Using this pedal is easy. First, connect it to your guitar setup. Once it's on, you can use your foot on the treadle to control the tremolo's depth and rate. You can also choose different waveforms to get the sound you want. When it comes to the spring reverb, it adds a nice vintage touch to your sound. Just turn it on and adjust as needed. As for maintenance, keep it in a dry place and avoid knocking it around. If it gets dirty, use a soft, dry cloth to clean it. Don't use any harsh chemicals. And always make sure it's properly connected to avoid any sound issues.
