Independent shopping perspective
The Korena take
Soldano’s ASTRO-20 is a 20-watt tube head that pairs a Clean channel and two Overdrive channels with four selectable Galaxy voicings. Green covers clean through lightly pushed crunch, while Blue, Purple, and Red offer progressively more overdrive and can be assigned to the Overdrive channels. Six onboard IR slots can be assigned by channel or Galaxy, so stored presets can carry distinct channel, voicing, and cabinet-simulation choices. It also runs safely without a speaker cabinet for front-of-house, recording, or headphones, with software and an included four-button MIDI footswitch for recall.
Strong match
Who this is for
- Live, rehearsal, and studio rigs needing stored channel, Galaxy, and IR combinations.
- Direct front-of-house, recording-device, or headphone use without connecting a speaker cabinet.
- Players who want separate gain and volume settings for the assigned Overdrive Galaxies.
