The sky’s the limit with the Soldano Astro-20, a three-channel, four-Galaxy 1x12 combo delivering all-tube tone that’s out of this world. This American-made, 20-watt combo features a Clean and two Overdrive channels, powered by two 6V6 power tubes and four 12AX7 preamp tubes. Along with six DSP-powered IR slots to choose from, the Astro-20 is packed with four distinct Galaxies, giving you even more style-specific tones to explore. Whether you’re looking to stay grounded with traditional sounds or blast off into uncharted sonic territories, this combo is perfect for guitarists who want classic tube tone with modern flexibility. Equipped with a Celestion G12M Greenback speaker, the Astro-20 is an ideal standalone option for live performance, rehearsal and studio recording.

Galaxies of Tone

Along with three channels of all-tube awesomeness, the Astro-20 is loaded with four selectable Galaxies to add even more flavor to your riffs. The Green Galaxy is featured on the Clean channel and ranges from crystal clean to slightly pushed crunch. Blue, Purple and Red offer increasing levels of overdriven breakup from one to the next and can each be independently assigned to the Overdrive channels. They can then be further manipulated with separate Volume and Gain settings on each, allowing you to continue expanding your musical universe with virtually endless combinations of colorful soundscapes.

Assignable Impulse Responses

IR cab simulation is an essential tool for today’s guitarist, and the Astro-20 offers six to choose from. Each expertly recorded IR can be assigned to a channel or Galaxy independently, ensuring you get the ideal tone and speaker response you’re looking for, whether it’s onstage, recording or utilizing the headphone output for silent practice. You can also add and manage your own IRs using the included Soldano Editor software. The Soldano Editor Software features an intuitive user interface, allowing you to easily assign Galaxies to the Overdrive channels, select different IRs for all three channels, load and organize your IR library, and save up to 128 MIDI presets.

Classic All-Tube Tone

Even with versatile onboard controls, the Astro-20 features inimitable analog charm with two 6V6 power tubes and four 12AX7 preamp tubes. The warm, rich sound—synonymous with rock, country and blues—is instantly recognizable. But with tons of tone-tweaking features, this 20-watt combo gives you everything you need to sculpt that classic tone into something entirely unique. The Astro-20 is even suitable for cab-less operation, allowing users to safely go to front of house, a recording device or headphones without connecting to a speaker cabinet.

The sonic possibilities are virtually endless with the Astro-20 combo amp. Four distinct Galaxies across three channels provide nearly unlimited customization options, so you can find the perfect tube tone you didn’t even know you’d been looking for. With Soldano Editor software, convenient STAR Display and a four-button MIDI footswitch included, the Astro-20 lets you save and access any combination of channels, Galaxies and onboard IRs with ease.
