I'm an odd duck i guess. I resist boosts and avoid amps that need them, and gravitate to amps that sound great without them. Even when i had my mini rectifier, I would try different boosts in front, and while I'd like the sounds, whenever I compared to the raw amp sound i found I liked that better. I am however coming around to the idea of an added drive boost for solos, but really haven't needed in my 40 odd years of playing.
I will say that my tapping has always sounded anemic, and I believe a boost would probably get it where it should be. So I pretty much have avoided excess tapping, which maybe isn't a bad thing
