Simple EQ – Learn SMD soldering by building two channels of the kind of tone controls you’d find on an old hifi. No voltage control, but just enough range to push sounds into distortion. Works well in a feedback loop.
SMD soldering is not recommended for complete beginners! Make sure your soldering iron has a good fine tip before attempting this build. A flux pen is also recommended.
