From the post
Here is a layout for the Catalinbread Galileo MKII, the new, updated version of the well known Galileo.
Info about the original:
The Galileo is a custom-tuned Rangemaster booster combined with the pre-amp section of a Vox AC30 delivering the distinctive throaty mid-range and jangly crunch of Brian May.
The Galileo has three controls tuned to deliver the essence of the Brian May sound - GAIN, TONE, and VOLUME.
With guitar volume knob turned full up, you’ll get the soaring lead tones and tight but aggressive rhythm tones of Brian May.
Turn your guitar volume knob down slightly and you’ll be tying your mother down all night.
Turn your guitar down further and you’ll get an amazing jangly clean sound that isn’t really clean but is!
In a full band context, this pedal will cut through with just the right frequencies to fit perfectly in the mix.
