Description

The Soldano ASTRO-20 3-Channel 20-Watt 1x12" Guitar Combo is where vintage tube tone meets modern technology. Engineered by Mike Soldano, this amp is a sonic powerhouse, boasting three versatile channels—Clean, Overdrive 1, and Overdrive 2—each offering a tapestry of tonal possibilities. What sets the ASTRO-20 apart is its 4-Galaxy system, allowing you to assign unique tonal characters to your sound: Green for high-headroom cleans, Blue for bluesy crunch, Purple for tight high-gain, and Red for classic Soldano leads. Whether you're performing live, recording in the studio, or practicing at home, this amp adapts seamlessly with its cab-free operation powered by a built-in IR loader.

The ASTRO-20 is equipped with a Celestion G12M Greenback speaker, delivering a broad mid-range attack and controlled low end, providing the depth and richness you crave. And with a powerful digital engine featuring an oversized 500MHz ARM DSP processor, the amp boasts low-latency impulse response for an authentic tone without the need for a speaker cab. Its intuitive front-panel controls and free Soldano Editor Software allow you to easily save, recall, and organize your presets, making it a dream for gigging guitarists.

Critic Reviews

“More than enough firepower to keep up with a heavy-fisted drummer…” The high-tech, hard-rocking Soldano Astro-20 amp reviewed | GuitarPlayer

guitarplayer.com

The Soldano ASTRO-20 3-Channel 20-Watt amp is a versatile powerhouse that impresses with its blend of classic high-gain tones and modern features. With MIDI-switching and IR capabilities, it's a future-proof choice for both stage and studio. However, the clean channel might feel a bit sterile, and the lack of control gradations can be a minor annoyance. Overall, it's a fiery, adaptable amp that deserves its Editors’ Pick award, especially for those seeking a robust yet compact tube amp with a rich Soldano heritage.
