From the post
The Seymour Duncan Pickup Booster offers 25 dB of clean boost with flat EQ (and it's also a line driver). It uses a combination of two NPN and one PNP transistor. Originals use BC107s and BC177s, but other transistors should work fine as well. Check out the demo video below for more info.
