3 Channel All-Tube Head - 20 Watts - 4 Galaxy - IR Equipped The ASTRO-20 is a 3-channel, 4-Galaxy, Built-In-USA head 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. 3-Channels of 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.
