I put the EMG SPC mid boost and EXG expander in my Soloist and can really attest to the versatility of that combo.
The pickups from neck to bridge are 89/S/81.
Really, really versatile setup. Love it.
Only thing I noticed is that if you turn up both the EXG and SPC, it does add a fair degree of noise.
But, why would you want to do that anyway?
You could call it "loud"....lots of output.
I also have a strat with the Fender Calpton Mid-boost. That may even be higher output if you crank up the mid boost.
I think Clapton calls it the "saturator" or something. Going into a tube amp, it really pushes the preamp.
Clean becomes crunch, crunch becomes saturation, etc...
