I suspect, that like anything else it's a learning curve and fine tuning your recipe. I have often thought of it myself but just have so little time at the end of the day. With that in mind, I'd really like to try and support little builders. I figure: I build guitars and I like to think that what I can build - even when taking into account a reasonable wage for my labor... is better than what I could buy. I would assume this would be true for pickups as well. Don't get me wrong, I think you can buy a fine guitar or pickup that is mass mfg... and def more consistent, I just think it's the love that we put into building something with our own hands that makes them more unique, more special, and often better tuned in to the player we are.
