Positive ground wiring... is this correct?

I'm making a Vox Tonbender circuit with two PNP transistors that is positive ground and I've only been doing 'regular' positive ground effects so far, and just want to clarify how it needs wiring up.

I'm just using a 9v battery, so is it just the + and - battery wires that need swapping round?

Normally I've wired the black wire to the input and red to the board,
So for positive ground, do I just need to reverse that and put the red battery to input and black battery to the board?



Ta.  :)

As long as you're only using a battery and will never use an AC adaptor, that's fine. Don't forget that any electrolytic caps will need to be the opposite way round compared to a negative gnd circuit. If you're using a positive ground schematic and layout that shouldn't be a problem, just be aware of putting the negative side to ground 'on autopilot' because that's what you're used to doing (I speak from experience!)

Excellent. I can finally wire it up! Just wanted to double check my gut instinct.

I'm going of IvIark's circuit diagram so the orientation of everything should be fine.

Thanks.
