Boss FZ2 has a very powerfull boost setting which is great for driving tube amps. It also has a powerful eq. Some people requested this, not wanting to build the whole FZ2 circuit which is quite big!
So here is two layouts, one stock with a FET input buffer and a discrete FET/PNP BJT op amp. The other one is Hyped Boost, the "cheat" version with a dual op amp for the input buffer and boost.
