The ASTRO-20 is a 3-channel, 4-Galaxy, assembled-in-USA 1×12” combo that combines authentic all-tube tone with features ideal for today’s modern guitarist. Mike Soldano designed this sonic powerhouse to be a fully featured versatile 20w guitar amplifier. The ASTRO-20 can also be used as a stand-alone cab-less amplifier ideal for live sound, rehearsal and studio recording sessions, thanks to the DSP powered IR cabinet simulation.
The simple front panel design of the ASTRO-20 lets you save any combination of the channels, Galaxies, and IRs and quickly recall them with the included 4-button MIDI footswitch. The free downloadable Soldano Editor Software makes organizing presets and integrating your own IRs fast and easy.
All-tube Tone
Despite its incredible onboard control, the ASTRO-20 is a straightforward, all-tube amplifier that is powered by two 6V6 power tubes and four 12AX7 pre-amp tubes. There are three channels to select: Clean, Overdrive 1 or Overdrive 2. The Clean/Green Galaxy is a high-headroom circuit reminiscent of classic American combo amps. It ranges from crystal clean to slightly pushed crunchy tones dialed in with a single Tone knob and a 3-way Bright switch. Overdrive 1 and Overdrive 2 include independent Volume and Gain with a shared 3-band EQ. The Blue, Purple, and Red Galaxies can be assigned independently to each of the Overdrive channels via the Galaxy select switch.
All features of the ASTRO-20 are controlled right from the front panel, making it convenient and versatile. The innovative STAR display indicates which Galaxy is being played (Green, Blue, Purple or Red), while the 6 “planets” around the star indicate the current IR preset. The planet indicator will turn OFF in CAB BYPASS mode.
A Universe of tone Cab Sim Onboard
Impulse response cabinet simulation is an essential tool for modern guitarists. The ASTRO-20 offers six onboard IR slots to choose from. Each expertly recorded IR can be assigned to each channel/galaxy independently, ensuring you get the perfect tone and speaker response, whether running direct onstage, recording, or utilizing the amp’s headphone output for silent at-home practice. Add and manage your own IRs using the included Soldano Editor Software.
Easy to Dial in Toneshaping
The wide range master Presence control takes you from a tight and mid-focused response to an open, three-dimensional feel. The 3-positon Depth switch fine-tunes the power amp’s bass response. You can boost or cut the bass using this switch. Depth cut is ideal for extended range, low-tuned guitars, allowing you to cut through the mix. Depth boost beefs up single-coil guitars and at lower volumes enriches the bass response.
4-Button Midi Footswitch MIDI Control
An included 4-button MIDI footswitch lets you save and access any combination of channels, Galaxies, and onboard IRs. The amp also accepts external MIDI switchers and controllers, giving you up to 128 user-created presets. You can assign and organize your presets with the included Soldano Editor Software.
The ASTRO-20 combo is loaded with the legendary G12M Greenback from Celestion. Its broad mid-range attack and well-controlled low-end let’s explore every tonal nuisance found in each of the ASTRO’s Galaxies.
