Catalinbread Galileo - User Manual

Operations Manual
Presenting the Catalinbread Galileo!
The Galileo is a dual function overdrive and booster that gives you the sound and feel of Brian May’s live
rig! Brian plugs his Red Special guitar into a custom treble-booster and a bank of AC30s to get his soaring
overdriven guitar sound with Queen. We took our CB30 Foundation Overdrive (which emulates the AC30
amplier) and our Naga Viper treble-booster (which is our extension of the Dallas Rangemaster treble-
booster) as a starting point, and tuned and rened the sound and response until we got the perfect Brian
May sound. Just plug the Galileo into your amp set to a clean, neutral setting and it will transform it into
the juicy, harmonic-laden, soaring sound that Brian May made famous!
The Galileo incorporates all the hallmarks of our Foundation Series Overdrives, such as extreme touch
sensitivity, clean to scream from your guitar knob, and authentic amp-like playing response that doesn’t
feel like you are playing a “pedal”.
The overdrive and “Top Boost” have separate footswitches that may be used independently. Basically, it’s
two pedals in one!
