V.L Proctavia (add led and transformer)

[mick77]

.I just need your help if its possible of course .I have the Voodoo lab  Proctavia and i want to converted to negative ground so I could daisy-chain it and finaly i want add a led.Can you tell me what parts i need to buy and how can i do this? (I need a layout for this because i dont know how to read schematics)
Thanks

  converting it to negative ground: just reverse all polarized components that would see reverse voltage polarity.
  Seems invasive and troublesome to me, I'd just as soon build a whole new octave circuit and pedal the way I wanted it.
  MAX1044 voltage converter can provide a reversed voltage supply, there may be a layout in layouts gallery, a bit prettier, especially if there's room in there for the small board [IIRC it's a couple caps and a few resistors and the 8pin chip].
  Completely non-invasive approach: using a separate floating DC supply for each of your pedals. The 'premium' option [costs, but nice and neat, there are advantages to have those floating supplies]. See "Spyder" at GEO, similar to my VDLabs pedalpower II.

Thank you very much for your response.
