Galileo 4K keeps the Rangemaster-Vox pipeline intact but expands the last version's equalization section into a two-band Baxandall EQ to surprising effect. The last iteration of this circuit featured a solitary EQ control called "Tone" that acts as a treble control while fixing the low end. Catalinbread tried swapping out this arrangement for a standard AC30-style tone stack and the result sounded far beyond a simple tweak! Now with the additional tonal flexibility, you can dial in a far greater variety of Vox-like tones that really bloom when pushed by an iconic treble booster circuit. All that same Galileo punch and bite you've come to expect remains untouched, adding a little flexibility to what was once a rather rigid circuit.

- Controls:
TREBLE: This now comprises one-half of the full EQ stack found in a Vox AC30 amplifier. This knob at maximum boosts the helpful frequencies at around 2KHz and above. At minimum, it flattens out every frequency to -20dB from 2KHz upward.

VOLUME: That trusty knob you know and love.
BASS: This knob at maximum boosts the helpful frequencies at around 100Hz and below. At minimum, there's a steeper cut at 200Hz (about -24dB) and a huge cut to the sub bass. While not the intended purpose, the Bass control sounds reminiscent of a "depth" knob that some amps have, which is essentially a bass control taken from the power amp section.

GAIN: Rather than control the gain of the amp circuit, this controls the gain of the treble booster in front. The… read more amp circuit's gain is fixed, allowing to saturate the front end of the amp circuit to your desired level.
