converting to 9v positive ground for a brassmaster

[caress]

if i wanted to convert the input section of the brassmaster to positive ground, all i would need to do is switch the polarity of the electro caps, right?

edit:  transistors to pnp as well, obviously...

  Right side Npn, left side PNP?
  I'd put Brass volume ground on the right sides ground.
  the modulator diodes look symmetrical to the E and C transistor outputs...as I'm looking at it.
  I'd like to hear what it sounds like and why it is so...extensive and complicated.
  It's a 'Fuzz'? Looks expensive.
  What is the filter 'drive' and filter 'amp' all about?...
  Drives the filter and that is mixed with the 'brass' to create frequency specific feedback?

well, i'm really only concerned about the "input preamp" (Q1) and "output preamps" (Q6, Q7).   but yeah it's an octaver-type fuzz with a clean blend.
