Re: Haven't been here in a while, stopping to say hi.
Welcome back dude! Congrats on the A's!
There's nothing wrong with going HH in a strat if you want a bit of thickness. The trick is working with the Strat's natural brightness.
That said, from what you're trying to do, you might wanna think about an HSS strat, with a full size humbucker in the bridge, and a single sized hum in the neck. Plus switches to split the humbuckers and to go series/parallel. It'll open up a lot of options and lots of tones, ranging from classic strat quack to full on thick humbucker, plus a whole bunch of in-between stuff.
I have an HSS as it is. And it's way thicker-than-normal in the neck. Here's where I stand right now with strat configs.
