Gentlemen, may I respectfully suggest you review the DETAILED Presets Templates in "The DROOPY_TX Preset Experience" of the TONE App Support section of the Rumble Club Wiki page, linked in my signature? There are PDF and spreadsheet files that show the DETAILED settings for each of the 100 stock presets on the Stage & Studio amps, and there are blank rows where you can fill in your own new settings! Either print out the PDF version and write on the printout, or use the spreadsheet on your PC to record your settings.
And, please remember, that the Rumble LT25, Studio & Stage sub-thread is specifically intended for such discussions.

And don't go getting crazy ideas about cranking the volume, like Danthoin did. Almost a year and a half after getting my Studio I've still never cranked higher than noon, even with two dozen other acoustic instruments (and my bass volume was only about 7-8!).
