  At GEO, I can understand the titles like 18v from a 9v supply, but don't see any mention of caps values.
  The MAX1044 data sheets show titles I can't make heads or tails out of, [they all look different and are all called "Switched Capacitor Voltage Converters"...dummy can't figure out what does what tho] but show alot of 10uf caps...and some smaller ones.
  Should I just socket these caps and swap for best tone?

The size the capacitor depends on the operation you are performing. Read through the datasheet as it explains some of the conditions of when you would want to use different values. I would say that for most of your applications you will want 10uF. Be aware of the current limitations of charge pump circuits as well.

  Thanks Tone God !
  I went through but couldn't really comprehend all the MAX data info, that sheet has all the subtitles the same, I guess it requires complete read through to understand the chip better, and being hurried like I sometimes am, just want to wire it up and use it instead of having to comprehend first :icon_redface:.
  I can do better by reading the whole sheet, or at least trying again to comprehend it...
