About Peavey 20 Micro Head Amplifier

The Peavey Classic 20 Micro Head Tube Guitar Amplifier is a compact powerhouse, revered by musicians across genres such as blues, country, and rock for its ability to effortlessly navigate the tonal spectrum from vintage warmth to modern clarity. This all-tube amplifier delivers a robust 20 watts RMS, driven by a duo of EL34 power tubes and a trio of 12Ax7/ECC83 preamp tubes, ensuring rich harmonic overtones and dynamic responsiveness.

Crafted with meticulous attention to detail, the Classic 20 MH boasts two channels that emulate the revered gain structure and voicing of the iconic Peavey Classic series amplifiers. This design choice guarantees a pure and versatile tone that can be tailored to a wide array of musical styles. Both channels benefit from a shared three-band EQ, allowing for precise tonal shaping, while the built-in lush reverb adds depth and ambiance to your sound.

For players who love to integrate external effects, the amplifier includes an effects loop that maintains signal integrity and tonal purity. Additionally, both the channels and the effects loop, along with the reverb, are foot switchable, providing on-the-fly adaptability during live performances or recording sessions.

Peavey's innovative TSI (Tube Status Indication) technology is a standout feature, offering real-time monitoring of the power tubes' condition. This system not only alerts players to the operational status of the tubes but also pinpoints which tube requires replacement if issues arise, ensuring uninterrupted performance and ease of maintenance.

The rear panel of the Classic 20 MH is thoughtfully designed for versatility, particularly in studio settings. It features a Microphone Simulated Direct Interface (MSDI) with an XLR output, allowing for direct recording or PA system integration without the need for a microphone. The USB output further expands recording capabilities, providing a direct digital connection to a computer or recording device. A speaker defeat switch and a three-position power attenuator switch offer additional control over the output level, making it easy to achieve the perfect tone at any volume.

In summary, the Peavey Classic 20 Micro Head Tube Guitar Amplifier is an exceptional choice for guitarists seeking the soulful character of a classic tube amp with the convenience of modern features, all housed in a portable and studio-friendly package.
