Re: 3 x Mini Humbuckers in a strat?
Run a Google search for Vinetto guitars. They use mini-HBs in the neck and middle with a Tele bridge pickup. Their sound clips should give you some idea about the tones you can expect. Hopefully, Randy McFarland will check in, as I think he has a Strat like you're talking about. He has some clips, but I'm not sure which ones feature the "Firecaster".
