Step 5: Using the Mute
These pickups do pick up extraneous noises like valves and other impacts. The capacitor helps get rid of some of this, but much of this noise is the same frequency range as the trumpet making it difficult to suppress. Its still a fun project to experiment around with and even record a bit of music.
I've attached a sample clip that I made by attaching the pickups to the microphone jack of the computer.
This is my first instructable, so thanks for reading!
