In this series of articles I cover building a simple MOSFET booster. The effect in question is AMZ Mosfet Booster.
This is a simple build, simple circuit to get into pedals designed around MOSFETs. Here’s how the final result looks like:

The articles that are covering this are:
- Breadboarding the effect
- Getting to know the effect
- Analysis in SPICE
- Breadboarding the effect
- Soldering and assembling the pedal
- Deciding on final list of components
- Finishing enclosure
- Where I dabble in decal technique
- Soldering and assembling the pedal
