprising the Bad Cat signature sound.


Part of what makes Bad Cat amps so great is their ability to combine classic, sought-after valve tones with flexible functionality. The single-channel Classic Pro 20 features a passive FX loop, a solid-state rectifier, digital reverb, and of course Bad Cat’s signature K master volumes.

The K Master circuit gives you unique control over a number of parameters with a single control – and is all analog. Tweak current, voltage, gain, harmonic clipping and signal amplitude with one knob, providing all the gain and dynamics you need at any volume.
