Morgan AC20

The Morgan AC20 is a highly regarded boutique amplifier known for its exceptional tonal versatility, vintage-inspired design, and ability to handle both studio and stage applications. Below is a synopsis of its history, popular settings, and notable players.

History of the Morgan AC20

• Introduction (2009): The Morgan AC20 was introduced by Joe Morgan, founder of Morgan Amplification, as part of his mission to create amps that blend vintage British tones with modern functionality. Inspired by the Vox AC30 but tailored for more manageable wattage and improved usability, the AC20 quickly gained a reputation for delivering rich, chimey tones characteristic of early '60s Class A EL84-driven amplifiers.
• Evolution: Over time, the AC20 evolved into the AC20 Deluxe, offering additional features such as switchable preamp tubes (EF86 or 12AX7), Normal or Brilliant channel voicing, and a Power Level control that allows players to adjust output from ¼ watt to 20 watts without sacrificing tone. This made it one of the most versatile amps in its class, appealing to guitarists seeking classic tones at practical volume levels.
• Design Features: The AC20 is hand-wired in the USA and features a simple yet powerful single-channel design with extreme touch sensitivity. Its Power Level control ensures optimal interaction with pedals, while switches for Brightness and Treble Cut allow further tonal shaping. The amp's compatibility with modulation pedals like reverb and delay adds to its appeal for pedalboard-focused players.
• Legacy: The AC20 has become one of Morgan Amplification's best-selling models, praised for its ability to deliver vintage Vox-inspired tones without the "ice-pick" harshness often associated with those designs. It remains a favorite among professional musicians across genres.
