I would keep it simple on the guitar itself there's too much room for effects on the floor to try and cram them onboard. My suggestion would be a eq or simple preamp/buffer. Although I have always thought a hidden wireless would be cool for a stage rig The setup for my strat is Volume/tone/bass cut with a push pull for the bridge all passive. I have been thinking about swapinf he bridge switch for a phase for the middle pickup.
